R. v. Bartle, 3 S.C.R. 173 is a leading Supreme Court of Canada decision on the right to retain and instruct counsel under section 10(b) of the Canadian Charter of Rights and Freedoms. The Court held that a police officer is required to hold off on their investigation upon arresting an individual until they have been informed of their rights and given sufficient information and access to contact a private lawyer or duty counsel. The case applied the earlier Supreme Court of Canada case, R. v. Brydges. The judgment was released with three other decisions: R. v. Pozniak, R. v. Harper, R. v. Matheson, and R. v. Prosper.
