According to the Iowa Supreme Court sexual orientation deserves special scrutiny because "gay and lesbian people as a group have long been the victim of purposeful and invidious discrimination as group, there was no evidence that sexual orientation bears any logical relationship" to a person's "ability to perform productively in society." The Iowa court also said that sexual orientation is central to a person's being and that gays and lesbians are not politically powerful enough to overcome the discrimination over sexual orientation.
The court dispatched the arguments made by Polk County with relative ease. For example, it dismissed the best interests of the child argument by noting that the state allows other "less than optimal parents."
Iowa's Supreme Court also addressed the religious issue. It acknowledged that some religious people hold a sincere belief that marriage would undermined by extended marriage rights to gays and lesbians but the court also acknowledged "other equally sincere groups have espused religious views yielding the opposite conclusions." "These contrasting opinions, the court finds, explains the absence of any religious based rationale to Iowa's same-sex marriage stature." The court is also emphatic that this decision relates only to the civil contract known as civil marriage and "does not prescribe a definition of marriage for religious institutions."
This a complete victory for supporters of same sex marriage. The decision was unanimous and Justice Mark Cady, who was appointed by Republican Governor Terry Branstad, wrote the opinion. It is a great day to be in Iowa.
