constitutional problems
Cases the US Supreme Court reviews under its appellate jurisdiction usually involve unresolved or unclear constitutional matters that may have resulted in a Circuit split (different decisions on substantially the same question by two different US Court of Appeals Circuit Courts) or a decision from any lower appellate court that is in opposition to the Supreme Court's constitutional interpretation or to established precedents.
