QUESTIONS PRESENTED 1. For Petitioner to have standing to be heard on her claim that a “judgment” by a judge with an undenied appearance of undermined neutrality, must Petitioner allege and prove that Petitioner suffered harm from the “judgment”? 2. Did Petitioner have standing, in this diversity (28 U.S.C. § 1332(1)) and federal question (28 U.S.C. § 1331) action, to plead a never-before-pled claim for relief from a state court “judgment” adjudicated by a judge, with an undenied appearance of undermined neutrality? 3. Is the state court “judgment” adjudicated by a judge with an undenied appearance of undermined neutrality, named as the res in Petitioner’s in rem complaint subject to being set aside as coram non judice?
