RULE 173E. Determination of normal production
-(1) Any officer duly empowered by the Commissioner in this behalf may fix the quantum and period of time when the production in the assessees factory was considered normal by such officer having regard to the installed capacity of the factory, raw material utilisation, labour employed, power consumed and such other relevant factors as he may deem appropriate. The normal quantum of production during a given time so determined by such officer shall form the norm. The assessee shall, if so required by the said officer, be called upon to explain any shortfall in production during any time, as compared to the norm. If the shortfall is not accounted for to the satisfaction of the said officer, he may assess the duty due thereon to the best of his judgment, after giving the assessee a reasonable opportunity of being heard.
(2) The officer empowered as aforesaid may revise the norm as determined by him at any time, if after such further inquiry as he may consider necessary he has reason to believe that any factor affecting the production of the factory has undergone a material change:
Provided that the norm as determined by the officer empowered as aforesaid shall not be revised to the disadvantage of the assessee unless such assessee has been given a reasonable opportunity of being heard.
