“Section 250(68)”

When a notice under Section 148 of the Income Tax Act is issued, the Assessing Officer is bound to furnish reasons for reopening upon the assessee's request and must dispose of the assessee's objections to the notice by passing a speaking order.

For reassessment proceedings, the 'reason to believe' that income has escaped assessment must be based on some material and not mere suspicion, establishing a live link between the information and the belief. Furthermore, for reassessment beyond four years, there must be a specific finding of the assessee's failure to disclose fully and truly all material facts.

When an issue is remitted to the Assessing Officer for fresh adjudication, the AO must conduct a de novo examination and provide the assessee a full opportunity of being heard. The assessee is bound to comply with the notices issued by the AO.

The assessee bears the onus of proving the source and nature of any sum of money or receipt found to have been received by them. If the assessee fails to satisfactorily explain the receipt, the Income-tax Officer is entitled to treat it as taxable income.

When levying a penalty under Section 271(1)(c), the Assessing Officer must clearly specify whether it is for concealment of income or furnishing inaccurate particulars. An ambiguous notice or order using "and/or" for these limbs, or a standard proforma without striking irrelevant clauses, indicates non-application of mind and renders the penalty unsustainable.

The High Court can return a reference unanswered if the assessee fails to appear or provide assistance. This illustrates the broader principle that appellate authorities have inherent power to dismiss appeals for non-prosecution when a party does not effectively pursue their case.

The exemption for long-term capital gains on share transactions is unavailable if the assessee fails to discharge the onus of proving the genuineness of gains arising from dubious share transactions designed to convert unaccounted income into tax-exempt capital gains. Courts will uphold an assessment based on the Revenue's evidence of price rigging or penny stock manipulation if the assessee cannot provide cogent evidence for the abnormal rise in share value.

Reassessment proceedings under Section 147 are invalid and void ab initio if initiated based on 'borrowed satisfaction' without the Assessing Officer's independent application of mind, or merely on documents already available on record without fresh tangible material.
