Crime as Offense Against a Sovereign

Crime as Offense Against a Sovereign

The Double Jeopardy Clause protects a person from being twice put in jeopardy "for the same offence," so the unit it protects is the offence, a legal category distinct from the physical act or the stretch of conduct the defendant engaged in.¹ The Court has long defined that word by reference to law: "[a]n offence, in its legal signification, means the transgression of a law."² A transgression requires something transgressed, and every criminal law belongs to a particular government that enacted it and enforces it. The common law reflected this by treating a crime as an offense against the sovereignty of the government, an injury to that government's "peace and dignity."³ Once an offence is understood as the breach of a particular sovereign's law, the identity of that sovereign becomes part of what the offence is.

The rest of the reasoning follows one link at a time. A single act can break the laws of two sovereigns, as when conduct violates both a federal statute and a state statute, or the statutes of two different states. Each sovereign's law defines its own offence, so the defendant who has broken both has, as the Court explained in Moore v. Illinois, "committed two offences, for each of which he is justly punishable."⁴ It follows that a prosecution by each sovereign answers a different transgression, and the defendant has not been punished twice for the same offence. The English common law reached the same result, treating violations of different governments' laws as separate offences even when the two laws define the crime identically.⁵ Identical wording does not matter because the states exercise governmental power in their own right instead of serving as administrative divisions of one national sovereign, so a state statute and a federal statute serve different interests even when they reach the very same conduct.⁶

The doctrine is an interpretation of the word "offence" in the clause itself. It is not an exception that suspends the clause whenever two governments are involved. The clause continues to apply in full, and it simply has nothing to say about the second prosecution, because that prosecution is not for the same offence as the first.⁷ That framing explains why the doctrine is categorical: two crimes prosecuted by different sovereigns are never the same offence, even when their statutory elements are identical, so the only question is whether the prosecuting authorities are different sovereigns.⁸ The alternative shows the practical reason. If the sovereign were not part of the offence, one government's charging choice, such as a lenient charge or a plea to a minor crime, would shut off another government's ability to punish a serious violation of its own law. The protection against repeated prosecution by the same government stays intact, which fits the Court's own phrasing of the single-government concern: "Our minds rebel against permitting the same sovereignty to punish an accused twice for the same offense."⁹

Inside a single sovereign the same-offence question is far more generous to the defendant. Separate statutory crimes need not be identical in elements or in proof to count as the same offence, and a greater offence and its lesser included offence are treated as one.¹⁰ In Brown v. Ohio the defendant pleaded guilty to joyriding, meaning operating a car without the owner's consent, and was later indicted for stealing the same car. Joyriding was a lesser included offence of auto theft under Ohio law, so the Court reversed the second conviction.¹¹ Both prosecutions in that case rested on one State's law, which is why the overlap between the charges decided the matter.

The contrast with Brown is what makes Heath v. Alabama instructive. Georgia had convicted Heath of malice murder for the killing of his wife, and Alabama then prosecuted him for the capital offence of murder during a kidnaping. Heath argued that the two offences were greater and lesser versions of each other, and Alabama did not dispute the point, so the Court assumed for the sake of argument that a second conviction would have been barred had both offences arisen under one State's law.¹² The Court still allowed the Alabama prosecution, because the offences were defined by the laws of two different States, which are separate sovereigns.¹³ Heath therefore never decided that the offences were different. It assumed they were the same and let the second prosecution proceed because the sovereign had changed.

The two scenarios differ in a single variable, and that variable is the whose-law question. The doctrine looks at which sovereign's law was violated and never at how much the two charges overlap. Overlap between charges decides the same-offence question within one sovereign, as in Brown, but it cannot decide the question across sovereigns, because a second government's law defines a second offence however closely it tracks the first. A common error on exams is to stop the analysis at greater-and-lesser overlap and declare the second prosecution barred, when the first thing to check is whether a different sovereign brought it.
