What the Tribunal can Investigate
The Tribunal can investigate anything you believe has taken place against you, your property or communications, as long as it relates to a power held by the organisation you are complaining about, under the Regulation of Investigatory Powers Act.
The Tribunal can investigate complaints about any alleged conduct by or on behalf of the Intelligence Services - Security Service (sometimes called MI5), the Secret Intelligence Service (sometimes called MI6) and GCHQ (Government Communications Headquarters). Because the Tribunal is the only appropriate place you can complain about the Intelligence Services, the scope of conduct it can investigate concerning them, is much broader than it is with regard to the other organisations under its jurisdiction.
