Judicial function of the House of Lords

11.5Since the establishment of the Supreme Court,1 the sole remaining judicial function of the House of Lords is in respect of peerage claims.

In discharging its role in determining peerage claims, the House remains responsible, in certain circumstances, for determining individuals' rights and liabilities under the law.2

The House's jurisdiction in impeachments by the Commons has fallen into disuse.3
