Read the full judgment text of LACO 1/1954 on BabelCite. This LACO judgment was delivered on 18 June 1998 before Nazareth V-P, Liu JA, V. Bokhary J.

Civil procedure – subpoena duces tecum – non-party witnesses – discovery – religious trust – Tsing Wan Kun – properties of the To Clan – sub-contract not applicable – Secretary for Justice in dual capacities as parens patriae and representative of Government Departments – plaintiffs conceded Government Departments not sued – Government Departments ceased to be parties – five writs of subpoena duces tecum issued to five non-party Government Departments requiring production of entire contents of approximately 32 original files identified only by file references – whether writs amount to impermissible general discovery from non-parties – whether documents sufficiently identified by particular description – whether trial judge entitled to infer relevance based on 'past experience' with four other files – whether Secretary for Justice's dual role justified distinction from third-party subpoena – whether interlocutory appeal should be permitted – held: appeal allowed; writs set aside – general principle that non-party witness cannot be compelled to give discovery of documents – subpoena duces tecum limited to documents that are evidence in the case, i.e. both material and admissible – R v Clowes distinguished as a criminal case applying English statutory test not applicable in Hong Kong – Matthew & Malek on Discovery requirement of particular description – attempt to obtain entire files where contents not known is a discovery exercise, not the production of identified evidence – trial judge's inferential finding of relevance based on 'past experience' could not stand as he had no sight of the 32 files and no evidence of their contents – dual capacities of Secretary for Justice must be kept distinct – fact that same Hong Kong Government is involved does not convert non-party subpoena into party discovery – privilege and public interest immunity militated against sustaining writs – interlocutory appeals to be discouraged in matters inter partes but non-parties being vexed by massive production orders must be permitted to appeal – order nisi for 75% of appellant's costs reflecting that inconsistent and confusing stance originally adopted contributed to bringing the appeal – 75% of costs of the appeal awarded to the Secretary for Justice

Legal issues: Whether five writs of subpoena duces tecum directed to non-party Government Departments amount to impermissible general discovery · Whether the trial judge's inferential finding of relevance could stand on the basis of 'past experience' with prior discovery · Whether the Secretary for Justice's dual capacities (parens patriae and representative of Government Departments) justified the issuance of the subpoenas · Whether interlocutory appeals during trial should be permitted in the circumstances

Outcome: Appeal allowed. The trial judge's order refusing to set aside the five writs of subpoena duces tecum is set aside, and the five writs of subpoena duces tecum are set aside.

JUDGMENT

-----------------

Nazareth V-P:

Introduction

1. This is an appeal brought by the Secretary for Justice in her capacity as representative of the Secretary for Home Affairs, the Director of Home Affairs, the Director of Lands, the Lands Registrar and the District Office Tuen Mun ("the Government Departments"). The appeal is from an order of Yam J dismissing a motion taken out by the Government Departments seeking to set aside five writs of subpoena duces tecum issued by the plaintiffs.

Background

2. The action in the context of which the appeal arises concerns properties of the Tsing Wan Kun, which may be loosely described as a religious trust. The properties comprise a temple and a substantial amount of land. It is consolidated action which started life as two originating summonses, one issued by the Attorney General (as representative of the Crown as parens patriae) under Order 120 of the Rules of the Supreme Court, for the administration of public charitable trusts; and the other by the current 3rd defendants as dignitaries in the New Territories concerned with the proper administration of the charity. The result of the consolidation is that the To Ka Yi Tso and various persons surnamed To representing other male descendants of the To Clan were constituted the plaintiffs to assert their claim that the properties in question belong to them. The Secretary for Justice (in her capacity as representative of the SAR as parens patriae) is the 2nd defendant ("D2"). D2 claims that the Tsing Wan Kun is a public charity. The 1st defendant, Pui Man Yau alias Sik Kwok Wah is the present abbot of the temple, and he makes his own claims to the properties by way of counterclaim. The 3rd and 4th defendants play no part in the proceedings. The 5th defendant, i.e. the estate of Tat On, was joined recently as a necessary party since the plaintiffs were claiming that Tat On, a monk involved in the matter, had acted wrongfully in his dealings with certain of the properties.

3. The hearing of the action commenced before the late Jerome Chan J on 3 March 1997. By the time the trial came to its premature end on 27 March 1997, substantial evidence had already been called by the plaintiffs. The re-trial came before Yam J on 9 March 1998.

