Covert activities
Part II of the RIPA and RIP(S)A put covert surveillance on a statutory basis enabling the public authorities identified in the legislation, to carry out such operations without breaching human rights.
They identify three categories of covert activity:
1 Intrusive surveillance
This is covert and carried out in relation to anything taking place on any residential premises or in any private vehicle. It involves a person on the premises or in the vehicle, or is carried out by a surveillance device. Except in cases of urgency, it requires a Commissioner's approval to be notified to the authorising officer before it can take effect. The power is available to the same law enforcement agencies as under the 1997 Act.
2 Directed surveillance
This is covert but not intrusive (and not an immediate response to events) but undertaken for a specific investigation or operation in a way likely to obtain private information about a person. It must be necessary and proportionate to what it seeks to achieve and may be used by the wide range of authorities identified in the legislation.
3 Covert Human Intelligence Sources
(CHIS)
The use or conduct of someone who establishes or maintains a personal or other relationship with a person for the covert purpose of obtaining information. The authorising officer must be satisfied that the authorisation is necessary, that the conduct authorised is proportionate to what is sought to be achieved and that arrangements for the overall management and control of the individual are in force. CHIS may be used by the wide range of authorities identified in the legislation.
Authorisations for directed surveillance and CHIS do not have to be notified to Commissioners but must be available for review when Commissioners, Assistant Commissioners and Inspectors visit the various authorities.
Encryption
Part III of RIPA covering Protected Electronic Information (Encryption) came into force on 1st October 2007 under SI 2007/2200. All public authorities should consult with the National Technical Assistance Centre at the earliest opportunity when considering exercising the powers in Part III of RIPA.
