Task: songer_typeiss

What follows is an opinion from a United States Court of Appeals.
Your task is to determine the general category of issues discussed in the opinion of the court. Choose among the following categories. Criminal and prisioner petitions- includes appeals of conviction, petitions for post conviction relief, habeas corpus petitions, and other prisoner petitions which challenge the validity of the conviction or the sentence or the validity of continued confinement. Civil - Government - these will include appeals from administrative agencies (e.g., OSHA,FDA), the decisions of administrative law judges, or the decisions of independent regulatory agencies (e.g., NLRB, FCC,SEC). The focus in administrative law is usually on procedural principles that apply to administrative agencies as they affect private interests, primarily through rulemaking and adjudication. Tort actions against the government, including petitions by prisoners which challenge the conditions of their confinement or which seek damages for torts committed by prion officials or by police fit in this category. In addition, this category will include suits over taxes and claims for benefits from government. Diversity of Citizenship - civil cases involving disputes between citizens of different states (remember that businesses have state citizenship). These cases will always involve the application of state or local law. If the case is centrally concerned with the application or interpretation of federal law then it is not a diversity case. Civil Disputes - Private - includes all civil cases that do not fit in any of the above categories. The opposing litigants will be individuals, businesses or groups.

PER CURIAM.
Appellants brought suit in tort against appellee in the United States District Court for the District of Arizona. Jurisdiction was founded on diversity of citizenship. In its answer appellee alleged that appellant had waived his cause of action by electing to take compensation under the Arizona Workmen’s Compensation law. See Section 23-1024(A), Arizona Revised Statutes. The trial court held a hearing limited to this defense. Appellant was the principal witness. The Court found that appellant had known that he had a cause of action against appellee and had also known that if he accepted compensation under the Workmen’s Compensation law he would lose that cause of action. The Court further found that with this knowledge appellant had applied for and received compensation from the Industrial Commission of Arizona. The Court concluded that appellant had waived his right to institute the third-party action, and ordered the complaint dismissed.
As appellant states it, on this appeal “the issue and the only issue * * * is, did the appellant know that he had a cause of action against appellee, and if he did, did he within a reasonable length of time elect to sue the third party defendant.” And, appellant continues, “the only way to determine this is to look at the evidence.” We have examined all of the evidence in the record with care, mindful of the admonition that a trial court’s findings of fact “shall not be set aside unless clearly erroneous, and due regard shall be given to the opportunity of the trial court to judge of the credibility of the witnesses.” Fed.R.Civ.P. 52(a), 28 U.S.C.A.
We are not “left with the definite and firm conviction that a mistake has been committed.” United States v. United States Gypsum Co., 333 U.S. 364, 395, 68 S.Ct. 525, 92 L.Ed. 746 (1948). Therefore, the judgment must be, and it hereby is, affirmed.
