"Philippon refused to divulge the passcode for his cell phone, preventing border services officers from their duties," Canada Border Services Agency said in an email.The agency insists that the Customs Act authorizes its officers to examine "all goods and conveyances including electronic devices, such as cell phones and laptops."But, according to legal experts, the issue of whether a traveler must reveal the password for an electronic device at a border crossing has not been tested in court. "(It's) one thing for them to inspect it, another thing for them to compel you to help them," Rob Currie, director of the Law and Technology Institute at Dalhousie University, told public broadcaster CBC.Philippon is scheduled to appear in court on May 12.
