Assessment reference amendment clarifies statutory wording to read assessments made under section 143 or section 144. Finance Act, 1963 substitutes the phrase in Section 233 of the Income-tax Act so that 'assessment made under section 143 or 144' is replaced by 'assessment made under section 143 or section 144,' effecting a textual clarification to specify the reference to section 144 in the same form as section 143.
