The protection against double jeopardy prevents defendants from being criminally prosecuted more than once for the same offense. Many people have heard this phrase on TV or in movies, but in criminal cases, double jeopardy is an essential constitutional right that ensures the government cannot repeatedly file charges for the same act.

In this article, you’ll learn about the double jeopardy principle and its application in criminal law. For specific legal advice, contact a criminal defense attorney.

Double Jeopardy Defined

The Fifth Amendment to the United States Constitution contains the double jeopardy clause. It states that no person shall “be subject for the same offense to be twice put in jeopardy of life or limb.” For criminal defendants, this is a crucial constitutional right.

Technically, the Fifth Amendment protection against double jeopardy only applies to federal criminal cases. However, the Fourteenth Amendment’s due process clause extends this protection to state courts. Most state constitutions similarly protect individuals from retrial for the same crime. Thus, you may assert a double jeopardy defense whether your criminal case is in state or federal court. It generally applies regardless of the severity of the alleged offense.

Historical Background of Double Jeopardy

The concept of double jeopardy is one of the oldest protections in Western legal systems. Its exact origins are unclear. However, the principles existed long before the United States Constitution was drafted.

English Common Law

In English common law, the protection against double jeopardy was a widely accepted rule that applied across different cultures and legal systems. But the English double jeopardy doctrine was narrow. It only afforded protection to defendants accused of capital felonies. It also only applied after a conviction or acquittal. It did not apply to cases dismissed before final judgment. Moreover, it was not immune to abuse by the British Crown.

Double Jeopardy in the United States

The American colonists were intimately familiar with the writings of the English jurists. Copies of Sir William Blackstone’s Commentaries on English law were available in most colonies. Colonists cited his teachings to support their claims against the English Parliament.

The colonists also knew how narrowly England defined the right against double jeopardy. The Framers of the Constitution debated double jeopardy during the Constitutional Convention after the Revolutionary War. There, James Madison sought to expand the scope of double jeopardy.

Madison sought to make the right against double jeopardy applicable to all crimes, not just capital felonies. The initial draft provided that “No person shall be subject … to more than one punishment or one trial for the same offense.” But several convention members objected to this wording. They argued that it could prevent defendants from seeking a second trial on appeal. Ultimately, the Framers modified the language of the Fifth Amendment to address this concern. However, the final version ratified by the states left other questions for judicial interpretation.

What Does Double Jeopardy Protect Against?

Today, the prohibition against double jeopardy protects a criminal defendant from the following:

• Prosecution for the same criminal offense after an acquittal
• A second prosecution for the same criminal offense after a conviction
• Prosecution after certain mistrials
• Facing more than one punishment for a single offense

Note that double jeopardy protections generally do not extend to civil penalties such as forfeiture. In United States v. Ursery (1996), the Supreme Court ruled that civil asset forfeiture is a remedial civil sanction. It is not a criminal punishment, and therefore it does not trigger the double jeopardy clause under the Fifth Amendment. This means the government can still seek to seize assets connected to the criminal activity. This applies even when the defendant cannot be retried for the underlying offense.

Why Is Double Jeopardy Important?

There are several reasons behind the rule against double jeopardy. As the U.S. Supreme Court noted in Green v. United States (1957), the underlying idea of double jeopardy is:

“[T]hat the State with all its resources and power should not be allowed to make repeated attempts to convict an individual for an alleged offense, thereby subjecting him to embarrassment, expense, and ordeal and compelling him to live in a continuing state of anxiety and insecurity, as well as enhancing the possibility that even though innocent, he may be found guilty.”

The principle serves several important functions for the legal system:

• Preserves the finality of criminal proceedings: Validates jury verdicts and judicial decisions. Without double jeopardy protections, the government could keep prosecuting a defendant until it found a jury willing to convict. This would fundamentally undermine the integrity of the judicial process.
• Imposes limits on prosecutors: Prosecutors have only one opportunity to charge and prosecute a defendant for a particular offense. This encourages careful decision-making about charging decisions, as these choices influence plea bargains and penalties.
• Protects individuals from the financial and emotional toll of repeated prosecutions: Even if a jury acquits a defendant, the costs can be high. Defending against prosecution can be expensive, psychologically damaging, and stigmatizing.
• Balances government power against individual rights: State and federal governments generally have more assets than defendants. Double jeopardy prevents the government from using its superior resources to harass citizens with multiple prosecutions. It also prevents the government from using the first trial as practice for subsequent attempts.

States can provide greater protection against multiple punishments than the U.S. Constitution does — but not less. Understanding the nuance of state and federal double jeopardy laws can be confusing. A criminal law attorney in your area can help clarify your rights and options.

Examples of Double Jeopardy

These protections apply in practice in various scenarios. Here are some common examples:

Suppose law enforcement arrested John for driving while intoxicated (DWI). His criminal case proceeds to a jury trial in a state district court. The jury ultimately acquits John of his criminal charges. An acquittal means the suspect is found not guilty of the charged offenses. Under the Double Jeopardy Clause, the prosecution cannot come back for the second time and try John for the same DWI.

