In December the Supreme Court of Canada released their decision in R v Reeves. This decision considered what expectation of privacy an individual has in a shared digital device, such as a shared computer or tablet. The Court found that a third-party, even one who has access to the shared device, cannot unilaterally consent to a police search and seizure of the device.
In Reeves, the accused's estranged common-law wife had consented to the police seizing and searching a shared device in order to look for evidence of possession of child pornography. The accused was facing a domestic assault charge at the time and had conditions preventing him from being at the residence during the time his ex-partner consented to the seizure.
The Supreme Court affirmed the test that a Court must apply in order to determine whether an individual has a reasonable expectation of privacy in a shared digital device. The majority also confirmed that control over or ownership of the computing device, while relevant, is not determinative of whether a subjective expectation of privacy is objectively reasonable.
