Here is the .pdf of the CT Supreme Court decision, which includes this remarkable language:
Although we acknowledge that many legislators and many of their constituents hold strong personal convictions with respect to preserving the traditional concept of marriage as a heterosexual institution, such beliefs, no matter how deeply held, do not constitute the exceedingly persuasive justification required to sustain a statute that discriminates on the basis of a quasi-suspect classification. “That civil marriage has traditionally excluded same-sex couples, i.e., that the ‘historic and cultural understanding of marriage’ has been between a man and a woman’ cannot in itself provide a [sufficient] basis for the challenged exclusion. To say that the discrimination is ‘traditional’ is to say only that the discrimination has existed for a long time. A classification, however, cannot be maintained merely ‘for its own sake’ [Romer v.Evans, supra, 517 U.S. 635].
Instead, the classification ([that is], the exclusion of gay [persons] from civil
marriage) must advance a state interest that is separate from the classification itself [see id., 633, 635]. Because the ‘tradition’ of excluding gay [persons] from civil marriage is no different from the classification itself, the exclusion cannot be justified on the basis of ‘history.’ Indeed, the justification of ‘tradition’ does not explain the classification; it merely repeats it. Simply put, a history or tradition of discrimination – no matter how entrenched – does not make the discrimination constitutional.”
The boldface is mine. Stunning. The ruling also clarified that civil union is not the same.
