R v Grant is a leading decision of the Supreme Court of Canada on section 9, section 10, and section 24(2) of the Canadian Charter of Rights and Freedoms. The Court created a number of factors to consider when determining whether a person had been detained for the purpose of sections 9 and 10 of the Charter. The Court also created a new test for determining whether evidence obtained by a Charter breach should be excluded under section 24(2) of the Charter, replacing the Collins test.