4. In the course of the opening by leading counsel for the plaintiffs, the question arose as to whether the Secretary for Justice had been sued not only as parens patriae but also in her capacity as the representative of the Government Departments. This led to extensive and protracted arguments apparently over many days between counsel for the plaintiffs and counsel for D2. The arguments were centred mainly on the pleadings, in particular, the averments relating to:

(a) How the District Officer dealt with an application by Tat On for registration as manager of the properties under s.15 of the New Territories Ordinance.
(b) The approval of the sale of certain properties made by Tat On.
(c) The refusal by the District Officer to register another monk, Mun Sang, as manager.
(d) The acceptance by the Crown of the surrender of certain properties by Mun Sang.

These averments are of some significance in the context of this appeal for they are relied upon by the plaintiffs as indicating the nature of the involvement of the Government Departments in the subject matter of the action.

5. Yam J ruled on the arguments on 27 March 1998, holding that Secretary for Justice in her capacity as representative of relevant Government Departments had been sued as from the date of service of the writ. D2, appealed against that ruling to the Court of Appeal. The Court of Appeal, differently constituted, noted that Secretary for Justice in her capacity as representative of the Government Departments had not been heard on the ruling and intended to apply to set aside the ruling. In those circumstances, the Court made an order that upon the setting aside of the ruling, the appeal be dismissed.

6. On 14 April 1998 counsel appeared before Yam J on behalf of the Secretary for Justice in her capacity as representative of the Government Departments and sought to set aside the 27 March 1998 ruling. The ruling was in the event set aside upon the consent of the plaintiffs. Before counsel for the Secretary for Justice (representing the Government Departments) embarked upon his substantive submission on whether the Secretary for Justice in that capacity had been joined, leading counsel for the plaintiffs conceded that the Secretary for Justice in her capacity as representing the Government Departments had not been sued and further indicated unequivocally that the plaintiffs had no intention to sue the Government. Upon that concession and indication, the Secretary for Justice (representing the Government Departments) took no further part in the proceedings. The plaintiffs then proceeded to apply for and obtain leave to make further amendments to their Statement of Claim making it clear that no relief was sought against the Government.

7. I pause here to note that the result of the concession, the Secretary for Justice's response in not taking further part in the proceedings, and the plaintiffs' amendments to give effect to their concession, had a crucial consequence from which the plaintiffs cannot resile, i.e. the Government Departments ceased to be parties to the action (not that they ever were parties on the evidence). As will be seen, that factual position has far-reaching consequences in this appeal.

8. Returning to the facts, on or about 5 or 6 May 1998, the plaintiffs issued five writs of subpoena duces tecum directed to each of the Government Departments. They were in identical terms. They each required the production of "the following documents":

"All those original files and the entire content thereof, from which discovery of some of the contents therein had been made in the above action by the 2nd defendant in the List of Documents of the 2nd defendant dated 23 December 1996 and in the Further and Better List of Documents of the 2nd defendant dated 19th February 1997, true copies of which are attached hereto ('the said Original Files').
          The said Original Files are better described in the said list of documents of the 2nd defendant as per the following headings and/or titles:
List of Documents of the 2nd Defendant
(a) District Office TR PS 2/3/64
(b) District Office TM 16/5/C
(c) District Office TM 16/5C II
(d) District Office TM 16/5C III
(e) LR TM 221/2/24
(f) Lands Dept LACO 1/1954/69 (N.T. Section)
(g) Registrar General's Department TMNTLR 4/218/87(1)
(h) District Officer, Tuen Mun
(i) Registrar General's Department TMNTLR 4/218/87(2)
(j) Lands Department LM(27), TMNTLR 1/218/92
(k) Director of Home Affairs
Further and Better List of Documents of the 2nd Defendant
(l) Tso Tong Department File of the Ling To Tsz
(m) Tso Tong Department File of Ling Wan Tsz
The said Original Files shall include all the minute sheets (together with all the papers and documents at float, if any), and all memoranda, correspondence and documents contained in the enclosures."

I pause again here to call attention to another fact that also assumes crucial significance in the appeal. The "documents" required are entire "original files", i.e. their "entire contents".

9. The events that led to the issue of the five writs of subpoena were as follows. D2 had in the course of the proceedings made two lists of documents for the purpose of discovery of specific documents. Some of the headings to groups of individual documents in the lists identified the files from various Government Departments which contained those particular documents, and others identified the affirmations to which the related documents had been exhibited. It should be noted that the schedule did not include four files which had been discovered, been inspected by the plaintiffs' advisers, and then apparently returned to the Government Departments concerned. It should also be noted that all the "documents" required were in fact complete files and some of the particular items listed comprised several files. Mr Yu stated that his instructions were that the files were very substantial. The reference to the District Office Tuen Mun embraces no less than 20 files, of which two belong to the District Office Yuen Long. The reference to the Director of Home Affairs embraces eight files.

