Non-filing of Form C or filing of defective Forms C may only render the assessee liable to pay at the full rate of taxation without the benefit of concessional rate, and the filing of Forms C being optional and a mere condition to avail of the concessional rate contemplated in the statutory provision as such, the lapse, if any, cannot be considered to operate as a penal or forfeiture clause. Being an optional benefit available, non-availing of the same or non-compliance of such provision, in any event, cannot be held to be non-compliance with the provisions of the Act, Rules and Notifications- Gujarat Ambuja Cement Ltd. Vs. Assessing Authority (2000) 118 STC 315 (HP).= 1999 (8) TMI 931 - HIMACHAL PRADESH HIGH COURT
