Judicial functions of the House of Lords

Whilst the House of Lords of the United Kingdom is the upper chamber of Parliament and has government ministers, for many centuries it had a judicial function.

Replying to Skinner's petition, the East India Company objected that the case was one of first instance, and that the Lords therefore should not have accepted it.

Though lawyers argued that the House could intervene only after the lower courts had failed to remedy the case, the Lords decided in Skinner's favour in 1668.

The East India Company then petitioned the House of Commons, arguing that the acceptance of a case in the first instance by the Lords was "unusual" and "extraordinary".

The acts were silent on appeals to the House of Lords, unless they be deemed of 'like nature' to Westminster Hall, in which case it would be banned.

[2] Appeal Committees normally convened fifteen to twenty times per year, and their members were selected by the Principal Clerk of the Judicial Office of the House of Lords.

[citation needed] The determination of each Appellate Committee was normally final, but the House of Lords (in common with the Court of Appeal and High Court of England and Wales) retained an inherent jurisdiction to reconsider any of its previous decisions; this includes the ability to vacate that decision and make a new one.

[7] The tradition that appeals should be heard by Appellate Committees and not by the full House of Lords developed relatively late, after the Second World War.

In an appeal in a patent infringement case, it took almost seven days to go through opening argument because counsel for the appellant was expected to read out loud all relevant portions of the Court of Appeal opinion and the trial court record (all of which had already been provided in advance to the Committee in hard copy format), while interpolating extensive comment and argument, and digressing into lengthy exchanges with the Committee members.

"[10] This was a signal that all barristers, solicitors, and others present for the hearing were expected to leave the room immediately, so the Committee could begin its deliberations.

[13] The House of Lords' staff would notify counsel that judgment was imminent about five or six days before the relevant sitting, and provide advance copies of the Committee's written report (the Lords' written speeches) and the House minutes (in plain English, a script of the pro forma questions to be raised and voted upon) to counsel when they arrived for the sitting.

[12] Thus, he would repeatedly move away from the Woolsack to make a motion in his capacity as a member of the Appellate Committee, and then move back to the Woolsack in his capacity as the presiding officer of the House of Lords to recite the traditional formula which meant that a majority had voted for the motion: "As many as are of that opinion will say 'Content', to the contrary, 'Not Content'.

No Parliamentary business is conducted during that time, except the taking of oaths of allegiance and the election of a Speaker by the House of Commons.

The Judicial Committee's domestic jurisdiction was very limited, hearing only cases on the competency of the devolved legislatures in Scotland, Northern Ireland, and Wales.

The 'devolution issues' were transferred from the Privy Council to the Supreme Court of the United Kingdom; however, the former continues to hear Commonwealth appeals.

Peeresses in their own right and wives or widows of peers were also entitled to trial in such a court, though they were never members of the House of Lords.

He as president was sole judge of questions of law or procedure, but a jury of Lords Triers determined the verdict.

In any event, the Lords relied almost exclusively on the advice tendered by royal justices, who were the same people presiding over standard criminal cases.

In 1936, a year after the de Clifford trial, the Lords voted to abolish the privilege but the legislation was not given time in the Commons by the government before the session ended.

The novel Clouds of Witness (1926) by Dorothy L. Sayers depicts in the House of Lords the fictional trial of a duke who is accused of murder.

The UK constitutional institutions since early Victorian Britain have been careful to uphold a Diceyan emphasis on separation of powers (finalised with the Lord Chancellor's ending of his judicial office thwarted by a change of government in the 1870s, which that took place in the 2000s).

During the reign of the Stuarts, impeachment was revived; Parliament used it as a tool against the king's ministers during a time when it felt it needed to resist the tyranny of the Crown.

Such claims and disputes were in early centuries a matter for the monarch alone; Erskine and May states (2019) the House is regarded as guardian of its own privileges and membership.

The Lords later came close to breaching this convention a decade later, when the House was considering the case of Daniel O'Connell, an Irish politician.

They served on the Judicial Committee of the Privy Council, highest court of appeal in certain cases such as from some Commonwealth countries.

Normally, only the Law Lords on the Appellate Committee who were deciding the case voted when the House gave judgment.

After the rebellion of one of the Lord High Stewards, the position was forfeited and re-granted to Edmund Crouchback, but it later merged in the Crown.

Once the trial or coronation concluded, the Lord High Steward would break his white staff of office, thereby symbolising the end of his service in that position.

In hearing such claims it sits with three current holders of high judicial office, who are granted the same speaking and voting rights as members of the Committee.

Part 3 of the Constitutional Reform Act 2005, which came into force on 1 October 2009, abolished the appellate jurisdiction of the House of Lords, and transferred it to a new body, the Supreme Court of the United Kingdom.
