Definition
The Lord Chief Baron was the presiding judge of the English Court of Exchequer, holding the senior position among the judges — styled "barons" — of that court. The office carried both judicial and administrative authority over the Exchequer's common law jurisdiction, which developed over centuries from the court's original fiscal and revenue functions into a court of general common law competence.
The office ceased to exist as a functioning judicial post following the Judicature Acts of 1873–1875, which abolished the Court of Exchequer as a separate institution and merged it, along with the Courts of Common Pleas and Queen's Bench, into the newly constituted Supreme Court of Judicature. After that consolidation, the title became obsolete. The last Lord Chief Baron was Sir FitzRoy Kelly, who held the office until its abolition.

Common Confusion
LORD CHIEF BARON vs. LORD CHIEF JUSTICE: These are distinct offices. The Lord Chief Justice was the presiding judge of the Court of Queen's (or King's) Bench, not the Exchequer, and that office survived the Judicature Acts — continuing today as the head of the judiciary in England and Wales. Researchers encountering both titles in pre-1875 sources should not conflate them. The Lord Chief Baron's title disappeared entirely; the Lord Chief Justice's title did not.
LORD CHIEF BARON vs. BARON OF THE EXCHEQUER: The subordinate judges of the Exchequer were styled simply "barons" — not Lords. The Lord Chief Baron was the chief among them. Rapalje & Lawrence cross-references BARON to clarify this relationship.

Why It Matters in Research
This is a historical term, obsolete since 1875. Researchers encountering it in primary sources, law reports, or treatises should understand several navigational points.
First, pre-Judicature Acts English law reports are organized by court. Exchequer cases — including those decided or presided over by the Lord Chief Baron — appear in the Exchequer Reports (Exch.) and related reporters such as Welsby, Hurlstone & Gordon, and others. These are distinct from King's Bench or Common Pleas reporters.
Second, the Exchequer's jurisdiction evolved substantially. Its earliest function was revenue and fiscal matters for the Crown; its common law jurisdiction expanded through the legal fiction of "quominus," which allowed ordinary litigants to invoke the court's jurisdiction by alleging they were debtors of the Crown. Researchers reading opinions of the Lord Chief Baron from different centuries should be alert to this jurisdictional evolution — an opinion from the seventeenth century and one from the nineteenth may arise from very different procedural contexts.
Third, after 1875, cases from the former Court of Exchequer were absorbed into the Exchequer Division of the High Court of Justice, which was itself merged into the Queen's Bench Division in 1881. Chain-of-authority questions — whether a Lord Chief Baron's ruling carries precedential weight in a post-1875 court — require attention to this transition.
Fourth, American researchers should note that no equivalent office exists or ever existed in U.S. federal or state court systems. References to the Lord Chief Baron in American legal writing are invariably citations to English authority.

Historical Dictionary Support
All three source dictionaries agree on the essential definition: the Lord Chief Baron was the chief judge of the Court of Exchequer, and the office became obsolete following the Judicature Acts. The entries are brief and consistent on this point.
Bouvier's is the most explicit in flagging obsolescence, noting the title is "now obsolete" — which is the most practically useful signal for a researcher. Black's and Rapalje & Lawrence provide the same substantive content without that explicit flag.
None of the three entries address the internal structure of the Exchequer bench, the historical development of the court's jurisdiction, or the mechanics of the Judicature Act consolidation. For those questions, researchers should consult Blackstone's Commentaries (Book III), Holdsworth's History of English Law, or the prefatory materials in the English Reports series covering Exchequer cases.
Rapalje & Lawrence's cross-reference to BARON,2 is useful: the general entry for "baron" in that dictionary addresses the Exchequer bench judges collectively and provides context that the LORD CHIEF BARON entry assumes.

Jurisdictional Note
The office existed only in England. Scotland, Ireland, and the British colonies each had distinct court structures. The term has no equivalent in American law. Researchers working in Irish legal history should note that Ireland had its own Court of Exchequer with its own Chief Baron, a separate office from the English Lord Chief Baron.
