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:
CARTER et al. v. WEST FELICIANA PARISH SCHOOL BOARD et al.
No. 944.
Decided January 14, 1970
Richard B. Sobol, Murphy W. Bell, Robert F. Collins, Norman C. Amaker, and Melvyn Zarr for petitioners in No. 944. Jack Greenberg, James M. Nabrit III, Mr. Amaker, Mr. Zarr, Oscar W. Adams, Jr., John H. Ruffin, Jr., and Earl M. Johnson for petitioners in No. 972.
John F. Ward, Jr., for respondents in No. 944. Robert C. Cannada and Thomas H. Watkins for Jackson Municipal Separate School District et al., Hardy Lott for Marshall County Board of Education, Reid B. Barnes for Jefferson County Board of Education, Edwin L. Brobston for Board of Education of the City of Bessemer et al., Palmer Pillans and George F. Wood for Board of School Commissioners of Mobile County et al., Frank C. Jones and Wallace Miller, Jr., for Bibb County Board of Education et al., H. A. Aultman for Houston County Board of Education, W. Fred Turner for Board of Public Instruction of Bay County, and Sam T. Dell, Jr., for Board of Public Instruction of Alachua County et al., respondents in No. 972.
Briefs of amici curiae in Nos. 944 and 972 were filed by Solicitor General Griswold for the United States, and by Mr. Ward for the Louisiana Teachers Association. Rivers Buford, Jr., and Gerald Mager filed a brief for the State Board of Education of Florida as amicus curiae in No. 972.
Together with No. 972, Singleton et al. v. Jackson Municipal Separate School District et al., also on petition for writ of certiorari to the same court.
Per Curiam.
Insofar as the Court of Appeals authorized deferral of student desegregation beyond February 1, 1970, that court misconstrued our holding in Alexander v. Holmes County Board of Education, ante, p. 19. Accordingly, the petitions for writs of certiorari are granted, the judgments of the Court of Appeals are reversed, and the cases remanded to that court for further proceedings consistent with this opinion. The judgments in these cases are to issue forthwith.
