Certificate renewal requires timely application, governmental inquiry into eligibility conditions, and permits refusal for statutory or rule violations.

Certificate renewal requires every person holding a certificate granted under section 12 to seek renewal within six months preceding its expiry. The application must be submitted in the prescribed form and manner with the prescribed fee. The Central Government may inquire into fulfilment of applicable certificate conditions, ordinarily renew within ninety days on appropriate terms, and communicate reasons where renewal is not completed within that period. Renewal may be refused for violation of governing provisions or rules.
