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:
WHEELER et al. v. MONTGOMERY, DIRECTOR, DEPARTMENT OF SOCIAL WELFARE OF CALIFORNIA, et al.
No. 14.

Peter E. Sitkin argued the cause for appellants. With him on the briefs were Steven J. Antler and Charles Stephen Ralston.
Elizabeth Palmer, Deputy Attorney General of California, argued the cause for appellees. With her on the brief were Thomas C. Lynch, Attorney General, Richard L. Mayers, Deputy Attorney General, Thomas M. O’Connor, and Raymond D. Williamson, Jr.

Mr. Justice Brennan
delivered the opinion of the Court.
This is a companion case to No. 62, Goldberg v. Kelly, ante, p. 254. It is a class action brought by all recipients of old age benefits who are subject to California welfare termination provisions. A three-judge District Court for the Northern District of California held that the California procedure for pre-termination review in welfare cases satisfies the requirements of the Due Process Clause, 296 F. Supp. 138 (1968), and we noted probable jurisdiction, 394 U. S. 970 (1969). This procedure requires notice to the recipient of the proposed discontinuance or suspension at least three days prior to its effective date, together with reasons for the intended action and a statement of what information or action is required to re-establish eligibility, advice that the recipient may meet his caseworker before his benefits are terminated “[t]o discuss the entire matter informally for purposes of clarification and, where possible, resolution,” and assurance that there will be “prompt investigation” of the case and restoration of payments “as soon as there is eligibility” to receive them. The procedure does not, however, afford the recipient an evidentiary hearing at which he may personally appear to offer oral evidence and confront and cross-examine the witnesses against him. In Goldberg v. Kelly, supra, decided today, we held that procedural due process requires such an evidentiary pre-termination hearing before welfare payments may be discontinued or suspended. Accordingly, the judgment of the District Court must be and is reversed on the authority of Goldberg v. Kelly.
Reversed.
Mr. Justice Black, for the reasons set forth in his dissenting opinion in No. 62, Goldberg v. Kelly, ante, p. 271, dissents and would affirm the judgment below.
California State Department of Social Welfare, Public Social Services Manual, Reg. 44-325 (effective April 1, 1968). The pertinent provisions of the regulation state:
“.43 . . . The recipient . . . shall be notified,, in writing, immediately upon the initial decision being made to withhold a warrant beyond its usual delivery date . . . and in no case less than three . . . mail delivery days prior to the usual delivery date of the warrant .... The county shall give such notice as it has reason to believe will be effective including, if necessary, a home call by appropriate personnel. . . . Every notification shall include:
“.431 A statement setting forth the proposed action and the grounds therefor, together with what information, if any, is needed or action required to reestablish eligibility ....
“.432 Assurance that prompt investigation is being made; that the withheld warrant will be delivered as soon as there is eligibility to receive it; and that the evidence or other information which brought about the withholding action will be freely discussed with the recipient . . . if he so desires ....
“.434 A statement that the recipient . . . may have the opportunity to meet with his caseworker ... in the county department, at a specified time, or during a given time period which shall not exceed three . . . working days, and the last day of which shall be at least one . . . day prior to the usual delivery date of the warrant, and at a place specifically designated in order to enable the recipient . . .
“(a) To learn the nature and extent of the information on which the withholding action is based;
“(b) To provide any explanation or information, including, but not limited to that described in the notification . . . ;
“(c) To discuss the entire matter informally for purposes of clarification and, where possible, resolution.”
