For the year 1950-51 again there was no reference and Bros. to the Bangkok branch in the return and a similar v. estimate was made for this year also. For the year Commissioner of 1951-52 also the Bangkok business profits were not Income-tax shown but on January 11, 1952, the Income-tax Bombay' Ofhcer issued a notice to the assessee under s. 22( 4) of the Act to produce the profits and loss account Sarkar J. and balance-sheet with the relevant books.
