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:
BAKER et al. v. TEXAS & PACIFIC RAILWAY CO.
No. 363.
Argued March 25, 1959.
Decided April 6, 1959.
Harvey L. Davis argued the cause and filed a brief for petitioners.
D. L. Case argued the cause and . filed a brief for respondent.
Per Curiam.
This action was commenced by the petitioners against the respondent railroad in a Texas State District Court, under the Federal Employers’ Liability Act; 35 Stat.'65, as amended, 45 U. S. C. §§51-60, to recover-damages for the death of petitioners’ decedent, Claude Baker, allegedly caused by the negligence of the respondent. Baker had been hired as a workman by W. H. Nichols & Co., Inc., which was engaged in work along the main line right of way of the respondent under a contract with it. The work consisted of “grouting,” or pumpipg sand and cement into the roadbed to strengthen and stabilize it. Baker was struck and killed by a train while engaged at this job. It was petitioners’ contention in the trial court that Baker was killed while he was “employed” by respondent, within the meaning of § 1 of the Act. Evidence on the question was introduced by the parties, and a special issue for the jury’s determination was framed, but thé judge declined to submit the issue to the jury, holding as a matter of law that Baker was not in such a relationship to the railroad at the time of his death as tp entitle him to the protection of the Act. The Court of Civil Appeals affirmed the trial court’s judgment for the respondent, 309 S. W. 2d 92, and the Texas Supreme Court refused an application for a writ of error. We granted certiorari, 358 U. S. 878, to investigate whether such an issue is properly one for determination by the. jury.
The Federal Employers’ Liability Act does not use the terms “employee” and “employed” in any special sense, Robinson v. Baltimore & Ohio R. Co., 237 U. S. 84, 94, so that the familiar general legal problems as to whose “employee” or “servant” á worker is at a given time pre-seht themselves as matters of federal law under the Act. See Linstead v. Chesapeake & Ohio R. Co., 276 U. S. 28, 33-34. It has been well said of the question that “ [e] ach case must be decided on its peculiar facts and ordinarily no one feature of the relationship is determinative.” Cimorelli v. New York Central R. Co., 148 F. 2d 575, 577. Although we find no decision of this Court that-has discussed the matter, we think it perfectly plain that the •question, like that of fault or of causation under the Act, contains factual elements such as to make it one for the jury under appropriate instructions as to the various relevant factors under law. See Restatement, Agency 2d, § 220, comment c; § 227, comment a. Only if reasonable men could not reach'differing conclusions on the issue may the question be taken from the jury. See Chicago, R. I. & P. R. Co. v. Bond, 240 U. S. 449. Here the petitioners introduced evidence tending to prove that the grouting work was part of the maintenance task of the railroad; that the road furnished the material to be pumped into the roadbed; and that a supervisor, admittedly in the employ of the railroad, in the daily course of the work exercised directive control over the details of the job performed by the individual workmen, including the precise point where the mixture should be pumped, when they should move to the next point, and the consistency of the mixture. The railroad introduced evidence tending to controvert this and further evidence tending to show that an employment relationship did not exist between it and Baker at the time of the accident. An issue for determination by the jury was presented. “The very essence of . . . [the jury’s] function is to select from among conflicting inferences and conclusions that which it considers most reasonable.” Tennant v. Peoria & Pekin Union R. Co., 321 U. S. 29, 35.
Reversed.
Mr. Justice Frankfurter would dismiss this writ of certiorari as improvidently granted. See Rogers v. Missouri Pacific R. Co., 352 U. S. 500, 524. As the Court itself notes, “ ‘[ejaeh'case must be decided on its peculiar, facts ....’” Such cases are unique and of no preceden-, tial value and are, therefore, outside of the criteria justifying a grant of certiorari. See Houston Oil Co. v. Goodrich, 245 U. S. 440.
