9. The House of Commons
This chapter explores the membership and functions of the House of Commons. The Commons' membership consists of Members of Parliament (MPs) who are democratically elected by the public to represent their interests in Parliament. The key functions of the House of Commons include sustaining the government; legislating and scrutinising government actions; authorising taxes and voting for supply to provide the government with the finances it needs to run the UK; facilitating a credible opposition; and ensuring that the voices of citizens are heard. The chapter then considers the operation of Parliamentary privilege. Parliament needs parliamentary privilege to conduct its core business effectively, independently, and without fear of outside interference, and to protect everything said or done in the transaction of parliamentary business. Indeed, Parliament is self-regulating and, as a sovereign body, operates outside the jurisdiction of the courts except for the criminal law.
