weiler had an influence on the formation of the 1982 canadian constitution. an article weiler wrote for the mcgill law journal recommended inserting a non obstante clause in the canadian charter of rights and freedoms. this would allow an individual province to pass a law in violation of some charter provisions. this concept was shared with jim matkin, british columbia deputy minister of inter governmental affairs, who shared this with other provinces in a no-author text during interprovincial negotiations toward constitutional change in canada. during the kitchen accord this concept reappeared and became one of the compromises that lead to a patriated canadian constitution.
