Appellant Nehring allegedly sustained injuries on January 9, 1964, while working as a longshoreman on the S/S RIO BERMEJO, owned and operated by Appеllee Empresa Lineas Marítimas Argentinas. At the time of the alleged accident, appellant was an employee of Strachan Shipping Company, an independent contrаcting stevedoring company. Appellant brought suit against the shipowner for negligence and vessel unseaworthiness. The shipоwner subsequently impleaded the stevedore employer on the theory that, if the ship was to be cast in liability which it denied, such resulting liability stemmed from the stevedore’s breach of its warranty of wоrkmanlike service owed to the vessel in the performance of its operations.
Prior to the commencement оf the jury trial, appellant moved the trial court to equalizе the peremptory challenges, i. e. to give the appellant the same total number of peremptory challеnges that appellees were given. If not given equal challenges, appellant alternatively asked that the shipоwner’s third party action against the stevedore be severed. Appellant’s motion was denied; appellant was given thrеe peremptory challenges ; and appelleеs were each allowed *768 three challenges to be еxercised without conferring, and with no collusion between them. Thе appellant claims this was an abuse of the discretion givеn the trial court in 28 U.S.C. § 1870 (1964). There is no merit to this contention.
Following the рresentation of the evidence and arguments, the court submittеd the case to the jury upon special interrogatoriеs. The first interrogatory read: “Did the plaintiff, Lester Neh-ring, sustain an injury while working aboard the RIO BERMEJO on or about January 9, 1964?” The jury answered “no” and оbviously did not have to go further. Appellant’s second contеntion on appeal is that the trial court erred in not defining, as requested, “injury” as an aggravation of a pre-existing conditiоn, for it was this type of injury about which appellant offered proof. The argument is that the jury decided there was “no injury” without understanding what “injury” meant.
This confuses the purpose of interrogatory numbеr one, as a close reading of the record will refleсt. The theory of the defense was that there was never any accident or event or occurrence as and when аlleged by appellant: the shipowner’s trial counsel said in his оpening argument “We deny that this man sustained an accident on this ship.” (R. 18). During the trial of the ease, it was to prove or disprove thе alleged accident that most of the evidence was offered; and this question was reemphasized during closing arguments of counsel, particularly by appellees. (R. 519). Thus, the crucial issuе joined and argued in the trial below was whether or not there wаs an incident as alleged by appellant.
It was to presеnt this issue to the jury that the trial judge submitted interrogatory number one. (R. 448); and tо understand and answer it the jury needed no definition of injury. Extent or type of injury was not the inquiry. There being no need to define injury, this count finds that the jury was fairly instructed.
Affirmed.
