who decides whether a law follows the constitution or not
Canadian constitutional law Under the authority of section 52(1) of the Constitution Act, 1982, courts may review all matters of law. Accordingly, the courts have a broad reaching scope of competence. Constitutional issues come before the court through disputes between parties as well as through reference questions. The court has the discretion to hear any Constitutional issues as long as there is a sufficient legal component.[nb 2] The US constitutional political questions doctrine was rejected and so a political dimension to the issue does not bar it from court.[nb 3]
