Thi question is incomplete. Here´s the complete question.
The 2013 case of Windsor v. United States in the Second Circuit Court of Appeals employed ___ in holding that the Defense of Marriage Act held no legitimate state interest and thus overturned it.
Answer: intermediate scrutiny
Explanation:
In United States v. Windsor, the Second Circuit Court of Appeals confirmed the lower court's decision that Section 3 of DOMA was unconstitutional.
The court found that, since homosexuals had been historically subjected to discrimination, they could be considered as a group that falls under a "quasi-suspect classification", and therefore intermediate scrutiny could be applied.
DOMA was deemed unconstitutional under the equal protection guarantees of the Fifth Amendment because it didn´t pass that test.
