Most determinations made by the Commission (the original determinations ) can be reconsidered and reviewed. This also applies to decisions of the Chief of the Defence Force about rehabilitation.

The Commission or the Chief of the Defence Force must give notice of an original determination to the claimant. The notice must set out the terms of and the reasons for the determination and the claimant's right to apply for review.

A claimant who has received notice of an original determination can ask the Veterans' Review Board to review it. If dissatisfied with the determination on review (the reviewable determination ), the claimant can apply to the Administrative Review Tribunal for review of the reviewable determination.

The Commission or the Chief of the Defence Force can also initiate reconsideration of original determinations made by the Commission or the Chief of the Defence Force.
