Consolidation of appeals 14 1 Subject to paragraph (2) below, where in the case of two or more appeals to which these Rules apply it appears to the Tribunal– a that some common question of law or fact arises in both or all of them, or b that for some other reason it is desirable to proceed with the appeals under this rule, the Tribunal may order that the appeals be consolidated or heard together. 2 The Tribunal shall not make an order under this rule without giving the parties and the relevant Minister an opportunity to show cause why such an order should not be made. Directions 15 1 This rule is subject to rule 16 below. 2 In this rule, references to a “party” include the relevant Minister notwithstanding that he may not be a party to an appeal under regulation 32(6) of the Regulations. 3 Subject to paragraphs (6) and (7) below, the Tribunal may at any time of its own motion or on the application of any party give such directions as it thinks proper to enable the parties to prepare for the hearing of the appeal or to assist the Tribunal to determine the issues. 4 Such directions may in particular– a provide for a particular matter to be dealt with as a preliminary issue and for a pre-hearing review to be held; b provide for– i the exchange between the parties of lists of documents held by them which are relevant to the appeal, ii the inspection by the parties of the documents so listed, iii the exchange between the parties of statements of evidence, and iv the provision by the parties to the Tribunal of statements or lists of agreed matters; c require any party to send to the Tribunal and to the other parties– i statements of facts and statements of the evidence which will be adduced, including such statements provided in a modified or edited form; ii a skeleton argument which summarises the submissions which will be made and cites the authorities which will be relied upon, identifying any particular passages to be relied upon; iii a chronology of events; iv any other particulars or supplementary statements which may reasonably be required for the determination of the appeal; v any document or other material which the Tribunal may require and which it is in the power of that party to deliver; vi an estimate of the time which will be needed for any hearing; and vii a list of the witnesses he intends to call to give evidence at any hearing; d limit the length of oral submissions and the time allowed for the examination and cross-examination of witnesses; and e limit the number of expert witnesses to be heard on either side. 5 The Tribunal may, subject to any specific provisions of these Rules, specify time limits for steps to be taken in the proceedings and may extend any time limit. 6 Nothing in this rule may require the production of any document or other material which the party could not be compelled to produce on the trial of an action in a court of law in that part of the United Kingdom where the appeal is to be determined. 7 It shall be a condition of the supply of any information or material provided under this rule that any recipient of that information or material may use it only for the purposes of the appeal. 8 The power to give directions may be exercised in the absence of the parties. 9 Notice of any directions given under this rule shall be served on all the parties, and the Tribunal may, on the application of any party, set aside or vary such directions. Applications by relevant Minister 16 1 This rule applies in any case where the Tribunal proposes to– a give or vary any direction under rule 15 above or rule 18(2) below, b issue a summons under rule 20 below, or c certify or publish a determination under rule 27 below. 2 Before the Tribunal proceeds as proposed in any case to which this rule applies, it must first notify the relevant Minister of the proposal. 3 If the relevant Minister considers that proceeding as proposed by the Tribunal would cause information to be disclosed contrary to the interests of national security, he may make an application to the Tribunal requesting it to reconsider the proposal or reconsider it to any extent. 4 An application by the relevant Minister under paragraph (3) above must be made within 14 days of receipt of notification under paragraph (2), and the Tribunal must not proceed as proposed in any case to which this rule applies before that period has expired, otherwise than in accordance with rule 17 below, unless the relevant Minister has indicated that he does not object. 5 Where the relevant Minister makes an application under this rule, the Tribunal must not proceed as proposed otherwise than in accordance with rule 17 below. Determinations on relevant Minister’s objections and applications 17 1 Except where rule 11 above applies, the Tribunal shall determine whether to uphold any objection of the relevant Minister under rule 12 above, and any application under rule 16 above, in accordance with this rule. 2 Subject to paragraph (3) below, proceedings under this rule shall take place in the absence of the parties. 3 The relevant Minister (or a person authorised to act on his behalf), may attend any proceedings under this rule, whether or not he is a party to the appeal in question. 4 An objection under rule 12 above must be considered under this rule as a preliminary issue, and an application under rule 16 above may be considered as a preliminary issue or at the hearing of the substantive appeal. 5 Where, in the case of an objection under rule 12 above, the Tribunal is minded to overrule the relevant Minister’s objection, or to require him to provide a version of his notice in a form other than that in which he provided it under rule 12(3)(b) above, the Tribunal must invite the relevant Minister to make oral representations. 6 Where the Tribunal under paragraph (5) above overrules an objection by the relevant Minister under rule 12 above, or requires him to provide a version of his notice in a form other than that in which he provided it under rule 12(3)(b) above, the Tribunal shall not disclose, and the relevant Minister shall not be required to disclose, any material which was the subject of the unsuccessful objection if the relevant Minister chooses not to rely upon it in opposing the appeal. 