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.
A motion to vacate specifically asks a judge to cancel something. If a judge or jury convicted you of a crime — or you pleaded guilty — then a motion to vacate might ask the judge to cancel the conviction.
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."
For note, "Pre-Litigation Contractual Waivers of the Right to a Jury Trial Are Unenforceable Under Georgia Law," see 46 Mercer L. Rev. 1565 (1995).
(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 A proper demand may be withdrawn only if the parties consent.
I, § 1, ¶ XI. (a) The right to trial by jury shall remain inviolate, except that the court shall render judgment without the verdict of a jury in all civil cases where no issuable defense is filed and where a jury is not demanded in writing by either party.
You might be excused altogether, or your date may be deferred (rescheduled). These accepted excuses will depend on the court that called you for jury duty. You must ask to be excused. This generally involves filling out an affidavit or calling the court.
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.
