Welcome to the Investigatory Powers Tribunal website

The Tribunal is a judicial body which operates independently of government to provide a right of redress for anyone who believes they have been a victim of unlawful action by a public authority using covert investigative techniques. The Tribunal is also the appropriate forum to consider complaints about any conduct by or on behalf of the UK Intelligence Community, MI5, SIS and GCHQ, as well as claims alleging the infringement of human rights by those agencies. The Tribunal has a UK wide jurisdiction and there are no costs associated with making a complaint to the Tribunal.

The Investigatory Powers Act 2016 strengthened the provisions governing the Tribunal by providing a new right of appeal from decisions and determinations of the Tribunal in circumstances where there is a point of law that raises an important point of principle or practice, or where there is some other compelling reason for allowing an appeal.

As the remit of the Tribunal is to deal with covert techniques and matters of national security, complainants are not required to provide evidence to support their complaint or Human Rights Act Claim. Instead they are asked to specify what activity they know or believe has taken place. The Tribunal is under a duty both to investigate and to determine valid complaints and public authorities are under a duty to provide the Tribunal with all documents and information the Tribunal may require to assist in that investigation. Nothing can be held back from the Tribunal for reasons of secrecy or national security. To counter this, and to protect sensitive information, the Tribunal may not disclose to the complainant anything which might compromise national security or the prevention and detection of serious crime, the economic well-being of the United Kingdom or the continued discharge of the functions of any of the intelligence services. However, wherever possible, and subject to this limitation, the Tribunal will provide findings of fact or a summary of the determination.
