The case of William Marbury against the secretary of state James Madison is an important case in the history of the United States Supreme Court. When Adams was not reelected, he appointed many judges before Jefferson took office. these are referred to as midnight judges for he was staying up until the midnight before the inauguration appointing the judges. William Marbury was one. When the new sec. of state refused to give him the job, he sued. Although they agreed he should get the job, they could not make Madison give it to him. While reviewing the case and the laws applied, they ruled a law to be unconstitutional. This established judicial review which still plays a part in our legal system. This is how the supreme court can rule a law unconstitutuional when it is reviewed during a case.
