If the Board, on an application of an affected party or on its own motion, is satisfied that the entity in favour of which authorisation has been granted under section 19 has failed to comply with any conditions of authorisation, it may, after giving an opportunity to such entity of being heard, either suspend the authorisation for such period as the Board may think fit or cancel the authorisation:
Provided that where the Board is of the opinion that an authorised entity persistently acts in a manner prejudicial to the interests of consumers, it may take action for the suspension of the authorisation immediately subject to the opportunity of hearing being given subsequently, after which action so taken may be confirmed or revoked.
