Part 8: Oversight arrangements Chapter 1: Investigatory Powers Commissioner and other Judicial Commissioners Section 231: Error reporting
This section provides for a process through which people can be informed of serious relevant error in the use of investigatory powers that relates to them. A relevant error means an error made by a public authority in complying with any requirement over which the Investigatory Powers Commissioner has oversight.
	The IPC must inform the person affected by a relevant error if the error is serious and if it is in the public interest for the person to be informed. An error can only be considered serious if it has caused significant prejudice or harm to the person concerned. In deciding whether informing the person is in the public interest, the Commissioner must balance on one hand the seriousness of the error and the impact on the person concerned, and on the other hand the extent to which disclosing the error would be contrary to the public interest or would be prejudicial to national security, the prevention and detection of serious crime, the economic well-being of the UK, or the ability of the intelligence agencies to carry out their functions.
	If the IPC decides that the person should be informed, that person must also be informed of any right they have to bring a claim in the Investigatory Powers Tribunal. The person must also be provided with the details necessary to bring such a claim, to the extent that disclosing information is in the public interest.
	The IPC’s annual report (see section 234) must include details regarding errors, including the number of errors the Commissioner becomes aware of, and the number of times a person has been informed of an error.
