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. …The plaintiffs produced evidence to demonstrate sexual orientation and gender have no effect on children raised by same-sex couples, and same-sex couples can raise children as well as opposite-sex couples. They also submitted evidence to show that most scientific research has repudiated the commonly assumed notion that children need opposite-sex parents or biological parents to grow into well-adjusted adults. Many leading organizations, including the American Academy of Pediatrics, the American Psychiatric Association, the American Psychological Association, the National Association of Social Workers, and the Child Welfare League of America, weighed the available research and supported the conclusion that gay and lesbian parents are as effective as heterosexual parents in raising children. …When individuals invoke the Iowa Constitution’s guarantees of freedom and equality, courts are bound to interpret those guarantees. In carrying out this fundamental and vital role, “we must never forget that it is a constitution we are expounding.” M’Culloch v. Maryland, 17 U.S. (4 Wheat.) 316, 407, 4 L. Ed. 579, 602 (1819). It speaks with principle, as we, in turn, must also. See State v. Wheeler, 34 P.3d 799, 807 (Wash. 2001) (Sanders, J., dissenting).
