Section 123 of ITA, 1961 : Section 123: [Omitted]

Explanation using Example

Imagine a business owner named Rahul who was filing his income tax return in 1987. At that time, he might have had to interact with an Inspecting Assistant Commissioner (IAC) for certain tax matters, as they were officials with jurisdiction in tax cases. However, after the change in the law effective from April 1, 1988, the position of IAC was eliminated. If Rahul were to file his tax return after this date, he would no longer deal with an IAC, as this role no longer existed in the tax administration framework. The responsibilities previously held by IACs would have been reassigned to other tax officials.
