How can you say banning same-sex marriage is unconstitutional when marriage isn’t in the Constitution? Well, here’s one example from the Iowa Supreme Court, which decided the state’s statute limiting civil marriage to a union between a man and a woman unconstitutional. The comparison can be made given that the Iowa Constitution and the United States Constitution both have equal protection clauses.
IN THE SUPREME COURT OF IOWA
No. 07–1499
Filed April 3, 2009
“Defendant appeals from district court summary judgment ruling holding state statute limiting civil marriage to a union between a man and a woman unconstitutional. AFFIRMED.”
“In this case, we must decide if our state statute limiting civil marriage to a union between a man and a woman violates the Iowa Constitution, as the district court ruled. On our review, we hold the Iowa marriage statute violates the equal protection clause of the Iowa Constitution. Therefore, we affirm the decision of the district court.”
“VI. Conclusion.
The district court properly granted summary judgment to plaintiffs. Iowa Code section 595.2 violates the equal protection provision of the Iowa Constitution. Our decision becomes effective upon issuance of procedendo.
AFFIRMED.
All justices concur.”
