and privileges of prisoners with regard to visits and correspondence, was revised and published with effect from April 1989. The new version of the standing order incorporates further guidance issued in 1987 and embodies additional safeguards for prisoners as against its 1981 predecessor (on whict CCPR/C/58/Add.6 page 53 see the second report, paras. 65-66), in particular abolition of the simultaneous ventilation rule and incorporation of procedures designed to guarantee the privacy of inmates' correspondence with their legal advisers. The Scottish and Northern Ireland standing orders are about to be revised and will incorporate similar amendments to those outlined above, although guidance on these matters has already been issued. Interception 231. The Interception of Communications Act 1985, which came into force on 10 April 1986, created a new offence of unlawful interception; put on a statutory basis the procedure for obtaining interception warrants; and required that proper arrangements be made for safeguarding intercepted material, in particular to ensure that the disclosure of such material be kept to the minimum necessary for the purposes described in the Act. The Act provides a means of redress for members of the public who believe that their communications are being intercepted under a warrant: a tribunal with powers including the quashing of warrants and the ability to direct the Secretary of State to pay compensation. The Act also provides for an independent commissioner to review the working of the Act and to report annually to the Prime Minister; this report is to be laid before each House of Parliament and made available to the public. 232. Section 1 of the Act provides for penalties, on conviction on indictment, of imprisonment for a term not exceeding two years or an unlimited fine or both.
