Where an employee asserts that the determination of the original claim must be revisited due to the adven — t of new evidence (i.e. evidence not previously presented), the Delegate may exercise discretion to re-examine the matter. In that case however, it is not a new claim and should be handled as a review of the original decision. It is not necessary for the e — mployee to submit a new claim form nor is it desirable to register this review as a new case.
