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 which of these categories best describes the income of the litigant. Consider the following categories: "not ascertained", "poor + wards of state" (e.g., patients at state mental hospital; not prisoner unless specific indication that poor), "presumed poor" (e.g., migrant farm worker), "presumed wealthy" (e.g., high status job - like medical doctors, executives of corporations that are national in scope, professional athletes in the NBA or NFL; upper 1/5 of income bracket), "clear indication of wealth in opinion", "other - above poverty line but not clearly wealthy" (e.g., public school teachers, federal government employees)." Note that "poor" means below the federal poverty line; e.g., welfare or food stamp recipients. There must be some specific indication in the opinion that you can point to before anyone is classified anything other than "not ascertained". Prisoners filing "pro se" were classified as poor, but litigants in civil cases who proceed pro se were not presumed to be poor. Wealth obtained from the crime at issue in a criminal case was not counted when determining the wealth of the criminal defendant (e.g., drug dealers).

The sole issue in this negligence action is whether at the jury trial the court properly received evidence of payments to the plaintiff (appellant Thompson) from an unnamed source during a period for which he claimed disability.
Plaintiff, an injured longshoreman, sought recovery from a shipowner (ap-pellee Kawasaki Kisen, K.K.) which in turn sought indemnity from the steve-doring company (Bay State), the plaintiff’s employer. The case was begun in a Massachusetts state court and removed to federal court by the shipowner on the ground of diversity. The shipowner filed a third-party complaint against the stevedoring company. The jury found for the shipowner on the claim of unseaworthiness and for the longshoreman on the claim of negligence. The third-party complaint issues were heard by the court without a jury and the stevedoring company was ordered to indemnify the shipowner. The verdict of $7,827 was for less than the payments made to the longshoreman by his employer’s compensation carrier and the court upheld the carrier’s lien.
The longshoreman is dissatisfied with the recovery and his appeal (No. 6447) is based on the alleged erroneous admission of the noted evidence. The stevedor-ing company’s appeal (No. 6457) is directed to the preservation of its third-party defendant’s rights with respect to the scope of any new trial which may be ordered.
The accident occurred when the longshoreman was working in the hold of the ship unloading cargo. He stumbled on a piece of dunnage while carrying a carton of nails. He claimed an injury to his back, was hospitalized, and asserts inability to work. On cross-examination of the plaintiff, counsel for the shipowner asked the following question:
“Q. During this period you were receiving from a source which for the moment I won’t reveal $70 a week, weren’t you ?”
An objection, which we deem appropriate to raise the issue here presented, was overruled. The answer disclosed that plaintiff had received $70 a week for an undefined period and later $52 a week, but at the time was receiving nothing.
Counsel for the longshoreman argues that the trial court erred in requiring an answer to the question on receipt of benefits during the disability period. He relies on Tipton v. Socony Mobile Oil Co., Inc., 375 U.S. 34, 84 S.Ct. 1, 11 L.Ed.2d 4, rehearing denied 375 U.S. 936, 84 S.Ct. 328, 11 L.Ed.2d 268, and Eichel v. New York Cent. R.R., 375 U.S. 253, 84 S.Ct. 316, 11 L.Ed.2d 307. Tipton is not pertinent. There the Supreme Court held that evidence of the receipt of compensation under the Longshoremen’s and Harbor Workers’ Compensation Act was not admissible on the issue of whether the plaintiff was an offshore drilling employee rather than a seaman because that status was to be determined on the basis of the facts of the case — not on the basis of a prior contention of the plaintiff.
Eichel was an action under the Federal Employers’ Liability Act and the Supreme Court held that evidence of the plaintiff’s receipt of a disability pension under the Railroad Retirement Act of 1937 was properly excluded. The Court commented that “it would violate the spirit of the federal statutes if the receipt of disability benefits under the Railroad Retirement Act * * * were considered as evidence of malingering by an employee asserting a claim under the Federal Employers’ Liability Act.”
The instant case is not based on any federal statute but rather on ordinary negligence. No authority of which we are aware holds that the rules of evidence applicable to ordinary negligence cases do not apply when the plaintiff is a longshoreman and the defendant is a shipowner. Rule 43(a), F.R.Civ.P., provides that evidence shall be admitted if it is admissible under the rules of evidence applied in either the federal courts or the courts of the state in which the federal court is held and that the rule which favors the reception of the evidence governs. The case at bar was begun in Massachusetts and removed to federal court because of diversity. Under Massachusetts law evidence of receipt of collateral income is admissible “to affect the weight of plaintiff’s previous testimony that he was disabled from working on account of the accident.” The trial court properly permitted the question to be answered.
In No. 6447 the judgment is affirmed. This action makes unnecessary the consideration of No. 6457 and that appeal is dismissed.
. Although the source of the payments was not identified, the plaintiff and his counsel, both before and after the question in issue, improperly (cf. Eichel v. New York Cent. R.R., 375 U.S. 253, 255, 84 S.Ct. 316, 11 L.Ed.2d 307) brought to the attention of the jury the presence of insurance in connection with the care and treatment which the plaintiff had received.
