Yes, a single act can be both a tort and a crime, and when it is, two entirely separate cases can proceed against the same person at the same time. One is a civil lawsuit brought by the injured person to recover money. The other is a criminal prosecution brought by the government to punish conduct the law forbids. They run on parallel tracks, follow different rules, and can end in opposite results without contradicting each other.
One Act, Two Cases
A tort is a civil wrong: conduct that causes harm to another person. Tort law exists to make the injured person financially whole, and the remedy is almost always money for things like medical bills, lost income, and pain. A crime is conduct that violates a law the government enacted to protect society. Criminal law exists to punish and deter, and its consequences range from fines paid to the state to imprisonment.
The two systems overlap whenever the same conduct both breaks a criminal statute and injures someone privately. A drunk driving crash is the cleanest example. Driving intoxicated violates traffic laws, so the state can file criminal charges seeking fines, license suspension, or jail time. The crash also injured someone, so that person has a separate right to sue the driver for negligence in civil court. Neither case depends on the other. The prosecutor does not need the victim’s permission to file charges, and the victim does not need a criminal conviction to bring a lawsuit.
Who Runs Each Case
In the civil case, the injured person is the plaintiff and runs the show. They decide whether to sue, what to claim, whether to settle, and when to drop it. The person accused of causing the harm is the defendant.
In the criminal case, the government is the plaintiff. A prosecutor files charges on behalf of the state or the federal government and alone decides whether to pursue them or drop them. The victim is not technically a party. Prosecutors can proceed even when the victim does not want them to, and they can accept plea deals the victim disagrees with. Federal law gives crime victims certain procedural rights, including the right to be heard at hearings involving release, plea agreements, or sentencing, and to receive restitution as provided by law.1GovInfo. 18 USC 3771 – Crime Victims Rights Those rights give a voice, not control.
The Proof Standards Are Different
The most consequential difference between the two cases is how much evidence it takes to win.
In a civil tort case, the plaintiff needs to prove the claim by a preponderance of the evidence. That means showing it is more likely true than not, anything over the 50-percent line.2United States District Court District of Vermont. Burden of Proof – Preponderance of Evidence If the evidence tips even slightly in the plaintiff’s favor, the plaintiff wins.
Criminal cases demand far more. The prosecutor must prove guilt beyond a reasonable doubt, which requires evidence that leaves jurors firmly convinced of guilt with no reasonable alternative explanation. It is the highest standard in the legal system, and it exists because a criminal conviction can take a person’s freedom.3Constitution Annotated. Amdt5.3.1 Overview of Double Jeopardy Clause
That gap is not a technicality. It is why the same evidence can produce a not-guilty verdict in criminal court and a finding of liability in civil court on the same set of facts. The evidence did not change; the measuring stick did.
Why an Acquittal Does Not End the Civil Case
A not-guilty verdict does not shut the door on a civil lawsuit. The Fifth Amendment’s Double Jeopardy Clause prevents the government from prosecuting someone twice for the same crime, but it generally does not apply to noncriminal proceedings.3Constitution Annotated. Amdt5.3.1 Overview of Double Jeopardy Clause A civil tort case is not a second prosecution. It is a different kind of case, brought by a different party, aiming at a different remedy, and measured by a lower standard.
The best-known illustration is the O.J. Simpson case. In 1995, a criminal jury acquitted Simpson of murder. Two years later, a civil jury found him liable for the wrongful deaths of Nicole Brown Simpson and Ronald Goldman, awarding the Goldman family $8.5 million in compensatory damages and $12.5 million in punitive damages, with an additional $12.5 million in punitive damages to the estate of Nicole Brown Simpson. The criminal jury was not convinced beyond a reasonable doubt. The civil jury found it more likely than not that Simpson caused the deaths. Both verdicts were legally correct under their own standards.
How a Conviction or Plea Affects the Civil Case
The relationship runs strongly in the other direction. A criminal conviction usually helps the civil plaintiff. Through a doctrine called collateral estoppel, facts proven and decided in the criminal case generally cannot be relitigated later in a civil case involving the same defendant. If a criminal jury already found beyond a reasonable doubt that the defendant committed a specific act, the civil plaintiff can point to that finding rather than proving the same fact from scratch. Evidence that met the higher criminal standard necessarily meets the lower civil one.
