there is no requirement of giving any prior notice to provide an opportunity of being heard, prior to putting a Licence/Authorisation Letter under suspension as an interim measure. On the ground that there is alleged contravention which would justify debarment from carrying on the business of selling of fertilisers or cancellation of Authorization Letter or Certificate of Registration or Certificate of Manufacture or any other Certificate granted under the Fertiliser [Control] Order, 1985., the Notified Authority or the Registering Authority, as the case may be, the Controller may, without any notice, suspend such Certificate, Authorization Letter, etc. as an interim measure, provided such authority furnishes to the affected person the details and the nature of contravention alleged to have been committed by him immediately and the authority after giving him the opportunity of being heard, is to pass final order either revoking the order of suspension or passing an order of debarment within 15 [fifteen] days from the date of issue of the order of suspension. The second proviso to sub-clause [2] of Clause 31 of the Fertiliser [Control] Order, 1985 has provided further that where no final order is passed within the period as specified above, the order of interim suspension shall be deemed to have been revoked without prejudice, however, to any further action which the authority may take against the affected person under sub-clause [1] of Clause 31 of the Fertiliser [Control] Order, 1985.
