ETA: { I support the effort to explicitly protect rights in general. Though I’m only slightly in favor of protecting these particular rights, I think you would prefer discussion of effective proposals and language rather than an omnibus debate on the issues. }
First things first, you want to specify that this provision applies to the States (and probably the United States, too). Also a minor change, we do not say rights for people to X, we say rights of people to X.
The right of for two persons legally allowed to enter into contracts to marry shall not be denied or abridged by the United States or any State.
I agree with ctnguy that the language can be interpreted so as to prohibit States from outlawing incestual and polygamous marriages. I would so interpret it. It also appears to prohibit States from outlawing adultery.
As you seem hesitant to make a carveout for incest, I’ll pass over that. For polygamy and adultery, we may qualify the subject as “two unmarried persons”.
The right of two unmarried persons legally allowed to enter into contracts to marry shall not be denied or abridged by the United States or any State.
I agree with UltraVires. There is unnecessary ambiguity in the object of the phrase “to marry”. I would resolve the ambiguity by interpreting “to marry” as modifying “the right” rather than “contracts”, because to do otherwise would render the entire provision nonoperative (Constitutional provisions are entitled to the assumption that they do something).
Nevertheless we can avoid the ambiguity by shifting the sentence structure around.
Neither the United States nor any State shall deny or abridge T the right of two unmarried persons to marry, provided they are legally allowed to enter into contracts to marry shall not be denied or abridged by the United States or any State.
This however does not address UltraVires’s second criticism, which is that the words “legally allowed to enter into contracts” encompass minors. A contract entered into with a minor is not void on its face, although it is not enforceable. Presumably you do not want to prohibit the States from outlawing child marriages.
There are a couple solutions to this problem. First you could prohibit child marriages at a federal level by specifying an age, for example “unmarried persons who are eighteen years of age or older.” Child marriage is controversial and nearly all (40+) States allow minors to marry under certain circumstances, so for the purposes of this post, I won’t include that. You could also replace “legally allowed” with the legal term “competent”, leaving the problem of child marriage in status quo.
Neither the United States nor any State shall deny or abridge the right of two unmarried persons to marry, provided they are competent legally allowed to enter into contracts.
This isn’t perfect language. For one, competency is left to the Supreme Court to define. Although I trust the Court to leave it to States to define “competency”, you may want to do so explicitly. Second, and this goes to the core of your newfound advocacy for explicit rights, the right to enter into contracts isn’t enumerated in the Constitution. The closest thing is the Fourteenth Amendment’s guarantee of due process before States may restrict “liberty”, construed widely so as to encompass the “liberty to contract”. Yet the Courts have ruled that States may use their police powers to infringe on individuals’ liberty to contract, West Coast Hotel Co. v. Parrish, 300 U.S. 379 (1937). That ruling is the basis for State minimum wage laws. The Court reasoned that the State’s interest in each individual’s health, safety, and welfare justified the minimum wage laws just as well as safety regulations. But they also reasoned that the State was justified in restricting women from working long hours because ‘women become objects of public interest and care in order to preserve the strength and vigor of the race’. Id. at 394.
Surely one can argue to restrict the liberty of contract when a same-sex couple seeks a marriage license. Today he would be a sophist; in a world where this amendment is not only prudent but necessary, I would want to protect the right to enter into contracts explicitly.
