In R v. Gladue the Court interpreted the meaning of s.718.2(e) of the Criminal Code. The section states that when imposing a sentence a court should look at all alternatives to custody paying particular attention to the circumstances of Aboriginal people. ALST intervened in support of the Aboriginal person who was seeking the benefit of the section. This decision by the Supreme Court led to the creation of the Gladue Court - an initiative that ALST has been very much a part of.
R. v. Ipeelee, 2012 SCC 13,  1 S.C.R. 433
R v Ipeelee solidified Gladue as good, essential law. It confirmed that the Court remained committed to the principles it set out in the 1999 decision of R. v. Gladue with respect to addressing the causes of Aboriginal over-representation in prison through the sentencing process.
