Definition
The Court of the Lord High Steward was an English tribunal convened exclusively for the trial of peers of the realm charged with treason, felony, or misprision of treason or felony. It was not a standing court but a temporary one, assembled only when a peer faced criminal prosecution during a parliamentary recess. When Parliament was sitting, a peer's trial proceeded instead before the House of Lords in its judicial capacity; it was only outside of a parliamentary session that the Lord High Steward's court was summoned.
The Lord High Steward, a great officer of state whose office was ordinarily kept vacant and filled only for ceremonial or judicial occasions, presided over the tribunal. When the court sat, a select number of peers were summoned to serve as triers — in effect, the jury — though the composition rules differed from ordinary jury practice.
The court had no civil jurisdiction and no role in appeals. Its function was narrow and specific: the criminal trial of members of the peerage when Parliament was not in session.

Common Confusion
Researchers sometimes conflate the Court of the Lord High Steward with the trial of peers before the House of Lords sitting as a court. The two were legally distinct. The House of Lords in its judicial capacity tried peers when Parliament was assembled; the Court of the Lord High Steward was the alternative mechanism when Parliament stood prorogued or dissolved. The distinction mattered procedurally: the composition of the triers and the role of the presiding officer differed between the two forums. Additionally, the Lord High Steward should not be confused with the Lord High Steward of Scotland, a separate hereditary office with no equivalent judicial function.

Why It Matters in Research
This court is almost entirely a historical artifact by the time American legal literature develops, and researchers encountering it will find it almost exclusively in English sources predating the twentieth century. The privilege of peerage trial — the doctrine that lords could not be tried by common juries — was abolished in England by the Criminal Justice Act 1948, which ended both the House of Lords peer trial jurisdiction and the Court of the Lord High Steward's function simultaneously. Any source citing this court postdating 1948 is either historical commentary or error.
The entry in Rapalje & Lawrence is spare to the point of being misleading. It defines the court solely by its subject-matter jurisdiction without noting the critical triggering condition: that the court convened only during parliamentary recess. Researchers relying on that entry alone will miss the relationship between this court and the Lords' own judicial function, which is the context that makes the court intelligible.
American legal dictionaries include this term primarily for completeness in describing English legal history. It has no American analog. The United States Constitution expressly rejected hereditary privilege, and no equivalent peer-trial mechanism was ever established in American courts. Researchers working in colonial or early federal materials who encounter references to peerage privilege are dealing with inherited English doctrine that had no operative force in American jurisdictions.
When tracing the history of criminal procedure for high-status defendants or the development of jury rights, this court sits alongside related institutions — the Court of Chivalry, the Court of the Earl Marshal — as evidence of the class-differentiated justice system that common law reformers were dismantling across the nineteenth century.

Historical Dictionary Support
Rapalje & Lawrence provide a single compressed sentence: the court is for "the trial of peers charged with treason or other felony, or misprision of treason or felony." The core jurisdictional statement is accurate but incomplete. The entry omits the parliamentary-recess trigger, the composition of the tribunal, and any indication that the office of Lord High Steward was itself a special commission rather than a continuously occupied position. Researchers consulting only this source will have the subject-matter scope but not the procedural context that distinguishes the court from the Lords' own jurisdiction. Older English legal dictionaries — Tomlin's Law Dictionary, Jacob's Law Dictionary, Bouvier in its more expansive editions — provide fuller treatment, including the distinction between the court's composition when only barons were summoned as triers versus when a fuller peerage was assembled.

Jurisdictional Note
The Court of the Lord High Steward is exclusively an English institution with no equivalent in Scotland, Ireland, or any American jurisdiction. Its abolition by the Criminal Justice Act 1948 renders it entirely historical for any research purpose beyond legal history and the development of criminal procedure doctrine.