10. The appellant i.e. the Secretary for Justice in her capacity as representative of the Government Departments, issued a notice of motion to set aside the writs of subpoena on the ground that they were fishing, speculative or oppressive. Yam J dismissed the motion, giving an oral ruling, and subsequently releasing a written judgment.

11. In his judgment, Yam J set out the general principles applicable to the issue of a subpoena duces. tecum with extensive supporting citations. The latter are also reproduced here to illustrate the general and some specific aspects of legal position in point:

"1. There shall be no discovery from a non-party to an action subject to certain exceptions which are not applicable to the case before me. In Macmillan Inc v. Bishopgate Investment Trust Plc [1993] 1 WLR 837 at 843 per Millett J:-
'...the fundamental rule that a mere witness is not amenable to discovery, and cannot be subpoenaed to produce documents so that a party to litigation can examine them in order to decide whether or not he wishes to make use of them.'
(Decision approved by the Court of Appeal reported at [1993] 1 WLR 1372.)
2. A subpoena should not be used for making discovery only. In Panayiotou v Sony Music Ltd [1994] Ch 142 at 151 per Sir Donald Nicholls V-C:-
'... discovery of documents is obtainable only from persons who parties to the action. In the normal way, parties are compelled to produce for inspection all their documents relating to matters in issue in the action. Persons who are not parties are not subject to such a far-reaching obligation. They can be compelled to give evidence at the trial, either by way of oral testimony or by being required to produce documents. But it is established that a subpoena to produce documents cannot be drawn so widely as to amount to requiring the witness to given discovery. The object of the subpoena is to compel the witness to produce evidence directly material to the issue in the case. The object is not to require him to produce documents just because they may be useful for the purpose of corroborating or challenging a witness, or because they may lead to a train of inquiry which may result in the discovery of evidence or may, in some other way, advance one party's case or damage the other's. Nor is the witness to be required to undertake an unfairly burdensome search through his records to find this or that document or to see if he has any documents relating to a particular subject matter ...'
Further in The "Lorenzo Halcoussi" [1988] 1 Lloyd's Rep 180 at 184 per Styen J:-
'But it is clear that under our law a party to litigation cannot obtain discovery against a third party except in certain exceptional cases.'
In Hsin Chong Construction Co Ltd. v Hong Kong and Kowloon Wharf Godown Co Ltd [1986] HKLR 987 at 990 per Hunter J (as he then was) :-
'... There is ample authority for the proposition that you cannot get general discovery by a subpoena in this way. That in itself is sufficient to discharge this part of the subpoena ... it is quite obvious that it would be a very careful, lengthy process to ascertain which documents there are, which are relevant and which exist in the architect's files, as against those which are already in evidence and disclosed before the arbitrator. No one can start with that process without having a complete list of the documents before the arbitrator. With that in front of him, he will then have to go through the architect's files; find out what is there which is not in the list and consider whether any of those documents are privileged or relevant or what. This is a very lengthy process. I cannot accept that any witness can be required to go through that process. ... I need say no more about the duces tecum aspect of this because that seems to me really to collapse under its own weight.'
3. A subpoena should not be used as a fishing exercise for documents nor speculative. See Senior v Holdsworth ex parte I.T.N. [1976] 1 QB 23 at 35 and Wakefield v Outhwaite [1990] 2 Lloyd's Rep 157 at 162. Again in The "Lorenzo Halcoussi" (supra) Steyn J at 185 stated:
'... They have also included in the subpoena a whole range of categories of documents customarily asked for on discovery, on the speculative basis that it may turn out that some may exist and if they do exist some of them may be relevant....'
The subpoena was set aside in this case as being too wide and speculative.
4. A subpoena should not be oppressive to the witness when, say for instance, the terms are too wide. The party issuing the subpoena (the Plaintiffs herein) has to show that these witnesses are required to produce relevant and admissible evidence for trial and that those documents to be produced must be required and are necessary for the fair disposal of the case. See The "Lorenzo Halcoussi" (supra) at 184; and Overseas Trust Bank Limited v Coopers & Lybrand HC Action No. A5764 of 1986, where Godfrey J (as he then was) citing Burchard v. MacFarlane [1891] 2 QB 241 at 247-8 said:
'... A subpoena duces tecum was an order from the Court to a person to produce a document which was alleged to be in his possession - to produce it to the Court at the trial, and not to produce it to the parties, for, under a subpoena duces tecum, when a witness brought the document into Court the parties could not ask for it. The parties have no right to see it, and all that could be done on a subpoena duces tecum was that the witness produced the document to the Court, subject to the order of the Court, not to the parties; and he might insist that his document should not be handed to the parties even at the trial. All that could be done was that the judge, when he was satisfied that it was evidence in the case for either of the parties, might order it to be read.
So, in the case of a subpoena duces tecum, the judge must be satisfied that the document is "evidence in the case for either of the parties", but in the case of discovery, the documents to be produced are not confined to those, which would be evidence either to prove or disprove any matter in question in the action. It is obvious that the class or classes of documents which may be required to be produced on subpoena is much more restricted than those which can be required to be disclosed on discovery. In the former case, the documents must be necessary evidence in the action.'"

