In Cook v. Unemployment Comp. Bd. of Review, 543 Pa. 381, 671 A.2d 1130 (1996), our Supreme Court granted an unemployment compensation appeal nunc pro tunc where the appellant filed his appeal four days late due to the fact that he had been hospitalized in intensive care following a collapse and there was no evidence that he could have conducted his appeal from his hospital bed. Cook is not a case about competency but one of impossibility where the appellant was prevented from appealing due to non-negligent circumstances beyond his control.
