James I did not concede that he could not rule by prerogative and attempted to place all of his proclamations on a constitutional footing, having them published in a book as if they were statutes. He went to argue that proclamations were necessary to "apply speedy, proper, and convenient remedies ... in matters so variable and irregular in their nature, as are not provided for by Law, nor can fitly fall under the certain rule of a law".
17th century In future English history, the issue of proclamations would form part of the many grievances and issues in dispute between both James I and Charles I and their parliaments before the English Civil War. MPs would go on to cite Coke's judgment in the
Case of Proclamations to support their arguments against the arbitrary use of royal power in the years up to 1641. Whilst disputed, the case is seen by some historians and jurists as influential in the development of the concept of
judicial review in
English common law. However, the issue about the extent of the royal prerogative was not properly resolved until the
Bill of Rights 1689 "established that the powers of the Crown were subject to law, and there were no powers of the Crown which could not be taken away or controlled by statute".
Exiting the European Union Over 400 years on, the Case of Proclamations continues to affect the constitutional law of the UK. It was cited in 2017 by a
divisional court of the High Court in its landmark
judicial review decision,
R (Miller) v Secretary of State for Exiting the European Union, concerning whether the UK government had the power, under the Crown's
foreign affairs prerogative, to serve a notice triggering
Brexit following the "leave" vote in the 2016
EU Referendum. The divisional court cited two principles from the Case of Proclamations: • that "the King by his proclamation or other ways cannot change any part of the common law, or statute law, or the customs of the realm"; and • that "the King hath no prerogative, but that which the law of the land allows him". The divisional court unanimously rejected the government's argument in robust terms (which were subsequently upheld 8-3 (Neuberger, Hale, Mance, Kerr, Clarke, Sumption, Wilson, Hodge) by an 11-justice panel (Reed, Carnwath and Hughes dissenting) of the
Supreme Court). The court concluded that the government did not have the right to rely on
royal prerogative to serve a notice pursuant to Article 50 of the
Treaty on European Union, triggering the formal process for the UK to leave the EU. The court added that, because Brexit would directly affect substantive legal rights under UK domestic law, only Parliament could decide whether to serve such a notice.
Prorogation of Parliament The Case of Proclamations was again cited in the 2019 Supreme Court case
R (Miller) v The Prime Minister and Cherry v Advocate General for Scotland. ==See also==
