A writ is a document or an order from a higher court that directs a lower court or a government official to take some kind of action. In any given trial, a defendant may appeal a case to the next higher appellate body only once, but the defendant may file multiple writs in that same trial. Defendants may seek several types of writs from appellate judges directed at the trial court or at a lower appellate court. Most writs require advanced legal knowledge and involve detailed procedures. Defendants contemplating making an application for a writ are wise to consult counsel.

Courts view writs as extraordinary remedies. This means that is, courts permit them only when a criminal defendant has no other adequate remedy, such as an appeal. In other words, a defendant may seek a writ to contest an issue that the defendant could not raise in a regular appeal. This action generally applies when the alleged error or mistake is not apparent in the record of the case. Generally, courts will adjudicate writs more quickly than regular appeals. If a defendant feels wronged by actions of the trial judge, he or she may need to take a writ to obtain an early review by a higher court. Some of the most common grounds for seeking a writ include:

• The defense failed to make a timely objection at the time of the alleged error or injustice
• A final judgment has not yet been entered in the trial court, but the party seeking the writ requires immediate relief to prevent further injustice or unnecessary expense
• Urgency
• The defendant has already lodged an unsuccessful appeal. Merely filing a writ that repeats the same unsuccessful grounds or arguments of an appeal is a frivolous writ and an appellate court will dismiss those writs immediately
• when an attorney has failed to investigate a possible defense