12. I pause here to observe with reference to the judge's second principle that the word "only" can be misleading.

13. Having set out the foregoing Yam J continued:

"However, the case before me is in my view different from those cases cited where the aforesaid general principles were applicable. I shall set out those distinguishable features in this case in the next section."

14. Before coming to those features, it has to be mentioned that while both Mr Yu for D2 and Mr Barlow for the plaintiffs generally accepted the judge's principles and authorities, both made some submissions on them although, I think, those could be said to have been more a matter of emphasis than of disagreement.

15. Mr Yu sought to emphasise in particular the following matter, i.e., the necessity for particularity of identification of documents required by a subpoena duces tecum. This he did by reference to the following passage in the judgment of Sir Donald Nicholls VC at p153 of Panayiotou v Sony Music Ltd [1994] Ch 142:

"I preface consideration of the documents sought by noting that particularity of identification or description is a matter of degree. The description used, moreover, may be important in another way: it may throw light on the purpose for which the documents in question are sought. The court should be astute to see that what is essentially a discovery exercise, whereby the applicant is seeking production of documents with a view to ascertaining whether they may be useful rather than with a view to adducing them in evidence as proof of some fact, is not disguised as an application to produce particular documents. Where an applicant has not seen the documents sought and does not know what they contain, the application can the more readily be characterised as a discovery exercise ..."

and at p. 155 which has a helpful reference to files:

"Likewise with item 1. This comprises the files containing SMEI's internal notes and memoranda and communications with the defendant, concerning the negotiation and conclusion of the recording agreements in 1987 and 1988 and the subsequent variations in October and December 1988 and July 1990. A file is a folder containing one or more documents. Here, the files are likely to contain a wide range of documents, internal memoranda, notes on meetings and telephone discussions, drafts of letters and agreements, correspondence and so forth. The plaintiffs do not know what the files contain. They seek production of their contents, whatever they may be. This is a discovery exercise."

The latter observations are particularly apposite to the situation in this case. Mr Yu emphasised the passage from the judgment of Hunter J in Hsin Chong Construction Co Ltd v Hong Kong and Kowloon Wharf Godown Co Ltd that I have already reproduced. He relied also upon the following statement in Matthew & Malek on Discovery (1992) at paragraph 3.72.

"Identification The subpoena or summons itself must identify the documents required, by means of a particular description, and not a general description." (Att.-G v Willson (1839)9 Sim. 526)

16. Finally, Mr Yu relied upon the passage that has already been cited from the judgment of Godfrey J in Overseas Trust Bank Limited v Coopers & Lybrand.

17. Mr Yu submitted that upon the authorities cited by Yam J and in addition those he himself relies upon, the five writs of subpoena clearly infringed the well established principles referred to in those authorities, and are objectionable as being (i) speculative, (ii) an attempt to seek discovery from witnesses, (iii) too wide and oppressive, and (iv) as not having been shown to be required as relevant and admissible evidence.

18. For his part, although Mr Barlow accepted the judge's identification of the relevant principles of law applicable and the various authorities proclaiming them, he nevertheless argued that it is sufficient if the documents required are likely to be relevant or are arguably relevant, and it would seem that his argument was also that the documents need not be material required as evidence in the action. I shall return to those submissions.

The plaintiffs' submissions

19. Mr Barlow submitted first of all that there was no general discovery sought by the plaintiffs, in that the witnesses subpoenaed were not required to undertake any search whatsoever since the files required to be produced had been identified and retained. Moreover, he submitted, the Government Departments were only required to transport the files to court, produce them and leave, since all searching, evaluation, etc had already been undertaken by the Government counsel concerned.

20. To understand and address that submission, it is necessary first of all to turn to the version of the facts that he relies upon. Earlier in the proceedings, the plaintiffs' legal representatives were permitted to inspect four files from which a number of individual documents had been discovered. Indeed, it is said that counsel for D2 referred to the four files in the process of cross-examining the plaintiffs or their witnesses; however, it transpires that it was only to documents that had been disclosed that such reference was made. Leading counsel who represented the plaintiffs at that time looked at the four files. We are told that as a result his view was that the files were each in respect of one separate subject. He is recorded as wondering if it would be convenient for the plaintiffs also to be given discovery of the original District Office file in relation to the Tsing Wan Kun. Yam J commented that he was sure that counsel for D2 was more than willing to dig up all the relevant documents and he did not think that they had to argue about discovery. The judge asked to see and referred to two of the four files, remarking that they were quite massive and counsel would have to look at them together first. From the record, it is also clear that counsel for D2 was quite prepared at that stage to have the four files referred to and to produce documents from them. Subsequently, they were returned to the Government Departments concerned and were not produced by counsel when they were again requested by the plaintiffs. However, it is important to bear in mind that none of those four files is the subject of any of the five writs of subpoena duces tecum.

