After the King had been moved to London, the Rump Parliament passed a Bill setting up what was described as a "High Court of Justice in order to try Charles I for high treason" in the name of the people of England. The bill initially nominated 3 judges and 150 commissioners, but following opposition in the House of Lords, the judges and members of the Lords were removed. When the trial began, there were 135 commissioners who were empowered to try the King, but only 68 would ever sit in judgement. The Solicitor General John Cook was appointed prosecutor.
