12. Though in the assessment order the Assessing Officer from page 1 to page 4 of his order has narrated the proceedings related to the special audit u/s. 142 (2A) of the Act and has also referred to the objection raised by the assessee to audit u/s. 142(2A) of the Act but nowhere we find that the assessee was given a sufficient opportunity to the assessee to file a reply and thereafter did not grant any opportunity of being heard. We find that the Hon’ble Delhi High Court of Punjab & Haryana in the case of Isolux Corsan India Engineering & Construction (P.) Ltd. reported in 287 CTR 92 has held “the expression the reasonable opportunity of being heard” inhers an obligation to afford a reasonable opportunity of being heard. The mere calling upon the assessee to file a reply would not fulfill the preemptory condition set out in the first proviso to Section 142(2A) of the Act. The grant of a reasonable opportunity of being heard, is a statutory pre condition to the exercise of power u/s. 42 (2A) of the Act, and if an Assessing Officer fails afford a reasonable opportunity of being heard, before passing an order u/s. 142(2A) of the Act, such an order would be null and void.
