"The Supreme Court of Canada struck down Friday warrantless wiretap powers that police have in cases of emergency. ... Ruling in a 2006 British Columbia kidnapping case, the country’s top court said a 1993 provision of the Criminal Code is unconstitutional because there is no accountability or oversight for the warrantless searches, either to the person wiretapped or in reports to Parliament. The unanimous ruling was written by rookie judges Michael Moldaver and Andromache Karakatsanis. The case revolves around police intercepting the calls of the family of Peter Li, the kidnap victim."
