In the near term, the question about same sex marriages seems to be centered on the equal protection clause of the 14th amendment. Eventually, I believe the supreme court will need to address a 13th amendment question about marriages in general. Does state recognition of marriage as providing special autonomy to individuals shielded from state interference violate the 13th amendment’s prohibitions against slavery and (implicitly) indentured servitude? While religious recognition of marriage is legitimate and may vary, the state may be justified in not recognizing any marriages so that it will continue to be able to protect against abusive labor arrangements. The equal protections of the 14th amendment applies also to the prohibitions of slavery of the 13th amendment. Taken together, the two amendments should prohibit that states from offering any special recognition and privileges to marriages that are not also available to more routine corporate charters.
