The third edition of Parliament and the Law presents a timely and valuable resource covering recent developments. Brexit, the #MeToo movement, and the COVID-19 pandemic all presented Parliament with a series of challenges. This edition includes new chapters on Brexit, legislation and scrutiny, the restoration and renewal of the Palace of Westminster treaty scrutiny, votes of confidence and the Fixed Term Parliament Act, and the financing of Parliament. This is a multi-disciplinary work authored by lawyers, political scientists, parliamentary officials, and practitioners and is supported by the Study of Parliament Group (SPG).
