Assessing Officer imposed penalty under section 271AAA of the Act.  Commissioner (Appeals) and Tribunal deleted penalty on ground that there was no specific query put to assessee to disclose manner in which undisclosed income was derived. On appeal the Court held that when  there is a statutory obligation placed upon assessee to not only specify manner in which undisclosed income had been derived but also to substantiate statement that may be made under section 132(4). On facts the  assessee merely stated that sums advanced were undisclosed income, however, she did not specify how she derived that income and what head it fell in rent, capital gain, professional or business income out of money lending, source of money, etc. Accordingly the  lower appellate authorities misdirected themselves in holding that conditions in section 271AAA(2) were satisfied. Order of Tribunal deleting the penalty is set aside.
