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 "natural person (excludes persons named in their official capacity or who appear because of a role in a private organization)". Your task is to determine the gender of this litigant. Use names to classify the party's sex only if there is little ambiguity (e.g., the sex of "Chris" should be coded as "not ascertained").

PER CURIAM.
The plaintiff, William J. Barbour, a seaman, brought suit against the defendant, Dravo Corporation, under the Jones Act for damages alleged to have been sustained in suffering a disabling skin disease from contact with fuel oil and oil fumes in the engine room of the vessel on which he was employed. In his complaint the plaintiff alleged unseaworthiness of the vessel and negligence on its part. The case was tried to the Court below without a jury. It found that (1) the vessel was seaworthy and (2) there was no negligence on the part of the defendant which was the proximate cause of the plaintiff’s skin disease, and accordingly, by Order, entered judgment against the plaintiff and in favor of the defendant. Our review of the record discloses that the findings of the Court below and its Order are fully supported by the evidence. For the reasons stated the Order of the Court below will be affirmed.