21. It also appears that in relation to those four files, that there were relevant documents that had not been included in D2's original discovery. Upon that basis, it is submitted on behalf of the plaintiffs that it is highly likely that, similarly, further relevant documents are most likely to exist in the 32 files requested which do not appear in the two discovery lists submitted by D2.

22. Reverting then to Mr Barlow's submission, it can be seen quite clearly from D2's lists of documents discovered that they simply do not discover any files. What they do is discover individual documents numbered 1 to 305 grouped for convenience by reference to the files in which they are contained, the affirmations to which they are exhibited, or even by Government offices or departments to which they presumably belong.

23. Mr Barlow has argued strenuously that the entire files are likely to be relevant and material. D2's further and better list of documents, he points out, was verified by Administrative Officers from the Home Affairs Bureau and Department. He adds that leading counsel for D2 put to witnesses documents that had not been provided to the plaintiffs in the two inspection-by-copies exercises and when challenged, submitted that D2 had discovered the files, which had earlier been available for inspection, but had since been returned to the Government Departments. Counsel also confirmed that the files exist, that they were relevant to the trial issues, that they had been identified and were then available for production by the Government officials holding them. But when the plaintiffs obtained the five writs of subpoena the Secretary for Justice, he complained and challenged the five writs of subpoena. Moreover at the 12 May 1998 hearing Mr Yu had confirmed that the files were in the court building. I pause here to note that Mr Yu disputed some of those facts. But for reasons that will become clear, it is not necessary to deal with that conflict. Reverting to the factual background relied upon by Mr Barlow, Yam J, he said, found that the compilation of D2's lists of documents had not been correctly or conscientiously carried out. He submitted that it was in the light of his experience of all of that, and weeks of evidence, against the background of the pleadings - including the pleadings and the four averments mentioned, that the judge concluded and was entitled to conclude that the files sought were relevant and material evidence for the trial.

24. That submission disregards the fact that the judge has never seen the 32 files, and that there undoubtedly will be documents in the files that are not material, not relevant and not required as evidence. More to the point it overlooks the general principles relating to a subpoena duces tecum and the thrust of the authorities cited that Mr Barlow has conceded require documents to be identified. Not only are documents not identified, but the files will have to be gone through to identify them. To say that it is known that the documents exist, as Mr Barlow does, is to miss the point. Of course, the contents of the files do exist. But it is not true to say that all the documents in the files are relevant and material evidence, or that all such have been identified. That will have to be carefully done, given the experience of discovery in relation to the four files, and the nature of the four averments mentioned earlier, which must require public and the Government's interests to be protected in the ordinary way. It is difficult to simply reject Mr Yu's submission of oppression out of hand, even if one has some sympathy for the plaintiffs in regard to the inconsistent and somewhat confused manner in which those representing D2 have approached the matter of discovery and inspection. But the battle lines and the Secretary for Justice's position are now clear. And at the end of the day inconsistency and generosity in voluntary disclosure cannot be a substitute for the established criteria regulating the issue of a subpoena duces tecum - a fortiori where the inconsistency, earlier discovery of files, and other conduct relied upon were not that of the Government Departments sought to be subjected to the writs of subpoena. Moreover in treating every single document in the files as relevant and necessary evidence notwithstanding that all of them have not been identified and their contents not known and not even individually claimed to be relevant and material, it seems to me that the judge clearly erred in law, in principle and upon the facts in concluding that all the files in entirety were relevant and necessary evidence required for the action. The appeal must succeed on this point alone, for the necessity for the documents sought to be both material and required cannot be substituted or displaced; that is in any case not suggested.

25. Nevertheless I turn then to Mr Barlow's submission on relevance. This he founds upon the following words of Steyn J (as he then was) in The Lorenzo Halcoussi at p. 184:

"... the document or documents to be produced must be required or relevant and admissible evidence or must at least arguably and on reasonable grounds come in that category ...
          And ... the burden is on the party defending the subpoena to show that it is not a mere fishing or speculative expedition, but that the subpoena relates to documents which are likely to exist ..."

