The most common jury duty cases are personal injury negligence lawsuits on the civil side and assault, drug, and property crime prosecutions on the criminal side, with employment discrimination claims, medical malpractice suits, and breach of contract disputes filling out the rest of the docket. The Sixth Amendment guarantees a jury in criminal prosecutions, and the Seventh Amendment preserves it in civil disputes where the amount at stake exceeds twenty dollars, a threshold set in 1791 that in practice sweeps in nearly every civil case.1Library of Congress.

Personal Injury and Negligence Lawsuits
If one category dominates civil jury dockets, it’s the negligence lawsuit. Someone gets hurt, blames another party’s carelessness, and asks a jury to decide who was at fault and how much money makes it right. Car accidents are the classic scenario. Jurors review police reports, witness statements, and sometimes accident-reconstruction testimony to figure out what happened and who bears responsibility. Premises liability claims, like injuries from a fall at a grocery store or an unsafe stairwell in an apartment building, follow the same framework: did the property owner know about the hazard, and did they do enough to fix it or warn people?
When a jury finds the defendant liable, the work isn’t over. Most states use some form of comparative negligence, so jurors also decide whether the injured person’s own actions contributed to the accident. If the plaintiff was texting while crossing a parking lot and got hit by a car, the jury might assign 20 percent of the fault to the plaintiff, which reduces the damages award by that same percentage. Jurors then calculate compensatory damages for medical bills, lost wages, rehabilitation costs, and pain and suffering. Awards vary enormously, from a few thousand dollars for soft-tissue injuries to millions for permanent disability or traumatic brain injuries.
Criminal Cases Jurors See Most
Criminal trials carry higher stakes and a stricter proof standard. The prosecution must prove every element beyond a reasonable doubt, and jurors are expected to take that obligation seriously. A few categories appear far more often than others.
Assault and Other Violent Offenses
Aggravated assault cases are among the most common violent crimes to reach a jury. These typically involve allegations that the defendant caused serious bodily injury or used a weapon. Jurors weigh physical evidence, medical records, and witness testimony. Sentencing ranges vary widely with the circumstances. Federal law alone sets maximum terms anywhere from three years for assaulting a federal officer to twenty years when the assault causes permanent disfigurement.3United States Sentencing Commission. United States Sentencing Commission Amendment 614 Robbery trials follow a similar pattern but add the element of force or intimidation used to take someone’s property.
Drug Distribution
Drug distribution charges fill criminal dockets across the country. These cases often hinge on whether the quantity of a controlled substance suggests personal use or intent to sell. Jurors evaluate surveillance footage, recorded communications, forensic lab results, and testimony from law enforcement. The credibility of informants and undercover agents frequently becomes the central battleground.
DUI and Property Crimes
Driving under the influence charges reach juries less often than television suggests. Most DUI cases resolve through plea bargains or bench trials, and a handful of states classify DUI as a traffic violation rather than a criminal offense, which eliminates the jury trial option entirely. Contested DUI cases still land before juries, especially when the defendant faces felony charges because of prior convictions or an accident that caused injuries. Property crimes like burglary, theft, and fraud appear regularly as well, particularly when the value of stolen property pushes the charge into felony territory.
Workplace Discrimination and Wrongful Termination
Workplace lawsuits that reach a jury usually involve wrongful termination, discrimination, or harassment claims. The legal foundation for most of these cases is Title VII of the Civil Rights Act of 1964, which prohibits employment discrimination based on race, color, religion, sex, and national origin.4U.S. Equal Employment Opportunity Commission. Title VII of the Civil Rights Act of 1964 The Americans with Disabilities Act adds protections for workers with qualifying disabilities. Jurors in these trials review internal emails, performance evaluations, and HR records to figure out what actually motivated an employer’s decision.
