In Brown v. Ohio, 432 U.S. 161, the Supreme Court held that the Double Jeopardy Clause of the Fifth Amendment bars a state from prosecuting a defendant for a greater offense after it has already convicted him of a lesser included offense arising from the same conduct.1Legal Information Institute. Brown v. Ohio, 432 U.S. 161 The protection reaches state prosecutions through the Fourteenth Amendment.2Legal Information Institute. Benton v. Maryland, 395 U.S. 784
The Facts Behind the Case
Nathaniel Brown took a car from a parking lot in East Cleveland on November 29, 1973. Nine days later, Wickliffe police caught him driving it. Ohio charged him with joyriding under Ohio Revised Code ยง 4549.04(D), which defined the offense as taking or operating a vehicle without the owner’s consent. Brown pleaded guilty, served 30 days, and paid a $100 fine.1Legal Information Institute. Brown v. Ohio, 432 U.S. 161
After he finished that sentence, a Cuyahoga County grand jury indicted him for auto theft of the same vehicle. Brown objected on double jeopardy grounds. The case reached the Supreme Court.1Legal Information Institute. Brown v. Ohio, 432 U.S. 161
Why Joyriding and Auto Theft Counted as the Same Offense
To decide whether two charges are the “same offense,” courts apply the Blockburger test: each statute must require proof of a fact that the other does not.3Legal Information Institute. Blockburger v. United States, 284 U.S. 299 Joyriding required taking or operating a car without consent. Auto theft required those same elements plus the specific intent to keep the car permanently. Joyriding demanded no fact that auto theft did not also demand, so it was a lesser included offense of auto theft. For double jeopardy purposes, the two statutes were not distinct crimes.4Justia. Brown v. Ohio, 432 U.S. 161
The Holding on Successive Prosecutions
Because Ohio had already convicted Brown of the lesser included offense, it could not come back and try him for the greater one. The Court made clear that the order of charges does not matter. A conviction on the lesser charge blocks a later trial on the greater, and a conviction on the greater charge blocks a later trial on the lesser. The clause stops the government from putting a defendant through repeated trials for what is legally one crime, and it protects the finality of the first judgment.5Congress.gov. Amdt5.2.7.2 Successive Prosecutions
When a Second Prosecution Is Still Allowed
The bar is not absolute. Two narrow exceptions let the state bring a later, more serious charge.
The first applies when the facts needed for the greater offense had not yet occurred at the time of the first prosecution. The classic example is an assault conviction followed by the victim’s death from the same injuries; the state may then charge homicide, because the greater crime was not legally complete when the first case was tried.6Justia. Diaz v. United States, 223 U.S. 442
The second applies when the facts supporting the greater offense had not been discovered despite the exercise of due diligence. This is not a safety net for weak preparation; it covers evidence that was not reasonably available when the first trial took place.5Congress.gov. Amdt5.2.7.2 Successive Prosecutions
