153. When any person subject to this Ordinance has been convicted by a naval tribunal of any offence, the Government, the Chief of Naval Staff, or any officer not below the rank of captain empowered in this behalf by the Chief of Naval Staff may,(i) either without conditions or upon any conditions which the person sentenced accepts, pardon the person, or remit the whole or any part of the punishment awarded, or(ii) mitigate the punishment awarded, or commute such punishment for any less punishment or punishments mentioned in this Ordinance:Provided that a sentence of imprisonment shall not be commuted for a sentence of detention for a term exceeding the term of imprisonment awarded by the court.

154. If any condition on which a person has been pardoned or a punishment has been remitted is, in the opinion of the authority which granted the pardon or remitted the punishment, not fulfilled, such authority may cancel the pardon or remission, and thereupon the sentence shall be carried into effect as if such pardon had not been granted or such punishment had not been remitted: Provided that in the case of a person sentenced to imprisonment or detention such person shall undergo only the unexpired portion of his sentence.

155. (1) Where a person subject to this Ordinance has been sentenced by a court-martial to imprisonment or detention, the Government or the Chief of Naval Staff, or any officer empowered to convene a general or summary general court-martial may suspend the sentence whether or not the offender has already been committed to prison or custody. (2) The authority or officer specified in sub-section (1) may in the case of an offender so sentenced direct that, until the orders of such authority or officer have been obtained, the offender shall not be committed to prison or custody. (3) The powers conferred by sub-sections (1) and (2) may be exercised in the case of any such sentence which has been confirmed, mitigated or commuted.

156. A confirming officer or an officer exercising powers of summary trial may, when a person has been sentenced to imprisonment or detention, direct that the offender be not committed to prison or to custody until the orders of the authority or officer specified in section 155 have been obtained.

157. When a sentence is suspended under section 155, the offender shall, whether he has been committed to prison or to custody or not, be released forthwith.

158. Any period during which the sentence is under suspension shall be reckoned as part of the term of such sentence.

159. The authority or officer specified in section 155 may, at any time whilst a sentence is suspended, order-(a) that the offender be committed to undergo the unexpired portion of the sentence; or(b) that the sentence be remitted.

160. (1) Where a sentence has been suspended, the case may at any time, and shall, at intervals of not more than four months, be reconsidered by the authority or officer specified in section 155, or by an officer not below the rank of lieutenant Commander duly authorised by the authority or officer specified in section 155. (2) Where on such reconsideration by the officer so authorised it appears to him that the conduct of the offender since his conviction has been such as to justify a remission of the sentence, he shall refer the matter to the authority or officer specified in section 155.

161. Where an offender, while a sentence on him is suspended under this Ordinance, is sentenced for any other offence, then-(a) if the further sentence is also suspended under this Ordinance, the two sentences shall run concurrently;(b) if the further sentence is for a period of three months or more and is not suspended under this Ordinance, the offender shall also be committed to prison or naval custody for the unexpired portion of the previous sentence, but both sentences shall run concurrently; and(c) if the further sentence is for a period of less than three months and is not suspended under this Ordinance the offender shall be so committed on that sentence only, and the previous sentence shall, subject to any order which may be passed under section 159 or section 160, continue to be suspended.

162. The powers conferred by sections 155 and 159 shall be in addition to, and not in derogation of, the power of mitigation, remission and commutation.

163. (1) Where in addition to any other sentence the punishment of dismissal has been awarded by a court-martial, and such other sentence is suspended under section 155, then, such dismissal shall not take effect until so ordered by the authority or officer specified in that section. (2) If such other sentence is remitted under section 159, the punishment of dismissal shall also be remitted.
