Judicial Review is an idea stating that the constitution can overrule the supreme court's powers.
In the Election of 1800, Jefferson beat out Adams for United States President
Adams decided to make one last move before he left. He appointed a bunch of his Federalist friends to the Supreme Court. The Senate approved and they became the new judges.
Secretary Madison, as the president I command you to stop the commission letters that appoint the new judges from arriving.
Yes sir, I can do that!
I am William Marbury. I am supposed to be sworn in as a Supreme Court Justice! Mr. James Madison stole my commission and now I can't become I justice. I demand a court order. Madison should give me my letter!
Mr. Marbury. I agree that your wrong should be righted. However, I don't have the power to make Madison give you the commission. We, as the Supreme court have powers the constitution said we shouldn't have. The constitution is the supreme law.
