Canadian Constitutional Law/Amending the Constitution

Before 1982, the only way to amend the written Constitution of Canada was to ask the Parliament of the United Kingdom in London to pass legislation. Even upon the passage of the [Statute of Westminster, 1931, when the United Kingdom Parliament stated that its laws no longer applied to Canada, the U.K. Parliament retained the right to amend the Constitution of Canada through section 4 of the Statute. The Constitution Act, 1982, was therefore made law by a statute of the United Kingdom (called the Canada Act).
