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.

WALKER, Circuit Judge.
When this case was here on a former appeal, this court held that the trial court had erred in striking appellants’ answer to' the bill, which put in issue allegations of the bill and set up matters of set-off and counterclaim, and the case was remanded for further proceedings. Newcomb v. York Ice Machinery Corporation (C. C. A.) 56 F.(2d) 576. For a statement of the issues raised by the bill and the answer thereto reference is made to the opinion rendered when the case was here on the first appeal. Upon a consideration of the evidence adduced in the trial after the re-mandment of the cause the court found in favor of the appellee on the issues raised, and decreed accordingly. An examination of the evidence has led us to the conclusion that it duly supported the court’s findings of fact, and that none of those findings is properly subject to be set aside by this court. We think no useful purpose would be served by a recital or discussion of that evidence.
Error was assigned on the action of the court in holding that the burden was on the appellants, defendants below, to prove allegations of the answer to the bill by way of counterclaim as to the breach of the warranty, contained in the contract sued on for the sale by the appellee to the appellant Newcomb of an ice-making machine, of the ice-maldng capacity of that machine. The allegations referred to were of a matter of affirmative defense, the burden of proving which was on the appellants. Buckstaff v. Russell, 151 U. S. 626, 14 S. Ct. 448, 38 L. Ed. 292; O. C. Barber Mining & Fertilizing Co. v. Brown Hoisting Mach. Co. (C. C. A.) 258 F. 1; 24 R. C. L. 162.
The record shows no reversible error. The decree is
Affirmed.
