opinion: Per Curiam.
  We hold that the proofs justified with reason the jury’s conclusion that employer negligence played a part in producing the petitioner’s injury. Rogers v. Missouri Pacific R. Co., 352 U. S. 500; Webb v. Illinois Central R. Co., 352 U. S. 512; Ferguson v. Moore-McCormack Lines, 352 U. S. 521; Shaw v. Atlantic Coast Line R. Co., 353 U. S. 920; Futrelle v. Atlantic Coast Line R. Co., 353 U. S. 920; Deen v. Gulf, Colorado & Santa Fe R. Co., 353 U. S. 925; Thomson v. Texas & Pacific R. Co., 353 U. S. 926. The jury’s general verdict, that the respondent negligently contributed to the petitioner’s injury, has support in the testimony of witnesses justifying the inference that the passageway as used was not a safe place for the petitioner to work while performing his assigned duties. The special issues claimed to be in conflict with this finding concerned alleged negligence only in the operation and presence of the truck on this passageway. But even if the rule announced by the Court of Civil Appeals controlled, as we see it these answers present no square conflict. The findings on these special issues do not exhaust all of the possible grounds on which the prior unsafe-place-to-work finding of the jury may have been based. Hence all of the findings in the case might well be true insofar as the record indicates. The petitioner having asserted federal rights governed by federal law, it is our duty under the Act to make certain that they are fully protected, as the Congress intended them to be. We therefore cannot accept interpretations that nullify their effectiveness, for . . the assertion of federal rights, when plainly and reasonably made, is not to be defeated under the name of local practice.” Davis v. Wechsler, 263 U. S. 22, 24. See Dice v. Akron, Canton & Y. R. Co., 342 U. S. 359; Brown v. Western R. Co., 338 U. S. 294. The judgment of the Court of Civil Appeals is reversed and the case is remanded.
  Reversed and remanded.
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the issue area of the Court's decision. Determine the issue area on the basis of the Court's own statements as to what the case is about. Focus on the subject matter of the controversy rather than its legal basis. In specifying the issue in a legacy case, choose the one that best accords with what today's Court would consider it to be. Choose among the following issue areas: "Criminal Procedure" encompasses the rights of persons accused of crime, except for the due process rights of prisoners. "Civil rights" includes non-First Amendment freedom cases which pertain to classifications based on race (including American Indians), age, indigency, voting, residency, military or handicapped status, gender, and alienage. "First Amendment encompasses the scope of this constitutional provision, but do note that it need not involve the interpretation and application of a provision of the First Amendment. For example, if the case only construe a precedent, or the reviewability of a claim based on the First Amendment, or the scope of an administrative rule or regulation that impacts the exercise of First Amendment freedoms. "Due process" is limited to non-criminal guarantees. "Privacy" concerns libel, comity, abortion, contraceptives, right to die, and Freedom of Information Act and related federal or state statutes or regulations. "Attorneys" includes attorneys' compensation and licenses, along with trhose of governmental officials and employees. "Unions" encompass those issues involving labor union activity. "Economic activity" is largely commercial and business related; it includes tort actions and employee actions vis-a-vis employers. "Judicial power" concerns the exercise of the judiciary's own power. "Federalism" pertains to conflicts and other relationships between the federal government and the states, except for those between the federal and state courts. "Federal taxation" concerns the Internal Revenue Code and related statutes. "Private law" relates to disputes between private persons involving real and personal property, contracts, evidence, civil procedure, torts, wills and trusts, and commercial transactions. Prior to the passage of the Judges' Bill of 1925 much of the Court's cases concerned such issues. Use "Miscellaneous" for legislative veto and executive authority vis-a-vis congress or the states.
