conditions laid down in the said section and subject to such further conditions as may be laid down under the rules. First Proviso to section 13(1) of the Act provides that Input Tax Credit is available when the goods are for sale in the State or in the course of inter-State trade or commerce or in the course of export or for manufacture, processing or packing. Sub Section 5 provides for certain situations in which Input Tax Credit is not available. We are not concerned with the said situation. The said provision cannot be bar to laying down of conditions for availing input tax credit consistent with the Scheme of the Act. Thus, for claiming Input Tax Credit, there has to be liability to pay output tax. If goods which have been purchased are not available and output tax is not attracted, there could be no deduction of Input tax in respect of such goods. Provision in Rule 21 making Input Tax Credit inadmissible where goods are lost or destroyed or damaged, cannot be held to be contrary to the Scheme of the Act.