7 Where, in the case of an objection under rule 12 above, the Tribunal upholds the relevant Minister’s objection and either– a approves the version of his notice provided under rule 12(3)(b); or b requires him to provide a version of his notice in a form other than that in which he provided it under rule 12(3)(b), rule 7(3) above applies to that version of the notice. Power to determine without a hearing 18 1 Without prejudice to rule 11 above, where either– a the parties so agree in writing, or b it appears to the Tribunal that the issues raised on the appeal have been determined on a previous appeal brought by the appellant on the basis of facts which did not materially differ from those to which the appeal relates and the Tribunal has given the parties an opportunity of making representations to the effect that the appeal ought not to be determined without a hearing, the Tribunal may determine an appeal, or any particular issue, without a hearing. 2 Before determining any matter under this rule, the Tribunal may, subject to rule 16 above, if it thinks fit direct any party to provide in writing further information about any matter relevant to the appeal within such time as the Tribunal may allow. Time and place of hearings 19 1 Except where rule 11 or 18 above applies, as soon as practicable after notice of appeal has been given, and with due regard to the convenience of the parties, the Tribunal shall appoint a time and place for a hearing of the appeal. 2 Except in relation to a hearing under rule 11(5) above, the proper officer shall send to each party, the Commissioner and the relevant Minister a notice informing him of the time and place of any hearing, which, unless the parties otherwise agree, shall not be earlier than 14 days after the date on which the notice is sent. 3 A notice to a party under this rule shall inform him of the effect of rule 22 below. 4 The Tribunal may– a postpone the time appointed for any hearing; b adjourn a hearing to such time as the Tribunal may determine; or c alter the place appointed for any hearing; and, if it exercises any of the above powers, it shall notify each person previously notified of that hearing under this rule or rule 11(6) above, and any person summoned under rule 20 below to attend as a witness at that hearing, of the revised arrangements. Summoning of witnesses 20 1 This rule is subject to rule 16 above. 2 Subject to paragraph (3) below, the Tribunal may by summons require any person in the United Kingdom to attend as a witness at a hearing of an appeal at such time and place as may be specified in the summons and, subject to rule 26(2) and (3) below, at the hearing to answer any questions or produce any documents in his custody or under his control which relate to any matter in question in the appeal. 3 No person shall be required to attend in obedience to a summons under paragraph (2) above unless he has been given at least 7 days' notice of the hearing or, if less than 7 days, he has informed the Tribunal that he accepts such notice as he has been given. 4 The Tribunal may upon the application of a person summoned under this rule set the summons aside. 5 A person who has attended a hearing as a witness in obedience to a summons shall be entitled to such sum as the Tribunal considers reasonable in respect of his attendance at, and his travelling to and from, the hearing; and where the summons was issued at the request of a party such sum shall be paid or tendered to him by that party. 6 In relation to proceedings before the Tribunal in Scotland, in this rule “ summons” means citation and the provisions of this rule are to be construed accordingly. Representation at a hearing 21 1 At any hearing by the Tribunal, other than a hearing under rule 11 above– a a party may, subject to rules 17(2) above and 23(3) below, conduct his case himself or may appear and be represented by any person whom he may appoint for the purpose, and b the relevant Minister may appear and be represented by any person whom he may appoint for the purpose. 2 At any hearing by the Tribunal under rule 11(5) above, the appellant may conduct his case himself or may appear and be represented by any person whom he may appoint for the purpose. Default of appearance at hearing 22 If, without furnishing the Tribunal with sufficient reason for his absence, a party fails to appear at a hearing, having been duly notified of the hearing, the Tribunal may, if that party is the appellant, dismiss the appeal or, in any case, hear and determine the appeal, or any particular issue, in the party’s absence and may make such order as to costs as it thinks fit. Hearings to be in private 23 1 All hearings by the Tribunal (including preliminary hearings) shall be in private unless the Tribunal, with the consent of the parties and the relevant Minister, directs that the hearing or any part of the hearing shall take place in public. 2 Where the Tribunal sits in private it may, with the consent of the parties and the relevant Minister, admit to a hearing such persons on such terms and conditions as it considers appropriate. 3 Where the Tribunal considers it necessary for any party other than the relevant Minister to be excluded from proceedings or any part of them in order to secure that information is not disclosed contrary to the interests of national security, it must– a direct accordingly, b inform the person excluded of its reasons, to the extent that it is possible to do so without disclosing information contrary to the interests of national security, and record those reasons in writing, and c inform the relevant Minister. 4 The relevant Minister, or a person authorised to act on his behalf, may attend any hearing, other than a hearing under rule 11 above, notwithstanding that it is in private. Conduct of proceedings at hearing 24 1 Subject to rules 22 and 23(3) above, the Tribunal shall at the hearing of an appeal give to each party and the relevant Minister an opportunity– a to address the Tribunal and to amplify orally written statements previously furnished under these Rules, to give evidence and to call witnesses, and to put questions to any person giving evidence before the Tribunal, and b to make representations on the evidence (if any) and on the subject matter of the appeal generally but, where evidence is taken, such opportunity shall not be given before the completion of the taking of evidence. 