It certainly is true.


No state shall enter into any treaty, alliance, or confederation; grant letters of marque and reprisal; coin money; emit bills of credit; make any thing but gold and silver coin a tender in payment of debts; pass any bill of attainder, ex post facto law, or law impairing the obligation of contracts, or grant any title of nobility.
United States Constitution, Art 1, Sec 10, Cl 1

[Sir Francis Dashwood]

Here is the law... pay attention to the bold typeface.

Article IV.

Section. 1.

Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof.

Only Congress can define the effect by law... Article I says nothing about Congress...
