opinion: PER CURIAM.
  This is an appeal under Title 28 U.S.C. § 1293 from a decision of the Supreme Court of Puerto Rico summarily dismissing an appeal from a judgment entered by the Superior Court of Puerto Rico, San Juan Part, for the plaintiff in an action for personal injuries arising out of an automobile accident which the plaintiff-appellee has moved to dismiss under Rule 39 of this court. The value of the amount in controversy is substantially less than $5,000 and it is abundantly clear that the federal constitutional question seasonably raised below is wholly without any substance whatever and is utterly frivolous. See Romero v. People of Puerto Rico, 1 Cir., 1950, 182 F.2d 864, 867, and cases cited, and see also Figueroa v. People of Puerto Rico, 1 Cir., 1956, 232 F.2d 615, 617, 618. The trial court issued a pretrial order and notified the parties thereof requiring them to serve each other fifteen days before the date set for trial with a list containing the documentary and oral evidence they would submit at the hearing and warned them “that in default thereof, they will be unable to introduce said evidence.” The plaintiff-appellee complied with the order; the defendant-appellant, it says by inadvertence, did not. No argument is necessary to show that the defendant-appellant was not deprived of his day in court by the trial court’s insistence that its pretrial order be obeyed. At the most all that is presented is a question of local law.
  An order will be entered dismissing the appeal for lack of jurisdiction.
instruction: 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 appellant. 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.