26. There can be no dispute, Mr Barlow submitted, that the files in question are known to be in existence. However, I do not read the latter words of Steyn J as a general proposition that that if documents are known to exist, then the relevant subpoena cannot be a mere fishing or speculative expedition. That may be so where there is no question of relevance or admissibility. But here both matters are very much in issue since the contents of most of the documents in the files are not actually known. Accordingly, in the particular circumstances, it would be in the nature of fishing or speculation to require all those documents to be produced, in effect to see which, if any, documents would be material evidence required, or relevant and admissible evidence (and in effect which would not). That, incidentally, is exactly what discovery entails.

27. I add that for the reasons already indicated, I reject the submission that relevance is established by the ruling of the judge to that effect with the benefit of many weeks of submissions and evidence. There was no evidence of the contents of the files, much less evidence of the entire contents of all that files. Nor do the plaintiffs know the contents of the files, a fortiori all the contents of all the files.

28. Mr Barlow sought also in a similar vein to rely upon R v Clowes [1992]3 All ER 440. Two issues were canvassed before Philips J there. The first was whether Mr Jordan was in a position to satisfy him that the documents he had been required to produce were not "likely to be material evidence". It is important to note at the outset that those words, "likely to be material evidence", were not being there adopted as some sort of criteria that the courts had formulated to regulate the production of documents by witnesses. They were in fact the criteria provided by s.2(2) of the Criminal Procedure (Attendance of Witnesses) Act 1965. There is no suggestion that any similar statute applies in Hong Kong. To breach that gap, Mr Barlow took us to Macmillan Inc v Bishopsgate Investment Trust Plc [1993] 1 WLR 837 at 841H, 842A-B where the following passage appears in the judgment of Millet J (as he then was):

"Mr Haas is a third party for this purpose. He cannot be compelled to give discovery of any document in his possession merely because it may be relevant to an issue in the case. He is, of course, amenable to the process of subpoena duces tecum, but that has always been limited in the past to evidence which is both material and admissible. See R v Cheltenham Justices, Ex parte Secretary of State for Trade ... and the line of cases following it which were concerned with criminal cases. In my judgment, the same principle applies to civil proceedings.
          In Reg v Clowes ... the liquidators were served with a witness summons issued under section 2 of the Criminal Procedure (Attendance of Witnesses) Act 1965 to produce transcripts of evidence given to them by witnesses who had been examined voluntarily. The liquidators applied to set aside the witness summons. Phillips J held that a witness summons issued under that section had to relate to evidence that was not only material but also admissible, to that extent following Reg v Cheltenham Justices, Ex parte Secretary of State for Trade ..., but he was able to uphold the witness summons on the ground that in that case the transcripts would be admissible evidence under section 24 of the Criminal Justice Act 1988, ...
          In that case the witness summons was served before the beginning of the trial, with a view to obtaining the transcripts partly as material for cross-examination ... and partly to ascertain whether they contained helpful material which could be obtained from the witnesses if called by the defence. Phillips J was satisfied by what he was told, that it was not unlikely, but on the contrary was likely, that the defence would wish to adduce as evidence statements made in the interviews recorded in the transcripts. He came to the conclusion that the mere fact that the defence might in addition be hoping to find inconsistent previous statements made by prosecution witnesses was not sufficient for him to exercise his discretion against upholding the witness summons."

I do not think this passage avails Mr Barlow. In the first place, Millet J's reference to the same principle applying to civil proceedings was a reference to the principle that the process of subpoena duces tecum has always been limited in the past to evidence which is both material and admissible. Secondly, the test that the document was "likely to be material evidence", came from s.2 of the Criminal Procedure (Attendance of Witness) Act 1965, which as I have said, does not apply in Hong Kong, nor is there a corresponding local provision. Moreover, in Macmillan, having already been concerned in the Clowes case in the way apparent from the judgment of Philips J, Millet J ultimately declined to uphold the subpoena to produce documents, and said that if it were necessary to distinguish Clowes, he "would do so first on the ground that that was a criminal case and secondly, more importantly, that in that case the court was satisfied that the defence would probably wish to adduce the documents in evidence."

The "distinguishable" features

29. Mr Barlow significantly did not make any submissions to support these features other than to say that he adopted Yam J's reasons for his decision. Mr Yu submitted in effect that what were claimed as "distinguishable" features did not avail the plaintiffs.

