DES MOINES, Iowa (AP) âÄî Iowa’s Supreme Court legalized gay marriage Friday in a unanimous and emphatic decision that makes Iowa the third state âÄî and first in the nation’s heartland âÄî to allow same-sex couples to wed. Iowa joins only Massachusetts and Connecticut in permitting same-sex marriage. For six months last year, California’s high court allowed gay marriage before voters banned it in November. The Iowa justices upheld a lower-court ruling that rejected a state law restricting marriage to a union between a man and woman. The county attorney who defended the law said he would not seek a rehearing. The only recourse for opponents appeared to be a constitutional amendment, which could take years to ratify. “We are firmly convinced the exclusion of gay and lesbian people from the institution of civil marriage does not substantially further any important governmental objective,” the Supreme Court wrote. Iowa lawmakers have “excluded a historically disfavored class of persons from a supremely important civil institution without a constitutionally sufficient justification.” To issue any other decision, the justices said, “would be an abdication of our constitutional duty.” The Iowa attorney general’s office said gay and lesbian couples can seek marriage licenses starting April 24, once the ruling is considered final. “Iowa is about justice, and that’s what happened here today,” said Laura Fefchak, who awaited the decision at a party in the Des Moines suburb of Urbandale. Her partner of 13 years, Nancy Robinson, added: “To tell the truth, I didn’t think I’d see this day.” Des Moines attorney Dennis Johnson, who argued on behalf of gay and lesbian couples, said “this is a great day for civil rights in Iowa.” “We have all of you courageous plaintiffs to thank: Go get married, live happily ever after, live the American dream,” he said. In its decision, the Supreme Court upheld an August 2007 decision by a judge who found that a state law limiting marriage to a man and a woman violates the constitutional rights of equal protection. The Polk County attorney’s office claimed that Judge Robert Hanson’s ruling violated the separation of powers and said the issue should be left to the Legislature. The case had been working its way through the courts since 2005, when Lambda Legal, a New York-based gay rights organization, filed a lawsuit on behalf of six gay and lesbian couples in Iowa. The Supreme Court noted that any new distinction based on sexual orientation “would be equally suspect and difficult to square” with the state’s constitution. John Logan, a sociology professor at Brown University, said Iowa’s status as a largely rural, Midwest state could enforce an argument that gay marriage is no longer a fringe issue. “When it was only California and Massachusetts, it could be perceived as extremism on the coasts and not related to core American values. “But as it extends to states like Iowa, and as attitudes toward gay marriage have evidently changed, then people will look at it as an example of broad acceptance,” Logan said. Polk County Attorney John Sarcone said his office will not ask for the case to be reconsidered. “Our Supreme Court has decided it, and they make the decision as to what the law is, and we follow Supreme Court decisions,” Sarcone said. Gay marriage opponents have no other legal options to appeal the case to the state or federal level because they were not parties to the lawsuit, and there is no federal issue raised in the case, Sarcone said. Bryan English, spokesman for the Iowa Family Policy Center, a conservative group that opposes same-sex marriage, said many Iowans are disappointed with the ruling and do not want courts to decide the issue. “I would say the mood is one of mourning right now in a lot of ways,” English said. He said the group immediately began lobbying legislators “to let the people of Iowa vote” on a constitutional amendment. “This is an issue that will define (lawmakers’) leadership. This is not a side issue.” Iowa has a history of being in the forefront on social issues. It was among the first states to legalize interracial marriage and to allow married women to own property. It was also the first state to admit a woman to the bar to practice law and was a leader in school desegregation. Todd Pettys, a University of Iowa law professor, said the state’s equal protection clause on which Friday’s ruling was based is worded slightly differently than the U.S. Constitution. But Iowa’s language means almost “exactly the same thing.” Still, he said, it’s difficult to predict whether the U.S. Supreme Court would view the issue the same way as the Iowa justices. Linda McClain, professor at Boston University School of Law, said she doubted Iowa’s ruling would be “a realistic blueprint” for the U.S. Supreme Court,” particularly considering the court’s conservative leadership. Senate Majority Leader Mike Gronstal, a Democrat, said state lawmakers were unlikely to consider gay marriage legislation in this legislative session, which is expected to end within weeks. Gronstal also said he’s “not inclined” to propose a constitutional amendment during next year’s session. Iowa’s Democratic governor, Chet Culver, said he would review the decision before announcing his views.
