The Supreme Court justices have been deciding cases since the late 1700s.
At times, they have reversed a law that didn’t follow the Constitution. At times, the Constitution may be changed or amended. So the justices’ decision is reversed. And at times, the justices may reverse their own decisions.
Supreme Court decisions usually depend on precedents. These are decisions that have come before. Notable justices have written opinions that reinforce or reverse precedents. Their opinions are like voices in a conversation through time