30. I turn then briefly to the "distinguishable" features relied upon by Yam J, to displace the principles he had identified. I adopt the numeration which he gave them, indicating first the particular feature, and then my view upon it:

(1) "(a) The files kept by the five Departments were previously stated with the names and/or numbers in the 2nd Defendant's Supplemental List of Documents and the voluntary Further List of Documents. The 2nd Defendant, the Secretary for Justice, was in this case appearing in her limited representative capacity as parens patriae. In other words, she had power to call for these files and retain in her possession for inspection."
          That view, with respect, confuses the two capacities in which the Secretary for Justice has to act. She could not properly call for the files in her capacity as representative of the HKSAR as parens patriae. I pause to observe that the comments of the judge here are a strong indication that he did in fact confuse the two capacities or not appreciate them.
(2) "(b) Now all these five Departments are separately represented. Apparently they refused to produce or hand over them to the 2nd Defendant or even to the Court unless, as stated in their previous letter, they were subpoenaed by the Court. When they are now subpoenaed, they now object to the subpoena on those aforesaid stated grounds."
          If the judge, not to say the plaintiffs found D2's stance inconsistent and even infuriating, that is entirely understandable. But it does not in any way alter the legal position. As non-parties to the action, the Government Departments cannot be required to make discovery. The inconsistency and refusal to hand over the files could not provide the necessary legal foundation for a subpoena duces tecum; moreover, it was the inconsistency of D2 and not the Government Departments.
(3) "(c) At the trial, the 2nd Defendant [D2] was still in possession of four files in respect of [the four files already mentioned]. There is no explanation why [D2] could only retain these four files."
          Again this confuses the two roles of the Secretary for Justice.
(4) "2. (a) In respect of the aforesaid four files produced to Court, there are other documents (e.g. the document at float, the minute sheets and other documents) not specifically listed and disclosed or discovered but shown to be are either relevant or relevant to give a fuller or complete picture of the issue before the Court."
          The relevance of this feature is not entirely clear. In any case the likelihood that, because all relevant documents in the four files were not discovered, the same has or would be repeated with respect to the thirty-two files, is questionable and besides does not avail the plaintiffs for the reasons already given.
(5) "(b) Someone (the one who sworn to the List of Documents is an Administrative Officer) must have gone through the files and selected some documents therefrom. Without blaming anyone for doing it intentionally, the exercise was not properly done. [Senior counsel for D2] could not be responsible for the selection as, apparently, he was not familiar with how to read a government file, and he could not have advised on their relevance and discoverability."
          The judge was plainly right in his conclusion that the first list of documents was not properly done. This is clear from the fact that a second supplemental list was ordered by Jerome Chan J which did result in the supplementary list. But how that could justify the writs of subpoena duces tecum remains unexplained.
(6) "(c) From this past experience, the Plaintiffs have satisfied me that there is a real likelihood that those documents in those files will be adduced into evidence and they are relevant to those issues before the Court for the fair disposal of the case. In R v Clowes ... it was held that where a document is likely to contain material evidence, the precise nature of which is not known to a party, the issue of a witness summons by that party is likely to be motivated both by a desire to see the contents of that document and a desire, conditional perhaps upon the precise nature of those contents, to adduce the evidence in the trial."
          The judge then went on to rely upon Clowes, which is a matter that has been addressed in the context of Mr Barlow's reliance upon that authority.
(7) "3. All those files now under subpoena to be produced to Court are being kept by these five Departments, not just for themselves but in general for the Hong Kong Government. It is the same Hong Kong Government as represented by the Secretary for Justice. But of course she is only appearing in her limited representative capacity as the 2nd Defendant herein as parens patriae. Albeit it is the same Hong Kong Government who is in possession of these documents, thus it is not quite a case of a subpoena served on an entirely different third party as in those cases cited."
          If what the judge implies here is that notwithstanding that D2 appeared in her limited capacity as representative of the SAR as parens patriae, the fact that she ordinarily represents the Hong Kong Government as the Secretary for Justice somehow has the result that it is not quite a case where the subpoena is being served on an entirely different third party, than that is a view that cannot be supported in law or fact for the reasons given.
(8) The fourth distinguishable factor, i.e. D2's point that a claim for privilege might be raised later was rejected by the judge as a ground for objection to the production of documents not covered by privilege. It is only necessary to say that privilege could be involved, particularly given the nature of the four averments mentioned earlier. That could only militate again the writs of subpoena being sustained. However, the point is of minor significance.

Interlocutory appeals to be discouraged

31. There remains to be dealt with Mr Barlow's point that interlocutory appeals during trial should be discouraged (see the Supreme Court Practice 1997, Vol. 1, p.364 para. 20/5-8/15), also Lam Choi King v Yeung Fook Chi and others [1991] 1 HKC, 219 CA at 226G-227D).

32. That principle is not in doubt, and has been reinforced by the increasing emphasis by this Court upon case management by the trial judge. However, here it is a matter of non-parties being vexed and probably also oppressed by having to examine the massive files involved. Moreover, it is not a question of the particular matter being capable of being remedied on appeal post trial, as is ordinarily possible in matters inter partes. While not underrating the disruptive and potentially prejudicial effect of this appeal upon the plaintiffs, particularly in the context of prolonged hearings, I have no doubt that the non-party Government Departments must be permitted to proceed with their appeal.

