Definition
The Palmer Act is the popular name for the English statute 19 & 20 Vict. c. 16 (1856), which extended the jurisdiction of the Central Criminal Court (the Old Bailey) to permit trials of persons accused of crimes committed outside that court's ordinary territorial jurisdiction. Before the Act, jurisdiction in criminal matters was generally fixed to the locality where the offense occurred. The Palmer Act created a statutory exception allowing the Crown to bring a prosecution in the Central Criminal Court even when the underlying crime was committed elsewhere in England.
The Act takes its name from the circumstances that prompted it: the prosecution of William Palmer, a physician from Rugeley, Staffordshire, who was accused of poisoning a companion. Local prejudice in Staffordshire was considered so intense that a fair trial there was thought impossible, yet the Central Criminal Court in London lacked ordinary jurisdiction. Parliament responded by passing the statute specifically to permit Palmer's trial to proceed at the Old Bailey. Palmer was tried, convicted, and hanged in 1856.

Common Confusion
The Palmer Act is occasionally confused with general change-of-venue procedures, but the two are distinct. A change of venue transfers a case from one court of competent jurisdiction to another. The Palmer Act did something more fundamental: it conferred jurisdiction on a court that would otherwise have had none, regardless of whether that court's existing jurisdiction had been properly invoked. The Act also should not be confused with any American legislation of the same name; it is exclusively an English statutory instrument with no direct American counterpart.

Why It Matters in Research
This term appears almost exclusively in nineteenth-century English criminal law sources. Researchers are unlikely to encounter it in American legal materials except as a historical or comparative reference. Several cautions apply:
First, the term is heavily tied to a single case. Sources discussing the Palmer Act are almost always discussing either the legislative history prompted by the Palmer poisoning trial or the broader principle that Parliament can legislate ad hoc to cure jurisdictional gaps in criminal proceedings. A researcher finding the term in a treatise should determine whether the author is using it to discuss the jurisdictional principle generally or the Palmer case specifically.
Second, the statute itself represents an early instance of what would now be called special jurisdiction legislation — Parliament's willingness to expand a court's territorial reach by statute rather than waiting for systemic procedural reform. This connects to the broader nineteenth-century movement toward consolidation of criminal courts and standardization of criminal procedure, culminating in later reforms such as the Judicature Acts of the 1870s.
Third, researchers working in comparative criminal procedure or legal history may encounter the Palmer Act cited as a precursor to modern change-of-venue and transfer-of-jurisdiction provisions, both in England and in jurisdictions that inherited English common law frameworks. That genealogy is suggestive but should be traced carefully; the Palmer Act conferred jurisdiction rather than merely moving a case.
Fourth, the Act's popular name is stable across sources — both editions of Black's are consistent — but researchers should confirm they are locating the correct statute (19 & 20 Vict. c. 16) when working in primary sources, as Victorian-era statute naming conventions were informal and popular names did not always persist into official indexes.

Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary offer identical, brief definitions. Both correctly identify the statute by its regnal citation (19 & 20 Vict. c. 16) and its core function: enabling trial in the Central Criminal Court of persons accused of crimes committed outside that court's ordinary jurisdiction. Neither edition elaborates on the legislative history, the Palmer trial, or the broader doctrinal significance of the Act. The entries read as simple identification tags rather than substantive analyses, which is consistent with how Black's treated well-settled, narrowly applicable English statutory terms in this period.
No meaningful divergence exists between the two editions beyond minor typographical variation. Researchers should note that neither edition contextualizes the Act within the trajectory of English criminal procedure reform, an omission that can leave users underestimating how unusual the legislation was at the time of its passage.

Jurisdictional Note
The Palmer Act is English legislation with no direct application in American jurisdictions. It may appear in nineteenth and early twentieth-century American legal treatises as a comparative example of legislative jurisdiction-conferring authority, but it has no operative force outside England.
