It puts the power to decide guilt not in the hands of the state, but of ordinary citizens. Twelve regular people, the founders believed, were a better safeguard of liberty than any judge or official alone.
A jury is a group of citizens sworn to hear the evidence in a trial and decide the facts, most importantly, whether a defendant is guilty. It places that momentous judgment with ordinary people rather than with the government alone.
The right to it is constitutional. The Sixth Amendment guarantees a jury in criminal cases, the Seventh in many civil ones. The framers, deeply suspicious of government power, saw the jury as a vital check, a piece of the judicial system placed directly in the people's hands.
It has ancient roots and a fierce protective history. Descended from English common law, the jury was prized as a bulwark against tyranny, a body the crown could not simply command. A famous 1670 English case established that jurors could not be punished for their verdict, securing their independence.
It holds a quiet, radical power. A jury can acquit against the evidence, a power called nullification, effectively refusing to enforce a law it finds unjust. This makes the jury not just a fact-finder but a final, citizen-held check on the law itself.
