(d) Waiver; Withdrawal. A party waives a jury trial unless its demand is properly served and filed. A proper demand may be withdrawn only if the parties consent.
Demand: A party may demand a jury trial on any issue triable of right by a jury by serving the other parties with a written demand, which must be filed no later than 14 days after the last pleading directed to the issue. This demand must be specific about the issues that the party wants tried by a jury.
It means your ex's jury trial has been vacated (called off, whether permanently or temporarily) and the judge is meeting with your ex's attorney and the prosecutor about the case. If I had to guess, I'd say there is probably a plea agreement being discussed.
In the demand a party may specify the issues which the party wishes so tried; otherwise the party shall be deemed to have demanded trial by jury for all the issues so triable.
Prelitigation contractual waiver of the right to trial by jury is not enforceable in cases tried under the laws of Georgia. Bank S. v. Howard, 264 Ga.
If someone is accused of a crime, they have a right to be tried in front of a jury. A jury is made up of 12 people who are chosen at random to hear the evidence and decide if the accused is guilty or not guilty.
Predictable Outcomes: Judges' decisions are generally more predictable than those of a jury, in which emotions or personal biases can sway. If, for example, you're assigned a judge with a record of showing leniency for mitigating circumstances, your attorney might recommend waiving the jury trial.
Defendants generally trust that a jury will acquit or render a not guilty verdict more often (than a judge). The O.J. trial certainly validated this belief. Both the defendant and the People have the right to a jury trial in misdemeanor and felony trials (California Constitution, Article I, § 16 and Penal Code § 699).
Article I, Section 16 of the State Constitution of California says, “A trial by jury is an inviolate right and shall be secured to all. A jury may be waived in a criminal cause by the consent of both parties expressed in open court by the defendant and the defendant's counsel."
