What rule governs action by a commander exercising summary court-martial jurisdiction?

The rule that governs action by a commander exercising summary court-martial jurisdiction is Rule 403. This rule outlines the procedures and limitations related to the summary court-martial, which is a less formal process than a general or special court-martial and is typically used for minor offenses.

Under Rule 403, the commander has the authority to convene a summary court-martial for service members, permitting them to adjudicate minor disciplinary infractions swiftly. The rule specifies the qualifications needed for the officer presiding over the court-martial and any limitations on the types of punishments that may be imposed. This helps maintain order and discipline while also ensuring that the accused service member receives a fair and appropriate process within military justice.

Understanding this rule is crucial for anyone involved in military law or procedures, as it delineates the distinct role and authority of a commander in summary court-martial situations.
