5.  On 23 December 1990, the applicant was arrested for drunkenness and taken to Hammersmith Police Station. He was held overnight in a cell shared by another detainee, Patrick Quinn. The next day, Mr Quinn was found dead with severe injuries. The applicant was charged with his murder. The applicant alleged that the police had framed him for the murder in order to cover up their own wrongdoing. In September 1991, the applicant was found guilty of the murder of Mr Quinn and was sentenced to life imprisonment. In February 1993, his conviction was overturned on appeal. At a first retrial, one of the police officers, a key prosecution witness, failed to appear. He was subsequently declared mentally unstable and was withdrawn from the proceedings. Following a second retrial, the applicant was convicted in 1994 of manslaughter and sentenced to nine years' imprisonment. The case was controversial in the United Kingdom on account of missing and conflicting police evidence which led some – including a number of Members of Parliament – to question the safety of the applicant's conviction. 6.  In 1996, the applicant was released from prison. Following his release, he became active in campaigning against miscarriages of justice generally. He subsequently started a removal business called Small Moves, undertaking small moves and van hire in London. Although his business did well at the beginning, he subsequently began to experience interference with his business telephone calls. He alleged that local calls to his telephone were not being put through to him and that he was receiving a number of time-wasting hoax calls. The applicant suspected that this was because his mail, telephone and email communications were being intercepted. As a result of the interference, the applicant's business began to suffer. 7.  The applicant believed that the interception of his communications was directly linked to his high profile case and his subsequent involvement in campaigning against miscarriages of justice. He alleged that the police and security services were continually and unlawfully renewing an interception warrant – originally authorised for the criminal proceedings against him – in order to intimidate him and undermine his business activities. 8.  On 10 July 2000 the applicant made subject access requests to MI5 and GCHQ (the United Kingdom's intelligence agencies responsible for national security) under the Data Protection Act 1998 (“DPA” – see paragraphs 21 to 22 below). The object of the requests was to discover whether information about him was being processed by the agencies and to obtain access to the content of the information. Both requests were refused on the basis that the information requested was exempt from the disclosure requirements of the 1998 Act on the grounds of national security under certificates issued by the Secretary of State on 22 July 2000 (MI5) and 30 July 2000 (GCHQ). 9.  On 6 July 2001 the applicant lodged two complaints with the Investigatory Powers Tribunal (“IPT”). First, the applicant complained under sections 65(2)(b) and 65(4) of the Regulation of Investigatory Powers Act 2000 (“RIPA” – see paragraphs 25 to 80 below) that his communications were being intercepted in “challengeable circumstances”, within the meaning of section 65(7) RIPA (i.e. under an interception warrant or in circumstances in which there ought to have been an interception warrant or where consideration ought to have been given to obtaining an interception warrant). Second, the applicant complained under sections 6(1) and 7(1) of the Human Rights Act 1998 (“HRA”) and section 65(2)(a) RIPA that there was an unlawful interference with his rights under Article 8 of the Convention. 10.  The applicant's Grounds of Claim and Complaint outlined the grounds for bringing the proceedings as follows:
“4(a) That the authorities' conduct was, and is, incompatible with his rights under Article 8 of the Convention and a violation of equivalent rights of his at common law. Such conduct is unlawful as a result of HRA s. 6(1) and forms the basis for a complaint under RIPA s. 65.
(b) To the extent any such conduct purports to have the authority of a warrant issued or renewed under RIPA Part I or the corresponding predecessor provisions of the Interception of Communications Act 1985 (“IOCA”), the issue and renewal of that warrant, as well as the conduct itself, has at all times lacked the necessary justification, whether under the express provisions of RIPA Part I (or IOCA), Article 8(2) of the Convention, or the general law.
