Twelve-Day Rule Law and Legal Definition

Twelve day rule is a principle of criminal procedure that requires a person charged with a felony to be given a preliminary examination within 12 days of his/her arraignment on the original warrant unless good cause for an adjournment is shown. This rule is applicable in some states like Michigan.

Failure to comply with the twelve-day rule entitles the defendant to be released and have the charges dismissed. [People v. McCoy, 189 Mich. App. 201, 205 (Mich. Ct. App. 1991)]
