Generally speaking, courts can and do use their own “shorthand”. An educated guess?
CV Jury Trial - Long Cause; Vacated
A civil case was original set for a jury trial lasting more than 1 day. That order has been eliminated by the court.
CV Settlement Conf - Jury; Not Settled
A pre-trial discussion with the judge, designed to attempt to resolve the case without trial, was not successful.
CV Mtn to Compel Answers; Granted
There was pre-trial discovery, probably in the form of written questions. There was either no response to the questions or the responses were considered inadequate by the questioner. The questioner either asked for responses or asked for additional, supplemental responses and received none. A Motion to Compel responses was presented and granted by the court.
CV Mtn: Summary Adjudication; Taken under Submission
When the court granted the Motion to Compel, it may have granted sanctions (penalties). If so, the sanctions may have included an Order that certain facts asserted by the questioner would be treated as admitted or that certain allegations of the intended respondent be treated as rejected/denied/inadmissible or all of the foregoing. In any event, the landscape has changed, and one party has asked the court to rule in its favor in a final disposition of the case (summary judgment) or to rule in its favor on certain essential aspects of the case (summary adjudication of issues). The court is considering that request (has taken it under submission) and will make a ruling.