(c) Moreover the authorities' conduct was and is unlawful because in breach of the requirements of the Data Protection Act 1998 (“DPA”). Conduct in breach of those requirements takes place in challengeable circumstances under RIPA s. 65(4) and (7) and is also incompatible with the Complainant's rights under Article 8 of the Convention. 5. In addition, the Complainant relies in these proceedings on his right to a fair hearing under Article 6(1) of the Convention. In light of that right, the Complainant makes certain submissions about the way in which these proceedings ought to be conducted ...” 11.  The applicant requested specific directions regarding the conduct of the proceedings in order to ensure the protection of his Convention rights under Article 6 § 1. In particular, he requested that his arguments and evidence be presented at an oral hearing; that all hearings be conducted in public; that there be mutual disclosure and inspection between the parties of all witness statements and evidence upon which parties sought to rely and exchange of skeleton arguments in relation to planned legal submissions; that evidence of each party be heard in the presence of the other party or their legal representatives, with oral evidence being open to cross-examination by the other party; that any opinion received from a Commissioner be disclosed to the parties, who would have the opportunity to make oral representations in light of it; that each party be able to apply for a derogation from any of the above in relation to a particular piece of evidence; and that, following its final determination, the IPT state its findings and give reasons for its conclusions on each relevant issue. He argued that to the extent that the IPT's rules of procedure (see paragraphs 84 to 87 below) prevented the directions sought, they were incompatible with his right to a fair hearing. 12.  The Grounds of Claim and Complaint referred to the applicant's belief that his communications were being intercepted and that any warrant in place was being continually renewed. 13.  Paragraph 13 of the Grounds of Claim and Complaint noted:
“So far as the proceedings are brought in reliance on HRA s. 7(1)(a) or (b), the Complainant submits that:
(a) The interception, and retention or other processing of intercept product, by any of the Respondents amounts to an interference with the Complainant's right to respect for private life and correspondence protected by Article 8(1) of the Convention;
(b) The interception and processing have at no time been in accordance with the law as required by Article 8(2);
(c) The interception and its purported authorisation (if any), and processing, have at no time been justified as necessary in a democratic society as required by Article 8(2).” 14.  Paragraph 14 of the Grounds of Claim and Complaint expanded on the applicant's submissions:
“In particular, the Complainant submits that:
(a) the proper inference from the circumstances described by the Complainant, amplified by the refusal of the [authorities] to deny the activities alleged, is that it is established on the balance of probabilities that the interception and processing took place. At minimum there is a reasonable likelihood that interception and processing ... has taken place and continues to take place (Hewitt and Harman v. UK, 12175/86, EComHR Report 9.5.89, paras. 26-32).
(b) The interception is not in accordance with the law so far as involving a breach of any requirement of the DPA (including the Data Protection Principles) ...
(c) The complainant poses no risk to national security nor in his case could any other ground for authorising interception of his communications reasonably be considered to exist. It cannot be said that interception of his communications has at any material time been a necessary or proportionate interference ... with his rights under Article 8(1).” 15.  As to remedies, the Grounds of Claim and Complaint noted the following:
“17. If the Tribunal finds that the Complainant succeeds on the claim or complaint, it is asked to make ... :
(a) a final order prohibiting each Respondent from intercepting any communication by the Complainant ... or retaining or otherwise processing the product of any such interception, except on the grounds, and subject to the procedure, provided for by RIPA Part I;
(b) an order ... quashing or cancelling any warrant or authorisation relating to any such interception;
(c) an order requiring the destruction of any product of such interception ...
(d) an award of compensation ... and/or damages ... for the loss and damage sustained by the Complainant in consequence of the matters complained of (including economic loss resulting from interference with his business communications).” 16.  On 23 January 2003, the IPT, presided over by Lord Justice Mummery, issued a joint Ruling on Preliminary Issues of Law in the applicant's case together with a case involving a complaint by British-Irish Rights Watch and others in which a similar challenge to the IPT's Rules was made (see paragraphs 84 to 87 below). 17.  On 9 December 2004, the IPT, again presided over by Lord Justice Mummery, issued a second ruling on preliminary issues of law in the applicant's case. In the introduction to its ruling, the IPT summarised the case before it as follows:
“1. On 6 July 2001 the Complainant made (a) a complaint to the Tribunal under the Regulation of Investigatory Powers Act ... and (b) a claim under the Human Rights Act 1998 ... in respect of alleged ongoing interception by one or more of the respondent agencies (the Security Service, GCHQ and the Commissioner of Police for the Metropolis) over a period dating back to June 1996 ... 2. The Complainant also alleges harassment, intrusive surveillance, interference with property, removal of documents, interference with a web site and e-mails and interception of privileged communications by the respondent agencies. 3. The Complainant seeks a final order prohibiting the agencies from intercepting any communication by him in the course of its transmission by means of a telecommunications system or retaining or otherwise processing the product of any such interception except on the grounds and subject to the procedure provided by RIPA Part I. 4. He also seeks an order requiring the destruction of any product of such interception held by each respondent, whether or not obtained pursuant to any warrant or authorisation; and an award of compensation under s 67(7) RIPA and/or damages sustained by the Complainant in consequence of the matters complained of.” 18.  The ruling dealt with a number of matters relating to the extent of its jurisdiction in respect of the applicant's complaints relating to conduct prior to the entry into force of RIPA. 19.  Following its ruling of 9 December 2004, the IPT proceeded to examine the applicant's specific complaints in private. 20.  On 17 January 2005, the IPT notified the applicant that no determination had been made in his favour in respect of his complaints. This meant either that there had been no interception or that any interception which took place was lawful.
