Wolf: The British Parliament lacks unilateral power to remove the monarch or abolish the monarchy since the monarch can deny such an act royal assent, which would effectively ensure such an act doesn’t become legally effective.
While that may be technically true, it isn’t on a practical level. I’m pretty sure James II did not assent to the ruling of Parliament that he had abdicated the throne, and yet, at least in England, it was considered effective.
