Neither the jury nor the judge is universally "more powerful"; they have distinct roles, but in most criminal trials, the jury holds the ultimate power to decide guilt or innocence (the verdict), while the judge controls the legal process, determines what evidence is admitted, and imposes the sentence. The jury acts as the finder of fact and applies the law as instructed, but the judge ensures fairness, manages evidence (ruling on objections), and interprets the law, making them powerful in shaping the trial's direction and outcome.

In civil cases, requirements vary by state, but often fewer than 12 jurors agree, and some states allow non-unanimous verdicts, but a complete deadlock still results in a mistrial.