2 Except as provided by these Rules, the Tribunal shall conduct the proceedings in such manner as it considers appropriate in the circumstances for discharging its functions and shall so far as appears to it appropriate seek to avoid formality in its proceedings. Preliminary and incidental matters 25 As regards matters preliminary or incidental to an appeal the president may act for the Tribunal under rules 5(3), 8(2), 9, 13 to 15, 19(1) and (4)(a) and (c) and 20. Evidence 26 1 The Tribunal may receive in evidence any document or information notwithstanding that such document or information would be inadmissible in a court of law. 2 No person shall be compelled to give any evidence or produce any document which he could not be compelled to give or produce on the trial of an action in a court of law in that part of the United Kingdom where the appeal is to be determined. 3 The Tribunal may require oral evidence of a witness (including a party) to be given on oath or affirmation and for that purpose the president or the proper officer shall have power to administer oaths or take affirmations. Determination of appeal 27 1 As soon as practicable after the Tribunal has determined an appeal, the president shall certify in writing that determination and sign and date the certificate. 2 If and to the extent that it is possible to do so without disclosing information contrary to the interests of national security, and subject to rule 16 above, the certificate shall include– a any material finding of fact, and b the reasons for the decision. 3 The proper officer shall send a copy of the certificate to– a the parties, b the relevant Minister, and c the Commissioner. 4 Subject to rule 16 above, the Tribunal shall make arrangements for the publication of its determination but in doing so shall have regard to– a the desirability of safeguarding the privacy of data subjects and commercially sensitive information, and b the need to secure that information is not disclosed contrary to the interests of national security, and for those purposes may make any necessary amendments to the text of the certificate. 5 For the purposes of this rule (but without prejudice to it generally), the disclosure of information is to be regarded as contrary to the interests of national security if it would indicate the existence or otherwise of any material. Costs 28 1 In any appeal before the Tribunal, including one withdrawn under rule 13 above, the Tribunal may make an order awarding costs– a in the case of an appeal under regulation 32(4) of the Regulations– i against the appellant and in favour of the relevant Minister where it considers that the appeal was manifestly unreasonable; ii against the relevant Minister and in favour of the appellant where it allows the appeal and quashes the disputed certification, or does so to any extent; b in the case of an appeal under regulation 32(6) of the Regulations– i against the appellant and in favour of any other party where it dismisses the appeal or dismisses it to any extent; ii in favour of the appellant and against any other party where it allows the appeal or allows it to any extent; and c where it considers that a party has been responsible for frivolous, vexatious, improper or unreasonable action, or for any failure to comply with a direction or any delay which with diligence could have been avoided, against that party and in favour of the other. 2 The Tribunal shall not make an order under paragraph (1) above awarding costs against a party without first giving that party an opportunity of making representations against the making of the order. 3 An order under paragraph (1) above may be to the party or parties in question to pay to the other party or parties either a specified sum in respect of the costs incurred by that other party or parties in connection with the proceedings or the whole or part of such costs as taxed (if not otherwise agreed). 4 Any costs required by an order under this rule to be taxed may be taxed in the county court according to such of the scales prescribed by the county court rules for proceedings in the county court as shall be directed by the order. 5 In relation to proceedings before the Tribunal in Scotland, for the purposes of the application of paragraph (4) above, for the reference to the county court and the county court rules there shall be substituted references to the sheriff court and the sheriff court rules and for the reference to proceedings there shall be substituted a reference to civil proceedings. Irregularities 29 1 Any irregularity resulting from failure to comply with any provision of these Rules or of any direction of the Tribunal before the Tribunal has reached its decision shall not of itself render the proceedings void, but the Tribunal may, and shall if it considers that any person may have been prejudiced by that irregularity, give such directions or take such steps as it thinks fit before reaching its decision to cure or waive the irregularity, whether by amendment of any document, the giving of notice or otherwise. 2 Clerical mistakes in any document recording or certifying a direction, decision or determination of the Tribunal or president, or errors arising in such a document from an accidental slip or omission, may at any time be corrected by the president by certificate signed by him. Notices etc. 30 1 Any notice or other document required or authorised by these Rules to be served on or sent to any person or authority may be sent by post in a registered letter or by the recorded delivery service– a in the case of the Tribunal, to the proper officer of the Tribunal; b in the case of an appellant or a respondent telecommunications provider, to him at his address for service under these Rules; c in the case of the relevant Minister or the Commissioner, to him at his office. 2 An appellant or respondent telecommunications provider may at any time by notice to the Tribunal change his address for service under these Rules.
