Revocation of registration cancellation: applicant may seek reinstatement; officer may revoke or reject after an opportunity to be heard. A registered person whose registration was cancelled by the proper officer on the officer's own motion may apply, in the prescribed manner and subject to prescribed conditions, for revocation of cancellation within the prescribed period after service of the cancellation order. The proper officer may, in the prescribed manner and period, either revoke the cancellation or reject the application, but rejection may not occur without giving the applicant an opportunity of being heard. Revocation under the Central Act is deemed a revocation under this Act.
