Although the purposes of a civil lawsuit and a criminal prosecution are quite different, the issues in related civil and criminal cases may be very similar. For instance, in a car accident case, a defendant may be criminally prosecuted for driving under the influence of alcohol and may also be sued civilly for negligently or recklessly causing a motor vehicle accident while intoxicated.
In the criminal case, the court may order the defendant to pay a fine, perform community service, or be incarcerated. In the civil case, the court may hold the defendant liable for damages resulting from the car accident and order the defendant (or, in actuality, their insurance company) to pay money to the plaintiff in compensation for their medical expenses, lost wages, and pain and suffering associated with the accident.
Recently, the state supreme court clarified the issue of whether a judgment of conviction in a criminal case could be used as evidence by the plaintiff in a civil case.
