  PeR Curiam.
  Appellees commenced this action in the federal District Court for the Southern District of New York challenging on equal protection and statutory grounds § 131-a of the New York Social Services Law which provides for payments to welfare recipients in Nassau, Suffolk, and certain other New York State counties in lesser amounts than provided for residents of New York City should the Welfare Administrator determine that adequate cause exists for the differential. A three-judge court was convened and it found that appellees’ likelihood of success on their constitutional claim warranted the issuance of a preliminary injunction against what it found to be the payment of welfare in violation of the Equal Protection Clause of the Fourteenth Amendment. The court found it unnecessary to consider appellees’ statutory claims. We noted probable jurisdiction. 397 U. S. 903.
  Subsequent to the decision of the District Court this Court rendered its decision in Rosado v. Wyman, 397 U. S. 397, wherein we held that a federal court called upon to pass upon the constitutional validity of a State’s welfare program should, before reaching the constitutional issues, consider first any pendent statutory claims that are presented, notwithstanding the pendency of negotiations between the State and the Department of Health, Education, and Welfare.
  In light of the foregoing, the judgment of the District Court is vacated and the case is remanded to that court for an opportunity to pass on the propriety of granting interim relief in accordance with conventional equitable principles on the basis of appellees’ statutory claims, or, if the question is reached, continuing the present injunction in light of this Court’s decision in Dandridge v. Williams, 397 U. S. 471.
  It is so ordered.
  Mr. Justice Marshall took no part in the decision of this case.
