It is the one time the government compels an ordinary citizen to wield real power over another person's fate. Most people dread the summons. It is one of the purest acts of self-government there is.
Jury duty is the obligation of citizens to serve on a jury when called, deciding the facts in criminal and civil trials. It is one of the few direct duties the republic asks of nearly every adult citizen, alongside obeying the law and paying taxes.
It puts power in ordinary hands. Rather than leaving guilt or liability to be decided by the state alone, the jury system places that judgment with a group of regular citizens. The right to a jury is guaranteed by the Sixth Amendment in criminal cases and the Seventh in many civil ones.
It is a check on government power. A jury can refuse to convict even when the evidence is clear, a power sometimes called jury nullification, which acts as a community veto against laws or prosecutions the jurors find unjust.
It is also a great equalizer. The summons arrives regardless of wealth or status. For a few days, a random citizen holds binding authority over a fellow human being's liberty or property, a responsibility the founders trusted to the people rather than to officials alone.
