The dean of Widener University Delaware Law School argued Wednesday that comments by attorneys representing TransPerfect co-founder Elizabeth Elting had made it impossible for rival Philip R. Shawe to prevail in the Chancery Court battle over control of the profitable translation-services company.

The argument, from Rodney Smolla, came of Shawe’s appeal of a New York judge’s decision earlier this year to dismiss Shawe’s defamation case against Elting’s Kramer Levin Naftalis & Frankel lawyers, in one of the last remaining disputes to stem from the contentious Delaware case.
