“Section 135(1)”

Expenditure incurred by pharmaceutical companies on freebies provided to medical practitioners is not deductible under Explanation 1 to Section 37(1) of the Income-tax Act, as such gifting is prohibited by the Medical Council Regulations, 2002. The court also held that what is directly prohibited by law cannot be indirectly evaded through contrivance.

For computing book profits under Section 115JB, an Assessing Officer's power is limited to examining duly certified books and making adjustments only as per the Explanation. A provision for bad and doubtful debts, being a diminution in the value of an asset (receivable), does not constitute a 'provision for liability' under Clause (c) of the Explanation and therefore cannot be added back.

Weighted deduction under Section 35(2AB) is allowable for R&D expenditure incurred even if the approval from the DSIR is granted in a subsequent assessment year, provided the application for approval was made in time. The assessee is entitled to the deduction if the approval is based on verification of details submitted.

The income of a charitable trust, particularly income from property held under trust, for the purpose of claiming exemption under Section 11, must be computed in a normal commercial manner, without strict reference to the computation provisions for different heads of income like Section 14 or Section 24(a). This approach ensures that the income available for application or accumulation is assessed on commercial principles.

Expenses incurred for community development, even if not directly linked to business operations, can be considered allowable business expenditure if they foster goodwill and are part of evolving business practices.

An assessment order is not erroneous and prejudicial to the revenue merely because it does not explicitly discuss an issue for which the Assessing Officer had raised queries and the assessee had provided a response. In such a scenario, the Principal Commissioner cannot invoke revisionary powers under Section 263.

Donations made as part of Corporate Social Responsibility (CSR) expenditure are eligible for deduction under Section 80G if all conditions of Section 80G are satisfied. Such expenses are not automatically disallowed merely because they are CSR expenditure, in the absence of specific amendments to Section 80G similar to those in Section 37(1).

Section 263 cannot be invoked to revise an assessment where the Assessing Officer has made an enquiry, examined the details submitted by the assessee, and applied their mind to be satisfied about the admissibility of a claim.
