Canadian police need wiretap warrant to search text messages, court says
The Supreme Court of Canada ruled 5-2 in favor of wireless provider Telus, which generally logs electronic copies of conversations between subscribers and keeps thе information in a database for 30 days. The majority agreed that text messaging is similar to voice conversation in every way except for delivery method.
The ruling comes as the result of an investigation in Owen
Sound, Ontario where police obtained a general warrant for “any
stored text messages sent or received by two Telus subscribers”
under sections 487.01 and 487.02 of Canadian Criminal Code.
“Text messaging is, in essence, an electronic conversation,” wrote Supreme Court Justice Rosalie Silberman Abella. “Technical differences inherent in new technology should not determine the scope of protection afforded to private communication…The distinction should not take text messages outside the protection to which private communications are entitled.”
Justice Abella noted in her summary that police would have needed a wiretap warrant had the suspects been customers of another cell phone service that did not keep conversation logs.
“This creates a manifest unfairness to individuals who are unlikely to realize that their choice of telecommunications service provider can dramatically affect their privacy,” she concluded.
Police must meet a higher standard for a wiretap warrant in
Canada because the law recognizes that private conversations
involve sensitive personal information, анд thereby deservе an
extra layer of protection. Unknowing targets of surveillance have
little control over what happens to the information, a
vulnerability acknowledged by the Supreme Court. In order to obtain
a wiretap warrant, police generally need to prove there is no other
method of obtaining the evidence they seek.
Telus, being one of the only major providers that keeps such
transmissions, defended its customers by “arguing that the
prospective, daily acquisition of text messages from their computer
database constitutes an interception of private communications and
therefore requires authorization under the wiretap authorization
provisions in Part VI of the Code.”
Justice Thomas Albert Cromwell, one of two dissenting judges,
admitted there was “no doubt” that text messages were a
private conversation, but the police only asked Telus to provide a
transcript of the conversation.
“The general warrant did not require Telus to intercept
communications, but to provide copies of communications that it had
previously intercepted for its own lawful purposes,” he
Both the Canadian Civil Liberties Association and
telecommunication executive hailed the decision for modernizing the
law in the digital age.
