(b) The local authority shall, not later than eight weeks after a sufficient application for a temporary state permit has been made, inform the applicant that such applicant's request for a temporary state permit has been approved or denied. The local authority shall forward a copy of the application indicating approval or denial of the temporary state permit to the Commissioner of Public Safety. If the local authority has denied the application for a temporary state permit, no state permit may be issued. The commissioner shall, not later than eight weeks after receiving an application indicating approval from the local authority, inform the applicant in writing that the applicant's application for a state permit has been approved or denied, or that the results of the national criminal history records check have not been received. If grounds for denial become known after a temporary state permit has been obtained, the temporary state permit shall be immediately revoked pursuant to section 29-32.
