Grady and the Same-Conduct Test

Grady and the Same-Conduct Test

Harris v. Oklahoma marks the outer edge of the elements approach to successive prosecutions, because it reads the greater offense through the theory of the first case and then runs the ordinary elements comparison on what that theory required.¹ For a few years the Court went past that edge. In Grady v. Corbin, decided in 1990, the defendant was involved in a traffic accident that killed an occupant of the other car, and he pleaded guilty to drunk driving and crossing the median line.² The State then charged criminally negligent homicide and reckless assault for the same accident and filed a bill of particulars naming the acts it would rely on: driving while intoxicated, failing to keep right of the median, and driving too fast for conditions.³ Two of those three acts were conduct for which the defendant had already been prosecuted, and that overlap decided the case.

The Court held the new charges barred. Its rule was that a later prosecution is prohibited if, to establish an essential element of the offense charged, the government will prove conduct that constitutes an offense for which the defendant has already been prosecuted.⁴ That result did not follow from the definitions of the crimes, since the homicide and assault charges were clearly permitted under the Blockburger elements comparison.⁵ The Court got past that obstacle by describing Blockburger as a technical comparison of the elements of two offenses, and by reading Harris as showing that the Court had never relied on that comparison alone to protect against multiple prosecutions.⁶ The resulting test moved the inquiry away from how the legislature defined the crimes and toward what the prosecutor planned to prove in the second trial, a plan that the bill of particulars made visible.

The same-conduct standard lasted three years. In United States v. Dixon, 509 U.S. 688 (1993), the Court returned to the Blockburger same-elements test, overruled Grady, and held that the protection against successive prosecution goes no further than the Harris application of Blockburger.⁷ Grady is therefore no longer good law, and a student who answers a same-offense question by asking whether the two prosecutions rest on the same conduct is applying a test the Court has discarded. The test that governs is the elements comparison: offenses are not the same if each requires proof of an element the other does not, even when the evidence needed to prove them overlaps substantially.⁸

The decision to abandon Grady was contested, and the reasons on each side show what is at stake. Four Justices wanted to keep the same-conduct test, arguing that an elements focus may be enough for cumulative punishment but leaves successive prosecutions unchecked, where a defendant could be forced to defend again and again and the government could perfect its case through dress rehearsal after dress rehearsal.⁹ The Justices who overruled Grady answered in three steps. The press of other demands on prosecutors and courts already discourages repeated prosecutions, so the danger was overstated.¹⁰ The same-conduct test could not cure that danger in any event, because only a broader same-transaction test could, and the Court had already rejected that approach. And the Clause uses a single phrase, "same offence," which cannot mean one thing when punishments are cumulated and another when prosecutions are successive.¹¹ That last answer carries forward the reasoning of Brown v. Ohio that offenses which are the same for barring consecutive sentences at one trial are the same for barring successive prosecutions.¹²

The reason the Court returned to elements is visible in what each test measures. The elements comparison asks what the legislature defined as a crime, so two provisions that each require a fact the other does not describe different wrongs, and a prosecution under each is not a second attempt at the same offense. A same-conduct test attaches the bar to whatever proof the State will offer in the later case, which lets a conviction on a minor charge foreclose a prosecution for a graver offense with distinct elements. That is what happened in Grady, where traffic offenses resolved by a guilty plea stood in the way of a homicide case.¹³ Returning to elements keeps the line Blockburger drew and leaves the State free to prosecute distinct wrongs. It still prevents the State from proving a second time the specific elements of a case it has already tried, which is the protection Harris supplies.

Two applications show where the line now falls. In Harris the felony-murder conviction required proof of a specific armed robbery, so a later prosecution for that robbery remains barred, because the robbery was part of the murder as the State prosecuted it.¹⁴ Now take the facts of Grady under the governing test. A conviction for drunk driving followed by a manslaughter charge for the resulting death does not trigger the bar, because drunk driving requires intoxication, which manslaughter does not, and manslaughter requires a death, which drunk driving does not.¹⁵ The conduct overlaps in both situations, so overlapping conduct cannot be what separates them. The difference is that every element of the robbery was contained in the first conviction in Harris, while neither traffic offense contains the other in the Grady facts.

The same result follows when two charges rest on the same documents. In a time-card prosecution, the defendants argued that stealing from a federal agency under § 641 and making materially false statements under § 1001(a) were the same offense because both counts were accomplished by submitting false time cards, relying on Grady.¹⁶ The court rejected the argument because Dixon overruled Grady, and the elements differed: § 1001(a) requires a materially false statement, which § 641 does not, while § 641 as charged requires theft of more than $100, which § 1001(a) does not.¹⁷ The shared time cards changed nothing.

The pair shows what Dixon did and did not change. It left intact the bar that applies when one offense is contained in the other, in either order, and removed only the additional layer that Grady had placed on top of the elements comparison.

Step one does the real work in felony-murder and similar alternative-element settings, because the statute's text alone would make the predicate felony look like an extra fact. Students lose this issue when they treat shared conduct as enough to bar the later case, since after Dixon the same crash, the same documents, or the same witnesses can support two prosecutions whenever each offense requires a fact the other does not.¹⁸