Now, suppose a police officer spots John weaving all over the road one week after his first trial ended. The officer pulls him over and arrests him for DWI. The Double Jeopardy Clause does not protect him from facing these charges. The new arrest now involves a separate incident that happened on a different date. Each offense is a separate criminal act. As a result, the prior acquittal protects him only from prosecution for the first offense, not for future charges.

What Is Considered the Same Offense?

The double jeopardy rule applies to the re-prosecution of the same person for the same offense. But what constitutes the same offense? It may sound straightforward, but it is not always as clear as it seems. State and federal courts use various tests to determine whether the same facts have already been litigated.

The Blockburger Test

Under common law, a single episode of criminal behavior gave rise to only one prosecution, regardless of how many wrongful acts the suspect committed during that episode. Over time, the government began prosecuting defendants for several crimes from the same event.

The Supreme Court addressed this issue in Blockburger v. United States (1932), resulting in what became known as the Blockburger test, also referred to as the “same elements” test.

The Blockburger test requires courts to consider multiple factors:

• The court must examine the statutory elements of each offense without regard to the actual evidence that the prosecution will introduce at trial.
• The prosecution must demonstrate that each offense has at least one different element.
• If one offense entirely subsumes another, the two offenses are deemed the same for purposes of a double jeopardy analysis.

Double jeopardy does not protect the defendant if each offense requires the government to prove an additional fact not found in the other offense.

For example, suppose the government charges a person with arson and robbery. The government must prove different necessary facts for each charge. Thus, the defendant cannot claim double jeopardy.

Alternatively, suppose the government charges a person with burglary and trespassing. To prove beyond a reasonable doubt that the defendant committed burglary, the prosecution must prove that the defendant trespassed. This is known as a lesser-included offense. Because trespass is generally a lesser-included offense of burglary, it is usually treated as the “same offense” for double jeopardy purposes, and a defendant typically cannot receive separate punishments for both offenses unless the legislature clearly authorizes cumulative punishment.

The Supreme Court ruled in Brown v. Ohio (1977) that the double jeopardy doctrine applies to greater- and lesser-included offenses. For example, if a court convicts a defendant of domestic violence, the same court cannot later try to convict them for the more severe charge of aggravated assault for that same incident. Also, if a jury acquits a defendant of an aggravated assault charge, the court cannot later try them again for a simple assault that is based on the same facts.

Other Tests Courts Use Beyond Blockburger

While the Blockburger test is the most common approach, courts sometimes apply additional principles to determine if two prosecutions violate double jeopardy protections:

• Collateral estoppel: Once a jury decides a key factual issue in your favor, prosecutors cannot retry that same issue in a different case. For example, in Ashe v. Swenson (1970), a defendant was acquitted of robbing one poker player because the jury found the identification evidence too weak. The government then tried to prosecute him for robbing a different player from the same poker game. The Supreme Court blocked this second prosecution—the identification question had already been decided.
• “Same transaction” analysis: This approach would require prosecutors to charge all related offenses from one criminal episode together in a single case. Though proposed by Justice Brennan in Brown v. Ohio (1977), no federal court currently uses this standard.
• “Same conduct” test: Previously prohibited prosecuting someone twice for the same conduct, regardless of how the charges were labeled. The Supreme Court applied this in Grady v. Corbin (1990) but later overruled it in United States v. Dixon (1993). Today, courts rely primarily on the Blockburger elements test instead.

A criminal law attorney in your area can help you better understand these tests and how they may apply to your situation or criminal case.

What If New Evidence Comes To Light?

New evidence generally cannot lead to a subsequent prosecution for the same crime after an acquittal, or after jeopardy has attached and the case ends in a way that bars retrial. Prosecutors get one shot to build and argue the best case they can. Allowing further evidence to lead to additional trials could create a never-ending legal process for a single defendant. But a case can be refiled if jeopardy never attached or if a mistrial or similar event permits a retrial.

The same defendant might face criminal charges for a different criminal offense tangentially related to the initial offense. For example, suppose the state charged someone with assault and lost at trial. The state could still separately prosecute charges for drug crimes that occurred around the same time. The double jeopardy rule would not apply.

How Does Double Jeopardy Affect the States?

The protection generally applies even in jurisdictions that do not expressly prohibit double jeopardy. In Benton v. Maryland (1969), the U.S. Supreme Court held that double jeopardy applies to state and federal prosecutions under the Fourteenth Amendment doctrine of incorporation of rights.

Perhaps the most significant exception to the double jeopardy prohibition is the dual sovereignty doctrine. The Supreme Court ruled in 2019 that federal and state governments are separate sovereigns. They have separate authority to prosecute crimes. Because of this, a person convicted or acquitted of a crime in state court can be subsequently prosecuted and convicted federally for the same offense.

Likewise, if a criminal act or episode crosses state lines, both states can prosecute the crime independently without violating the constitutional protections of the double jeopardy clause.
