Why Are Double Jeopardy Protections Important?

In criminal law, “double jeopardy” refers to protections that ensure the government does not prosecute someone in criminal court more than once for the same offense. Double jeopardy protects defendants from the constant threat of prosecution after a court decides a case.

Defending yourself against criminal charges is draining and stressful. If you are facing multiple prosecutions, legal help is available to guide you through this complicated legal process. Talk to a criminal law attorney near you for help understanding your rights, preparing an effective defense, and ensuring you receive a fair trial. 

There are multiple reasons for the existence of double jeopardy in criminal law. As the U.S. Supreme Court noted, the “underlying idea” of double jeopardy is as follows:

“[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.”

Additionally, the double jeopardy clause gives due deference to a jury’s verdict. It also forces prosecutors to bring all relevant charges against a defendant. It, thus, requires them to review and prosecute a case competently.

This article describes the basis of double jeopardy protections and why these protections exist in criminal proceedings.

Double Jeopardy and the Fifth Amendment

Double jeopardy has a long history in criminal law. It is based on the Fifth Amendment to the U.S. Constitution.

The Fifth Amendment to the U.S. Constitution guarantees that no criminal defendant shall “be twice put in jeopardy of life or limb” for the same criminal offense. This means the government cannot prosecute a criminal defendant again after a case concludes. A case typically ends in acquittal or conviction. It also prevents the government from imposing multiple punishments for lesser-included offenses.

The Fifth Amendment prohibition against double jeopardy only applies to federal criminal cases. The Fourteenth Amendment’s due process clause applies this protection to state courts. Thus, you may assert a double jeopardy defense whether your criminal case is in state or federal court.

Double jeopardy applies to all criminal cases, including felonies and misdemeanors. The Fifth Amendment constitutional right against a second prosecution does not apply to civil cases.

But the double jeopardy rule is not absolute. For example, the court may allow a second state or federal prosecution if the first trial results in a mistrial. The court may allow a retrial on the same facts in such instances.

Under federal law, every criminal defendant can appeal the district court’s verdict. If the appellate court determines the trial court had insufficient evidence to convict the defendant, it may reverse the conviction.

If this occurs, the conviction is treated as an acquittal. In such a situation, double jeopardy applies. This means the government cannot prosecute the defendant a second time.

Reasons for Double Jeopardy Protection

It is important to understand the rationale for the double jeopardy rule. The following section describes why this protection exists in United States law.

Balancing Government Power

The double jeopardy clause of the Fifth Amendment is designed to protect citizens from their government. State and federal governments generally have more assets than the defendant. Double jeopardy keeps the government from using its superior resources to harass a citizen with multiple prosecutions. This is particularly true when a jury has found a defendant not guilty.

The government has the resources to prosecute a defendant again. The defendant likely does not have unlimited resources to defend themselves in court. Even if the prosecution does not intentionally intend to wear down the defendant, successive prosecutions would likely have that effect.

If not for double jeopardy protections, the government could use its first trial as another discovery period. This is a crucial stage in legal proceedings, allowing both sides to learn about each other’s evidence and arguments. Theoretically, this would allow the government to use the first trial as practice for its next prosecution.

The Toll of Successive Prosecutions

Double jeopardy recognizes the strain one criminal trial may cause and seeks to minimize such damages. It does so by preventing further prosecutions for the same offense.

Even if a jury acquits a defendant of any wrongdoing, both the monetary and emotional toll of the case can be significant. Facing criminal charges is stressful. Criminal defendants often face serious punishment and jail time for their alleged crimes. Defending against a criminal prosecution can be expensive, psychologically damaging, and stigmatizing.

Furthermore, without protections against double jeopardy, the government could essentially “wear down” a defendant until they plead guilty. Again, the government has nearly unlimited means to prosecute compared to a defendant. Double jeopardy is a criminal defendant’s shield against the government’s vast resources.

Validating a Judge’s Decision or Jury’s Verdict

Suppose a jury acquitted a criminal defendant. Suppose, further, that prosecutors could begin the same case again. This prosecution would undercut that jury’s verdict entirely. The same can be said for bench trials, where a judge determines guilt.

Another issue arises if the government could bring successive prosecutions after an acquittal. Without double jeopardy, the government could simply keep prosecuting the defendant. It could do so until it could find a jury willing to convict the defendant.

Prosecutors Must Carefully Consider Their Case

In criminal cases, prosecutors have only one opportunity to charge and prosecute a defendant for a particular offense. They decide which charges to bring against a defendant, and their charging decision can have a significant influence over a criminal case.

The charges influence any plea bargains and penalties. But limiting prosecutors to one shot at a prosecution encourages wise decision-making about the charging decisions in each case.
