Courts continue to grapple with the apparently difficult issue of searching cellular phones incident to arrest. In one of the most recent rulings, Boswell J seems to forge a somewhat new and much more restrictive approach to the issue: R v Liew,2012 ONSC 1826. A curious ruling given the recent comments of the Court of Appeal in R v Manley, 2011 ONCA 128.
A nice summary of Liew and commentary can be found on Westlaw Canada's CriminalSource's newest newsletter: Police Powers Newsletter 2012-01.
In brief, Liew was arrested on grounds that he was importing cocaine. A search incident to arrest revealed a Sony Erikson cell phone. The officer decided search the phone incident to arrest. The stated purpose for this search was to find "immediate phone calls and immediate texts" [para 15]. The officer did find some recent phone calls. The search of the phone lasted approximately 7 minutes [para 17].
