United States Court of Appeals, Tenth Circuit., Olcott v. Delaware Flood Co (1989)
“ Dismissal of a properly pled federal claim does not retroactively deprive the court of subject matter jurisdiction. See Bell v. Hood, 327 U.S. 678, 682 (1946) (federal jurisdiction is not defeated by the possibility that complaint fails to state a cause of action on which a plaintiff could actually recover) . Nor does the court's dismissal of all substantive claims deprive the court of authority to enforce a previously entered sanction. A district court retains jurisdiction to impose and enforce sanctions until the court enters a final judgment. [10] See Fed. ”
