Answer:
B
Step-by-step explanation:
In the case of Marbury v. Madison, Jonh Marshall said that he could not give a ruling because the law that allowed this case to be in the supreme court was unconstitutional. This had never been done before, no person had openly spoken against a law not because they didn't like it, but because it was unconstitutional. This case created the judicial review and is the reason that today it is the Supreme Courts' responsibility to decide whether or not laws are constitutional.