One procedural detail trips up many potential plaintiffs: before you can file a federal discrimination lawsuit, you must first file a charge with the Equal Employment Opportunity Commission. The EEOC investigates and eventually issues a Notice of Right to Sue, at which point you have 90 days to get your case into court. Miss that window and the claim is likely dead regardless of its merits. Age discrimination claims under the ADEA work slightly differently: you can file suit 60 days after submitting your EEOC charge without waiting for a right-to-sue notice.5U.S. Equal Employment Opportunity Commission. Filing a Lawsuit
If a jury finds that an employer acted with malice or reckless indifference, it can award punitive damages on top of back pay and compensation for emotional distress. Testimony from coworkers and supervisors gives jurors a window into the daily workplace environment, and these firsthand accounts often matter more than the paper trail.
Medical Malpractice Trials
Medical malpractice trials are among the most technically demanding cases a juror will face. The core question is straightforward: did a healthcare provider fall below the accepted standard of care, and did that failure directly cause the patient harm? Answering it requires wading through complex medical evidence. Common scenarios include surgical errors, missed diagnoses of conditions like cancer or heart disease, medication mistakes, and birth injuries.
Because jurors aren’t expected to have medical expertise, both sides bring in expert witnesses. The plaintiff’s expert explains what a competent provider should have done; the defense expert argues the provider’s actions were reasonable. Jurors weigh the competing opinions and decide which account is more credible. Successful malpractice verdicts tend to produce large awards because the injuries are often severe and permanent. Average jury verdicts in cases the plaintiff wins exceed $1 million, and so-called nuclear verdicts of $10 million or more have become increasingly common.
Filing deadlines for malpractice claims are shorter than for most other lawsuits. Most states impose a statute of limitations of two to three years, and many apply a discovery rule that starts the clock when the patient knew or should have known about the injury rather than when the medical error occurred. An outer limit, often called a statute of repose, bars claims after a fixed number of years regardless of when the injury was discovered. Miss these deadlines and the case never reaches a jury.
Breach of Contract Disputes
Contract disputes round out the list. A breach of contract claim comes down to two questions: did one party fail to hold up their end of the deal, and did that failure cause the other side measurable financial harm? These cases range from partnership blowups and real estate deals gone sideways to vendors who failed to deliver goods or services as promised.
Jurors examine the contract language, financial records, invoices, and correspondence to pinpoint where the relationship broke down. Damages in a contract case are meant to put the non-breaching party in the position they would have occupied if the contract had been honored. That usually means compensation for documented losses like unpaid invoices, cost overruns from hiring a replacement, or lost profits from the broken deal.
Some contracts include a liquidated damages clause that sets a predetermined penalty for breach. Courts generally enforce these clauses only when two conditions are met: the actual damages would have been difficult to estimate when the contract was signed, and the predetermined amount is reasonable compared to the anticipated or actual harm. If the figure looks like a punishment rather than a fair estimate of loss, a court may throw out the clause as an unenforceable penalty. Jurors may need to decide whether the agreed amount passes that reasonableness test.
Civil Versus Criminal Proof Standards
The proof standard shifts dramatically depending on which side of the docket you’re on, and jurors are instructed on exactly what the plaintiff or prosecution has to prove. In civil cases, a plaintiff only needs to show that their version of events is more likely true than not, a standard called preponderance of the evidence. Think of it as tipping the scales just past halfway. Criminal cases require proof beyond a reasonable doubt, a much steeper hill. That gap explains why someone can be acquitted in criminal court but still lose a civil lawsuit arising from the same incident.
Jury Size and Unanimity
Federal criminal trials use 12-person juries, and the verdict must be unanimous. The Supreme Court confirmed in Ramos v. Louisiana (2020) that the Sixth Amendment requires unanimity in state criminal trials as well, striking down the last two states that had allowed split verdicts.6Supreme Court of the United States. Ramos v. Louisiana, 590 U.S. 83 (2020)
Federal civil trials operate under slightly different rules. A civil jury must have at least six members and can have up to twelve, and the verdict must be unanimous unless both parties agree otherwise.7Legal Information Institute. Federal Rules of Civil Procedure Rule 48 – Number of Jurors; Verdict; Polling State civil trials have the most variation: roughly half of states allow non-unanimous verdicts in civil cases, with thresholds like five out of six or nine out of twelve depending on the jurisdiction.
