 The marriage amendment validated HRS § 572-1 by taking the statute out of the ambit of the equal protection clause of the Hawaii Constitution, at least insofar as the statute, both on its face and as applied, purported to limit access to the marital status to opposite-sex couples.Accordingly, whether or not in the past it was violative of the equal protection clause in the foregoing respect, HRS § 572-1 no longer is.In light of the marriage amendment, HRS § 572-1 must be given full force and effect."
