Commentary First Group of Parts – Discipline Part 6 – Summary Hearing and Appeals and Review Section 133: Detention: limits on powers
284.This section places limits on the amount of detention a CO may award and the circumstances in which he may do so. A CO may award up to 28 days without extended powers and 90 days with extended powers to servicemen of the lowest non-commissioned rank. However, he must have extended powers before awarding a punishment of detention of any period to a leading rate, lance corporal, lance bombardier or corporal in the RAF (or other air force). A CO has extended powers where he has applied for them and had them granted by higher authority. COs of 2* rank have inherent extended powers.
