Task: songer_respond1_1_4

What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed respondent. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "unclear". Your task is to determine what subcategory of business best describes this litigant.

PER CURIAM.
This cause came on to be heard upon the record and briefs, and oral argument of counsel; and it appearing to the court that while no evidence of appellant’s contributory negligence was presented, and therefore the District Court erred in charging the jury upon the question (Sheen v. Kubiac, 131 Ohio St. 52, 1 N.E.2d 943; Cleveland Ry. Co. v. Heller, 15 Ohio App. 346), the error was not prejudicial, for the evidence is both substantial and persuasive to sustain a finding by the jury that the proximate cause of the accident was the sole negligence of the driver of the automobile in which appellant’ was riding as a guest passenger. It is ordered, adjudged and decreed that the judgment of the District. Court be, .and it hereby is, affirmed.
