This case is difficult because it couples issues of equal protection and federalism with the need to assess the rationale for a congressional statute passed with minimal hearings and lacking in formal findings. In addition, Supreme Court precedent offers some help to each side, but the rationale in several cases is open to interpretation. We have done our best to discern the direction of these precedents, but only the Supreme Court can finally decide this unique case.
Although our decision discusses equal protection and federalism concerns separately, it concludes that governing precedents under both heads combine--not to create some new category of "heightened scrutiny" for DOMA under a prescribed algorithm, but rather to require a closer than usual review based in part on discrepant impact among married couples and in part on the importance of state interests in regulating marriage.Describing recent Supreme Court equal protection decisions, the 1st Circuit said:
In a set of equal protection decisions, the Supreme Court has now several times struck down state or local enactments without invoking any suspect classification. In each, the protesting group was historically disadvantaged or unpopular, and the statutory justification seemed thin, unsupported or impermissible.Concluding that "Congress' denial of federal benefits to same-sex couples lawfully married in Massachusetts has not been adequately supported by any permissible federal interest," the court explained:
In reaching our judgment, we do not rely upon the charge that DOMA's hidden but dominant purpose was hostility to homosexuality. The many legislators who supported DOMA acted from a variety of motives, one central and expressed aim being to preserve the heritage of marriage as traditionally defined over centuries of Western civilization. ...
For 150 years, this desire to maintain tradition would alone have been justification enough for almost any statute.... But Supreme Court decisions in the last fifty years call for closer scrutiny of government action touching upon minority group interests and of federal action in areas of traditional state concern.
To conclude, many Americans believe that marriage is the union of a man and a woman, and most Americans live in states where that is the law today. One virtue of federalism is that it permits this diversity of governance based on local choice, but this applies as well to the states that have chosen to legalize same-sex marriage.CNN reports on the decision.
