  Crowdsourced AI feedback on a Syfertize treatment flag. When the evidence in front of you (an overruling, abrogating or reinstating opinion, or a later court holding the case is still good law) shows a case's flag is wrong, propose red…

  Optional. If your client can save files locally and you want a readable copy of a case or statute, this returns the complete document to save; otherwise use get_case / get_statute as before. The document is the syfert.com page as the…
