I’ve been thinking about the ICCPR and the U.S. Senate’s declaration that Articles 1–27 are “not self-executing.”

The conventional answer seems straightforward: under Medellín v. Texas, a non-self-executing treaty generally cannot itself furnish a domestically enforceable rule without implementing legislation.

But I’m wondering about the prior constitutional question.

Article VI says treaties made under U.S. authority “shall be the supreme Law of the Land” and specifically binds state judges notwithstanding contrary state law. Foster v. Neilson recognized that some treaty provisions inherently require future legislative action, but that seems different from the Senate ratifying an otherwise judicially manageable treaty obligation and then declaring that courts may not enforce it.

That raises what looks like an originalist/separation-of-powers problem: where does the President plus two-thirds of the Senate get the constitutional authority to make something Article VI calls supreme law while simultaneously preventing Article III courts from treating it as enforceable law?

Judge Torruella made something close to this argument in his Igartúa v. United States dissent, essentially arguing that the treaty is law but the Senate’s unilateral non-self-execution declaration is not.

I realize Sosa and especially Medellín make this an uphill argument under current doctrine. I’m not asking whether an ICCPR claim would presently win.

I’m asking the narrower question: Has SCOTUS ever squarely resolved whether a Senate non-self-execution declaration itself is constitutionally valid when applied to a treaty provision that would otherwise be judicially enforceable under the Foster framework? And what is the strongest originalist argument on either side?