33. I accordingly have no hesitation in rejecting Mr Barlow's submission.

Conclusion

34. For the reasons I have endeavoured to give, I would allow the appeal. As to costs it seems to me that the costs of the Secretary for Justice as representative of the Government Departments have been significantly contributed to by the inconsistent and somewhat confusing stance originally adopted on her behalf, which in part brought the appeal upon herself. I would accordingly order nisi that she is to have only 75% of her costs of the appeal.

Liu, JA:

35. Before us, leading counsel for Secretary for Justice (for the five Government Departments concerned) Mr Yu reaffirms that "if the plaintiffs are able to identify precisely which documents among these numerous files they wish to be produced by way of relevant and admissible evidence, the various Government Departments would, subject to any claim of privilege or possible public interest immunity, have no objection to producing these files". That sums up what a stranger to an action could lawfully be compelled to produce.

36. Yam, J. was satisfied by "past experience" that the documents in what we now know to be some 32 files kept by these five Government Departments were "likely to contain material evidence" relevant to the fair disposal of the issues before him. Five subpoenae duces tecum were issued, and the judge refused to discharge them primarily on his inferential finding. By "past experience", the judge referred to conduct of counsel and the procedure jointly adopted for processing four other Government Department files during the hearing. Could this inferential finding of the judge based on "past experience" be overturned? This aspect has greatly troubled me in this appeal. It is to be noted that the five Government Departments are not resisting, perhaps understandably, the subpoenae on the ground of claimed irrelevance or inadmissibility but that the issuance of these five writs of subpoena is sought to be challenged on first principles. But my Lord, the Vice-President has alluded to the fact that the judge had no sight of these 32 files. The observation made during the hearing before Yam, J. by Mr Fung, leading counsel for the Secretary of Justice (but not acting for these five Government Departments) that joint inspection of Government files would be expected to be productive was not an admission as to relevance or otherwise of their contents. No such concession was or could have been made even for the four files from which documents were then extracted jointly by counsel for use or production. Insofar as counsel's observation could be understood to have been made by reference to relevancy, he merely "suspected that the original files .... would have the same function". Counsel was doing no more than airing his personal satisfaction that the co-operative spirit in sorting out documents was highly commendable and that the same process for other Government Department files would likely be productive. His remark was made exclusively on the modus operandi. There is no clear evidence that these 32 files were all in court or that counsel had perused any of them. As a matter of fact, the judge was able to say that Mr Fung S.C., counsel for Secretary for Justice, "was not familiar with how to read a government file and ...... could not have advised on their relevance and discoverability." Mr Fung was not acting for these five Government Departments and had certainly no instructions to make any concession. It was also inaccurate to assume that all or part of these Government Department files had been discovered in the lists of documents. What happened was: in the headings of various sections of the lists, the Government Department files were identified as the source for the specific documents therein disclosed. Clearly, "past experience" could not assist the judge. There was no or no sufficient material for the judge to make a finding on the nature of the contents of these 32 files. It was not open to the judge to conclude that there was "a real likelihood that those documents in those files ....[were] relevant ..... [or] likely to contain material evidence". His inferential finding cannot stand.

37. The respondents have not been able to identify any material documents in these 32 Government Department files. The trite principles apply. On what has transpired, these Government Departments are not shown to have acted unreasonably. The circumstances were unusual but there would seem to be no warrant for sustaining the five writs of subpoena.

38. I have had an opportunity of reading in draft the judgment of the Vice-President. I agree with his conclusion for the reasons he gives. I, too, would allow this appeal with an order nisi for costs the Vice-President proposes to make.

V. Bokhary J:

39. I respectfully agree with my Lord the Vice-President and Mr Justice Liu J.A. Like them, I too would allow this appeal to set aside the five subpoenae duces tecum in question and make an order nisi awarding the Secretary of Justice 75% of her costs of the appeal.

40. As it seems to me, nothing which Mr Barlow for the Plaintiffs has urged can deflect the conclusion that what his clients have done amounts to an attempt to obtain general discovery by way of subpoena. It is a well-established general principle that such a course is not permissible.

41. The cumbersome state into which civil litigation has gotten itself does not dispose me towards drawing fine, or even not so fine, distinctions on the facts of particular cases so as to create exceptions to that salutary rule. But even if I were so disposed, I would not regard the circumstances of the present case as appropriate for the creation of any such exception.

Nazareth V-P:

42. The appeal is accordingly allowed and the judge's order and the five writs of subpoena set aside. There will also be an order nisi that the Secretary for Justice in her capacity as representative of the five Government Departments is to have 75% of her costs of the appeal.
