A survey was conducted at business premises of assessee-firm and assessee filed return surrendering sum of Rs. 1 crore. Assessing Officer  held  that during survey, statements of partners were recorded and certain amount was surrendered in respect of difference in unsecured loan. He made additions with respect to surrendered amount as undisclosed income on ground that amount surrendered during survey was more than amount surrendered while filing return  Assessee contended that statement recorded during survey had no evidentiary value as same was retracted and diary found from business premises was a dumb document  Held that  additions were made solely on basis of recorded statement recorded and loose papers/diary obtained during survey without any corroborative evidence. Impounded diaries merely contained names of persons and amounts-Held that statement recorded under section 133 would not have any evidentiary value and since no enquiry was conducted by Assessing Officer from any person named in alleged diary,  additions made on account of loans and advances  are  deleted.  Held that since no unaccounted sales/purchase invoices, unaccounted lorry receipt or unaccounted party ledgers were found during survey, in absence of valid documents, additions made in regard to excess stock is deleted. Held that only source of income is  business income, undisclosed income embedded in undisclosed business transactions would not attract section 115BBE. Cash balance found from other undisclosed sources would attract section 115BBE, thus, undisclosed income attributable to excess cash would attract said section 115BBE.  (AY. 2016-17)
