Where assessment had been completed under section 143(3) and, after four years, a reopening notice was issued on the ground that assessee had claimed deduction under section 80P and had failed to deduct TDS on interest paid to depositors, since there was no allegation of failure on the part of assessee to fully and truly disclose all material facts necessary for assessment and the issues relating to deduction under section 80P and disallowance for non-deduction of TDS had already been examined during original assessment proceedings, the reopening notice was held to be invalid and was quashed.
