This summary is not the rule. The rule text controls.
When someone is charged with a misdemeanor in Idaho, police can use a standard form called the Idaho Uniform Citation instead of filing separate paperwork. This citation acts as both a summons (telling the person when to show up in court) and a complaint (the official charge against them).
This form is used for all misdemeanor cases, and the specific rules for how it works are found in the Misdemeanor Criminal Rules. In short, this rule just points people to where the detailed process is explained and confirms that this simpler citation method is allowed for misdemeanor charges.
