32 C.F.R. § 724.901
The objective of a discharge review is ot examine the propriety and equity of the applicant's discharge and to effect changes, if necessary. The standards of the review and the underlying factors which aid in determining whether the standards are met shall be consistent with historical criteria for determining honorable service. No factors shall be established that require automatic change or denial of a change in a discharge. Neither the NDRB nor the Secretary of the Navy shall be bound by any methodology of weighting of the factors in reaching a determination. In each case, the NDRB shall give full, fair, and impartial consideration to all applicable factors before reaching a decision. An applicant may not receive a less favorable discharge than that issued at the time of separation. This does not preclude correction of clerical errors.
