A more thorough explanation:

A commission of delegates was a legal process in which a person, usually a lord, bishop, or judge, was appointed to sit with several other appointees to hear an appeal of an ecclesiastical judgment in the Court of Chancery.

For example, if a person was unhappy with a decision made by the Church, they could appeal to the Court of Chancery. The commission of delegates would then be appointed to hear the appeal and make a decision.

This commission was abolished in 1832, and its functions were transferred to the Judicial Committee of the Privy Council.

The commission of delegates was an important part of the legal system in England during the 18th and 19th centuries. It ensured that appeals were heard fairly and impartially, and that justice was served.
