485 U.S. 386

We granted the Secretary of Health and Human Services’ petition for certiorari, 479 U.S. 1083, 107 S.Ct. 1282, 94 L.Ed.2d 141 (1987), in order to review the judgment of the Court of Appeals for the Ninth Circuit that the Secretary unlawfully rejected a California Medicaid plan amendment because an internal agency manual stating approval of the type of provision in question was a binding regulation, and because acceptance of the amendment was required by ? 2373(c) of the Deficit Reduction Act of 1984, Pub.L. 98-369, 98 Stat. 1112, note following 42 U.S.C. ? 1396a (1982 ed., Supp. III). Cubanski v. Heckler, 781 F.2d 1421 (1986). After the case had been briefed and argued, Congress enacted ? 4106 of the Omnibus Budget Reconciliation Act of 1987, Pub.L. 100-203, 101 Stat. 1330, which required the Secretary to approve the proposed California amendment, retroactively to the date of its proposal. The Secretary has complied with that requirement.

The parties agree that these developments have rendered the controversy moot. In accordance with our established practice, we vacate the judgment of the Ninth Circuit and remand with instructions to dismiss the suit. See Deakins v. Monaghan, 484 U.S. 193, 200, 204, 108 S.Ct. 523, 528, 531, 98 L.Ed.2d 529 (1988); United States v. Munsingwear, Inc., 340 U.S. 36, 39-40, 71 S.Ct. 104, 106-107, 95 L.Ed. 36 (1950).

It is so ordered.

Justice KENNEDY took no part in the consideration or decision of this case.