Plea deals split into two categories. A straight guilty plea is generally treated as an admission and can be used against the defendant in a later civil case. A no-contest plea (nolo contendere) is different. Federal Rule of Evidence 410 bars a nolo contendere plea from being admitted as evidence against the defendant in either a civil or criminal case.4Legal Information Institute. Federal Rules of Evidence Rule 410 – Pleas, Plea Discussions, and Related Statements That is why defense attorneys sometimes negotiate a no-contest plea when a civil lawsuit is likely. The defendant resolves the criminal case without handing the plaintiff a ready-made admission. Some states carve out exceptions for felonies, but the federal rule is a bright line.
What Each Side Can Win or Lose
A successful tort claim produces a monetary judgment. Damages typically split between compensatory damages that reimburse actual losses (medical expenses, lost income, property damage) and general damages for harder-to-quantify harm like pain and physical impairment. When the defendant’s conduct was especially reckless or malicious, courts can also award punitive damages designed to punish and deter. In practice, the money comes from the defendant or the defendant’s insurer.
A criminal conviction produces a sentence: fines paid to the government, probation, community service, mandatory treatment, or imprisonment, depending on the offense, the defendant’s history, and sentencing rules. None of that goes directly to the victim. Courts can order restitution as part of a criminal sentence, but restitution usually covers only the victim’s direct, out-of-pocket losses. It does not cover pain and suffering or other non-economic harm the way civil damages can. Even when restitution is ordered, a civil lawsuit may still be worth pursuing for the full scope of the losses.
The Right to a Lawyer Only Applies on One Track
The Sixth Amendment guarantees anyone facing criminal prosecution the right to a lawyer, and if they cannot afford one, the court must appoint one.5Constitution Annotated. Amdt6.6.3.1 Overview of When the Right to Counsel Applies That right begins once the government formally initiates charges.
Civil court has no equivalent. If you are sued for a tort and cannot afford an attorney, you represent yourself. Plaintiffs also pay for their own lawyers, though contingency fee arrangements (typically one-third to 40 percent of any recovery) let many injured people bring cases they could not otherwise afford. Civil defendants have no parallel option; they hire a lawyer, rely on insurance that includes a defense, or handle it alone.
The Fifth Amendment Problem When Both Cases Are Live
When the criminal and civil cases are running at the same time, the defendant faces a hard choice. The Fifth Amendment’s protection against self-incrimination is not limited to criminal court. A party or witness in a civil case can invoke it whenever an answer might be used against them in a current or future criminal proceeding.6Constitution Annotated. General Protections Against Self-Incrimination Doctrine and Practice The Supreme Court confirmed this in McCarthy v. Arndstein in 1924.
Here is where it turns uncomfortable. In the civil case, the plaintiff’s attorney can depose the defendant, demand documents, and ask pointed questions about the incident. Honest answers can become evidence in the criminal prosecution. Silence has its own cost: in civil court, the judge or jury is allowed to draw a negative inference from a defendant’s refusal to answer. In criminal court, they are not. Defendants often ask the civil court to pause the lawsuit until the criminal case ends. Courts have discretion to grant these stays but are not required to. They weigh how much the defendant’s Fifth Amendment rights would be compromised, the plaintiff’s interest in moving forward, judicial efficiency, and the public interest.
Common Acts That Produce Both Cases
Any conduct that both violates a criminal statute and causes private harm can generate parallel proceedings. The recurring categories:
- Physical violence. An assault or battery can be prosecuted as a crime. The victim can separately sue for the tort of battery to recover damages for physical and emotional injuries.
- Theft. Taking someone’s property can lead to criminal larceny or theft charges. The owner can also sue civilly for conversion to recover the value of what was taken.
- Fraud. A deception scheme can result in criminal fraud charges. The people who lost money can bring a civil fraud claim to recoup those losses.
- Drunk driving. Operating a vehicle while intoxicated is a crime, and if the driver injures someone, the injured person can sue for negligence.
- Wrongful death. A killing can be prosecuted as manslaughter or murder. The family can file a separate civil wrongful death lawsuit for their loss, even if the criminal case does not end in a conviction.
Each scenario asks two different questions. The criminal case asks whether the defendant should be punished for breaking the law. The civil case asks whether the defendant should pay for the harm caused. The answer to one does not decide the other.
