ceedings before this Court. The judgment in question orders the United States to pay Windsor the refund she seeks. An order directing the Treasury to pay money is "a real and immediate economic injury," Hein, 551 U.S., at 599, indeed as real and immediate as an order directing an individual to pay a tax. That the Executive may welcome this order to pay the refund if it is accompanied by the constitutional ruling it wants does not eliminate the injury to the national Treasury if payment is made, or to the taxpayer if it is not. The judgment orders the United States to pay money that it would not disburse but for the court's order. The Government of the United States has a valid legal argument that it is injured even if the Executive disagrees with §3 of DOMA, which results in Windsor's liability for the tax. Windsor's ongoing claim for funds that the United States refuses to pay thus establishes a controversy sufficient for Article III jurisdiction. It would be a different case if the Executive had taken the further step of paying Windsor the refund to which she was entitled under the District Court's ruling.
This Court confronted a comparable case in INS v. Chadha, 462 U.S. 919 (1983). A statute by its terms allowed one House of Congress to order the Immigration and Naturalization Service (INS) to deport the respondent Chadha. There, as here, the Executive determined that the statute was unconstitutional, and "the INS presented the Executive's views on the constitutionality of the House action to the Court of Appeals." Id., at 930. The INS, however, continued to abide by the statute, and "the INS brief to the Court of Appeals did not alter the agency's decision to comply with the House action ordering deportation of Chadha." Ibid. This Court held "that the INS was sufficiently aggrieved by the Court of Appeals decision prohibiting it from taking action it would otherwise take," ibid., regardless of whether the agency welcomed the judgment. The necessity of a "case or controversy" to
