Since closing the question about GSK’s corporate citizenship last year, the Third Circuit opened the narrower question about where the remaining cases over its antidepressant drug Paxil would be heard. That issue was before the appeals court Wednesday.

Last year, the U.S. Court of Appeals for the Third Circuit held that GlaxoSmithKline is a corporate citizen of Delaware, not Pennsylvania, which effectively preserved GSK’s ability to remove to federal court cases filed against it in Pennsylvania state courts.
