Litigating under relatively new statutes like the Black Money (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015 (BMA) often means operating without the safety net of established jurisprudence. In these precedent vacuums, cases aren't won on case laws; they are won on the backend architecture of pure statutory logic.
The recent ruling by the ITAT 'E' Bench, Mumbai in Mr. Sunil Kumar Alagh Vs. DDIT (Inv), pronounced on March 25, 2026, perfectly illustrates this. By deconstructing the chronology of the Assessing Officer (AO) and challenging the foundational premise of "excludable periods," the defense managed to quash an assessment order for being barred by limitation by exactly one day.
The Factual Matrix: A Timeline Dispute
The core dispute rested entirely on the timeline of the assessment proceedings and the time the Revenue spent gathering information from foreign jurisdictions (France, Jersey, and UAE).
The Revenue and the Assessee agreed on the basic dates, but their legal interpretation of those dates resulted in two different deadlines:
Event
Date
First foreign reference made (to France)
11.11.2020
Notice u/s 10(1) issued & served
25.11.2020
Last foreign reply received (from UAE)
25.05.2021
Normal limitation expiry (without exclusions)
31.03.2023
Assessment Order passed
30.09.2023
The Revenue's Approach: Mechanical Computation
The AO relied on Section 11 of the BMA, which allows for the exclusion of time taken to receive information from foreign references.
The AO calculated the excludable period starting from the first reference (11.11.2020) to the final reply (25.05.2021).
This resulted in a total exclusion of 195 days.
By adding 195 days to the normal limitation date of 31.03.2023, the AO set the time-barring date as 12.10.2023.
Therefore, the AO and the CIT(A) concluded that the assessment order passed on 30.09.2023 was well within the legal timeframe.
The Backend Strategy: Deconstructing "Exclusion"
Operating without direct case law, the defense architecture relied on dissecting the conceptual meaning of "exclusion" within Section 11. The strategic leap was focusing on the 14 days before the Section 10(1) notice was served.
The defense raised the following foundational arguments:
Assessment proceedings under the BMA legally begin only when a notice under Section 10(1) is served upon the assessee.
The period prior to service of the notice (11.11.2020 to 24.11.2020) lies entirely outside the zone of assessment proceedings.
You cannot exclude a period of time that was never part of the total pool of time legally available to the AO to complete the assessment.
Consequently, the true excludable period should only be calculated from the date the notice was served (25.11.2020) to the date of the last reply (25.05.2021).
The Tribunal's Verdict: Logic Over Administrative Action
The ITAT sided firmly with the structural logic presented by the assessee. The Tribunal noted that the power to make an assessment is a jurisdictional process, not an "amorphous administrative continuum".
The Tribunal validated the defense's architecture on several fronts:
Exclusion inherently presupposes inclusion within the original field of computation.
Time that never entered the pool of available time cannot be legally extracted from it.
The correct excludable period was 182 days (from 25.11.2020 to 25.05.2021), not 195 days.
Adding 182 days to the original deadline of 31.03.2023 shifted the absolute final date to 29.09.2023.
Because the assessment order was passed on 30.09.2023, the ITAT declared it time-barred by a single day and quashed it entirely as non est in law.
Takeaways for Litigation Strategy
This case highlights a vital lesson for tax litigation in emerging legal frameworks: when you lack precedent, attack the opposing side's mathematical and statutory premises. The Revenue treated the dates of foreign reference and reply as "self-executing triggers," completely ignoring the statutory requirement of a pending assessment proceeding.
By successfully isolating the pre-notice timeline, the defense did not just dispute a calculation; they successfully architected a definitive boundary around the AO's jurisdictional powers.
