This form is only for requesting a writ in a misdemeanor, infraction, or limited civil case, or a writ challenging a postjudgment enforcement order in a small claims case.
Before you fill out this form, read Information on Writ Proceedings in Misdemeanor, Infraction, and Limited Civil Cases (form APP-150-INFO) to know your rights and responsibilities.
Unless a special statute sets an earlier deadline, you should file this form no later than 30 days after the date the trial court took the action or issued the ruling you are challenging in this petition (see form APP-150-INFO, page 7, for more information about the deadline for filing a writ petition). It is your responsibility to find out if a special statute sets an earlier deadline. If your petition is filed late, the appellate division may deny it.
Fill out this form and make a copy of the completed form for your records and for the respondent (the trial court whose action or ruling you are challenging) and each of the real parties in interest (the other party or parties in the trial court case).
Serve a copy of the completed form on the respondent and on each real party in interest and keep proof of this service. Proof of Service (Appellate Division) (form APP-109) or Proof of Electronic Service (Appellate Division) (form APP-109E) can be used to make this record.
Take or mail the completed form and your proof of service on the respondent and each real party in interest to the clerk's office for the appellate division of the superior court that took the action or issued the ruling you are challenging.

a. If the trial court has not done or has refused to do something that the law says it must do, describe what you believe the law says the trial court must do, and identify the law (the section of the Constitution or statute, published court decision, or other legal authority) that says the trial court must do this.
b. If the trial court has done something that the law says the court cannot or must not do, describe what the trial court did, and identify the law that says the trial court cannot or must not do this.
c. If the trial court has performed or said it is going to perform a judicial function (like deciding a person's rights under law in a particular situation) in a way the court does not have the legal power to do, describe what the trial court did or said it is going to do. Identify the law that says the trial court does not have the power to do this.
This petition will be granted only if there is no other adequate way to address the trial court's action or ruling other than by issuing the requested writ. Explain why there is no way other than through this petition for a writ, and explain how you will be irreparably harmed if the appellate division does not issue the writ you are requesting.
