What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
UNITED STATES v. BUFFALO SAVINGS BANK.
No. 96.
Argued December 3, 1962.—
Decided January 7, 1963.
John B. Jones, Jr. argued the cause for the United States. On the briefs were Solicitor General Cox, Assistant Attorney General Oberdorfer, Stephen J. Poliak, Joseph Kovner and George F. Lynch.
John Horace Little argued the cause and filed briefs for respondent.
Laurens Williams and William Poole filed a brief for the American Bar Association, as auiicus curiae, urging affirmance.
Per Curiam.
In 1946, respondent Buffalo Savings Bank made a loan secured by a real estate mortgage. The United States filed notice of a federal tax lien against the mortgagor’s property in 1953. Thereafter, in 1957 and 1958, liens for unpaid real estate taxes and other local assessments attached to the property. The bank instituted foreclosure proceedings, naming the United States as a party. The trial court’s decree ordered the property sold and the payment of local real estate taxes and other assessments as part of the expenses of the sale prior to the satisfaction of the tax lien of the United States. The United States appealed and the New York Supreme Court, Appellate Division, reversed, only to be reversed in turn by the New York Court of Appeals, which reinstated the trial court’s judgment on the ground that the federal tax lien attached only to the mortgagor’s interest in the surplus after the foreclosure sale and therefore was subordinate to the local taxes as “expenses of sale.” 11 N. Y. 2d 31, 181 N. E. 2d 413.
We must reverse the judgment of the New York Court of Appeals for failure to take proper account of United States v. New Britain, 347 U. S. 81. That case rules this one, for there the Court quite clearly held that federal tax liens have priority over subsequently accruing liens for local real estate taxes, even though the burden of the local taxes in the event of a shortage would fall upon the mortgagee whose claim under state law is subordinate to local tax liens.
A similar argument based on the general character of the ■ federal tax lien was made and specifically rejected in New Britain. Moreover, the state may not avoid the priority rules of the federal tax lien by the formalistic device of characterizing subsequently accruing local liens as expenses of sale. Cf. United States v. Gilbert Associates, Inc., 345 U. S. 361. Finally, respondent’s reliance on United States v. Brosnan, 363 U. S. 237, and Crest Finance Co. v. United States, 368 U. S. 347, is misplaced. Brosnan was concerned with foreclosure procedures, not with priorities, and in connection with the latter subject relied upon New Britain among other cases. Crest is wholly inapposite here.
The judgment is therefore reversed and the cause remanded for further proceedings not inconsistent with this opinion.
Reversed and remanded.
Mr. Justice Douglas dissents.
