(1) This regulation applies to a shot-firing permit with more than one endorsement.(2) The Secretary, by notice to the holder of a shot-firing permit, may cancel any of the endorsements if the Secretary believes on reasonable grounds that (a) the holder of the permit no longer requires that particular endorsement or can no longer demonstrate a legitimate need for it; or(b) the conditions of the permit have been contravened in a material or sustained way as regards that particular endorsement; or(c) there is other compelling justification for the cancellation.(3) However, the Secretary's power under this regulation is not capable of being exercised so as to cancel every endorsement on a shot-firing permit.(4) The cancellation of an endorsement on a shot-firing permit under this regulation takes effect when the holder of the permit is notified of it or at a later time specified in the notice.(5) The notice is to inform the holder of the permit of (a) the cancellation of the endorsement; and(b) the reasons for the cancellation; and(c) when the cancellation takes effect; and(d) the right of review.
