Cancellation of registration: authorised on false statements, breaches, inactivity or public interest, with a three-year ineligibility. Cancellation is authorised where the Central Government, after inquiry, finds specified grounds: false or incorrect statements in applications, breach of certificate terms or the Act, prolonged inactivity or defunct status, or necessity in the public interest; the affected person must be given a reasonable opportunity to be heard and is ineligible for registration or prior permission for three years from cancellation.
