Case Brief Summary & Legal Analysis
tl;dr: The Supreme Court reversed a conviction for transporting a stolen airplane across state lines, finding that an airplane is not a “motor vehicle” under the National Motor Vehicle Theft Act because the term’s common meaning refers to land-based vehicles.
Legal Significance: A landmark case establishing the rule of lenity. Criminal statutes must provide fair warning in language commonly understood, and ambiguous terms will be construed narrowly, not extended to cover conduct beyond the statute’s clear scope.

Case Facts & Court Holding
Key Facts & Case Background
The petitioner, William McBoyle, was convicted under the National Motor Vehicle Theft Act of 1919 for knowingly transporting a stolen airplane from Ottawa, Illinois, to Guymon, Oklahoma. The Act criminalized the interstate transportation of a stolen “motor vehicle.” The statute defined “motor vehicle” to include “an automobile, automobile truck, automobile wagon, motor cycle, or any other self-propelled vehicle not designed for running on rails.” McBoyle appealed his conviction, arguing that an airplane did not fall within the statutory definition of a “motor vehicle.” The Circuit Court of Appeals affirmed the conviction, holding that the phrase “any other self-propelled vehicle” was broad enough to include an aircraft. The Supreme Court granted certiorari to resolve the question of whether the Act applied to airplanes.
