Were The Intolerable Acts of 1774 unconstitutional?

Under the Constitution of the United Kingdom, the Intolerable (Coercive) Acts of 1774 were not unconstitutional. In fact, it is clearly stipulated in the Constitution of the United Kingdom that "No Act of Parliament can be unconstitutional, for the law of the land knows not the Word or the idea." The Intolerable Acts also cannot have been considered unconstitutional under the United States Constitution as it was not yet established at the time.
