It is a cardinal principle of law that in order to add any income in the block assessment, evidence of such must be found in the course of the search under Section 132 of the IT Act or in any proceedings simultaneously conducted in the premises of the assessee, relatives and/or persons who are connected with the assessee and are having transaction/dealings with such assessee. In the present case, the moot question is whether the fact of cash payment of Rs 95.16 lakhs can be added under the head of the undisclosed income of the assessee in block assessment. The power of survey has been provided under Section 133A of the IT Act. Therefore, any material or evidence found/collected in a Survey which has been simultaneously made at the premises of a connected person can be utilized while making the Block Assessment in respect of an assessee under Section 158BB read with Section 158 BH of the IT Act. The same would fall under the words “and such other materials or information as are available with the Assessing Officer and relatable to such evidence” occurring in Section158 BB of the Act. In the present case, the Assessing Officer was justified in taking the adverse material collected or found during the survey or any other method while making the Block Assessment.
