Full Text of Rule 31.1
Plain-English Summary
Rule 31.1 is the traffic law for pretrial paperwork in a criminal case. Motions, demurrers, and special pleas have to be filed by whatever deadline the law already sets, and that deadline only moves if the judge extends it in writing before trial.
Several specific notices get their own default timeline: the state’s notice that it intends to use child victim hearsay statements, the defense’s notice that it will raise insanity, mental illness, or intellectual disability through expert or non-expert evidence, and the defense’s notice that it will introduce specific acts of violence by the victim against third persons. Each of these has to be filed at least 10 days before trial, unless the judge shortens or lengthens that window.
By pointing forward to “the following procedures,” Rule 31.1 sets the frame for the rest of Rule 31 — the later rules on hearing times, competency evaluations, insanity notices, and victim-violence evidence all build on the filing deadlines this rule establishes.
