The correct answer is Plessy Vs. Ferguson. In the landmark case Plessy vs. Ferguson, it was ruled that segregation of facilities was constitutional as long as those facilities were equal in quality. This is were the term "Separate but Equal" comes from. However, during the case Brown vs. The Board of Education it was ruled that racial segregation violated the fourteenth amendment of the Constitution. It was this ruling that rendered the ruling in Plessy vs. Ferguson invalid because the ruling was unconstitutional.
Answer:
It can veto laws passed by the legislative branch.
Explanation:
The ability to veto a certain law is held by the President of United States (the president is part of the executive branch)
Whenever the legislative branch created a law that does not have at least 67% of the legislators, the president had the ability to veto it. When the law is vetoed, the law wouldn't be able to be enacted into law unless the legislators made some change/adjustment that the president asked for.
The president may serve a maximum of 2 terms.
