The Commonwealth Court Case of Stalworth v. WCAB (County of Deleware) sort of falls under the topic of the Supreme Court cases discussed on Thursday. On a fatal claim that was denied, Employer's medical was possibly incompetent under Newcomer. The Commonwealth Court didn't reverse, however, because Claimant's medical was rejected by the WCJ as not credible, and it is the Claimant's burden. The Claimant failed to produce substantial, competent credible evidence to carry her burden.
