Definition
A Scots law term for murder committed pursuant to a previously formed design or plan to kill. The concept is the Scottish legal equivalent of what English and American law would call premeditated murder: a homicide preceded by deliberate forethought rather than arising from sudden passion or accident. The term does not describe a category of felony in the common law tradition; it is a term of art specific to Scots criminal law, drawing on the civilian-influenced jurisprudence of the Scottish legal system.
The operative element is the "previous design" — a settled intention to kill formed before the act of killing, distinguishing forethought felony from culpable homicide committed in the heat of the moment.

Common Confusion
FORETHOUGHT FELONY should not be confused with the English or American doctrine of premeditated murder, though the concepts are closely related in function. The term is Scots law vocabulary; using it in the context of English common law or American statutory murder analysis is historically anachronistic and terminologically imprecise. Researchers working in cross-jurisdictional historical sources should be alert to the difference.
The term also bears no relationship to the American "felony murder rule," which imposes murder liability for deaths occurring during the commission of certain felonies regardless of intent. Forethought felony is defined entirely by prior intent; felony murder can attach without any intent to kill at all.

Why It Matters in Research
This term appears almost exclusively in pre-20th century legal dictionaries and Scots law treatises. Its presence in the Law Mind corpus is a marker of historical source material, not contemporary doctrine. Researchers encountering the term in primary sources should treat it as a signal that the document is either (1) Scots law in origin, (2) a general legal dictionary compiled from civilian and mixed-jurisdiction sources, or (3) a comparative criminal law discussion.
The primary authority cited across all four source dictionaries is Erskine's Institutes (Book IV, Title 4, Section 50), which remains the standard Scots institutional writer on the subject. Bell's Dictionary of the Law of Scotland is the secondary citation. Researchers seeking to trace the doctrinal substance — not just the term — should consult those sources directly rather than relying on the dictionary entries alone, which are uniformly brief.
For researchers working on the history of murder law, forethought felony sits at the intersection of premeditation doctrine and the Scottish institutional tradition. The concept helped shape how Scots law distinguished murder from culpable homicide (the Scottish equivalent of manslaughter), a distinction that operated differently from the English common law framework. Cross-referencing with sources on malice aforethought will help researchers understand the parallel English development and where the two systems converged or diverged.
American researchers should note this term will not appear in domestic case law or statutes. Its appearance in American legal dictionaries of the 19th century reflects the encyclopedic, multi-jurisdictional ambitions of that period's legal lexicographers rather than any operative American doctrine.

Historical Dictionary Support
All four source dictionaries — Black's (1st and 2nd editions), Burrill's, and Bouvier's — give materially identical definitions: murder committed in consequence of a previous design. The uniformity is notable and suggests all are drawing from the same limited primary source pool (Erskine and Bell) rather than independently analyzing the doctrine.
None of the entries elaborate on what "previous design" requires — whether a fleeting prior intent suffices or whether some duration of premeditation is necessary, a question Scots law itself debated. None address how forethought felony was proved at trial, or how it interacted with defenses available under Scots law. The dictionary record is a starting point only; it accurately identifies the term but does not map its doctrinal edges.
Burrill's entry is the most compact, essentially reproducing the Bell's Dictionary formulation verbatim. Bouvier's is the only entry to cite both Erskine and Bell explicitly and with sufficient precision to locate the passage in the Institutes, making it marginally more useful for source-tracing.

Jurisdictional Note
This is a Scots law term with no operative counterpart in English common law jurisdictions or American law. It should not be imported into legal analysis outside the Scottish legal context. Researchers working with Scottish criminal law materials will find the term current in historical sources through at least the 19th century.

The Law Mind Criminal Law Encyclopedia — Homicide: Felony Murder Rule (criminal_27)
Note: The felony murder rule is a distinct doctrine, but the encyclopedia entry provides essential context for understanding how Anglo-American law constructed intent-based gradations of homicide — the broader framework within which forethought felony's Scottish analog can be situated comparatively.
