With California's supreme court considering exactly the same thing for pretty much exactly the same reasons this is good news.
DES MOINES, Iowa – The Iowa Supreme Court issued a unanimous ruling Friday finding that the state's same-sex marriage ban violates the constitutional rights of gay and lesbian couples, making Iowa the third state where gay marriage is legal.
In its decision, the court upheld a 2007 district court judge's ruling that the law violates the state constitution. It strikes the language from Iowa code limiting marriage to only between a man a woman.
"The court reaffirmed that a statute inconsistent with the Iowa constitution must be declared void even though it may be supported by strong and deep-seated traditional beliefs and popular opinion," said a summary of the ruling issued by the court.
