The Sikkim High Court has quashed reassessment notices and orders issued to Zydus Healthcare for assessment years 2015-16, 2017-18 and 2018-19. Justice Bhaskar Raj Pradhan held on 14 October 2026 that an audit objection can alert the tax department to a possible issue, but it cannot by itself satisfy the statutory conditions for reopening a completed assessment beyond three years when it merely advances a different view of material already examined.
The court’s controlling distinction is concise: “The language used in section 149(1)(b) clearly contemplates new evidence and not new opinion.”

What the Sikkim High Court decided
Zydus Healthcare Limited, formerly Zydus Healthcare and later affected by its amalgamation with German Remedies, challenged reassessment action in three connected writ petitions: W.P.(C) No. 39 of 2022, W.P.(C) No. 13 of 2024 and W.P.(C) No. 50 of 2025. The matters concerned assessment years 2015-16, 2017-18 and 2018-19.

#1 Best Overall
| Assessment year | Issue identified in the proceedings | High Court result |
|---|---|---|
| 2015-16 | Excise-duty refund treated as a capital receipt; the record identifies the refund as ₹22,99,92,702 | Reassessment action quashed |
| 2017-18 | Depreciation claimed on goodwill created through amalgamation | Reassessment action quashed |
| 2018-19 | Depreciation claimed on amalgamation goodwill | Reassessment action quashed |
The proceedings followed notices under sections 148A(b), 148A(d) and 148. The dispute was not simply whether the department’s tax interpretation was correct. The threshold question was whether the Assessing Officer had lawful jurisdiction to reopen assessments that had already been completed.
Why the audit objection was insufficient
The revenue relied on audit objections concerning the excise-duty refund and depreciation on goodwill. The High Court accepted that an audit objection may constitute “information” capable of coming to the Assessing Officer’s attention for section 148 purposes. That does not, however, make reopening automatic.
The Assessing Officer must independently examine the objection and satisfy the statutory requirements. For an attempted reopening invoking the extended limitation framework in section 149(1)(b), the officer must possess books of account or other documents or evidence indicating escaped income in the manner required by the provision. A document that merely records a new conclusion about old material does not become new evidence because an audit party wrote it down.

“Merely because that opinion is written down in a document, it cannot be termed as new evidence entitling the Assessing Officer to revisit and reassess the assessment proceeding already completed.”
New evidence versus a new opinion
What the court treated as a new opinion
The objections revisited facts, documents and legal positions that were available during the original scrutiny assessments. In the goodwill dispute, depreciation had been accepted in earlier years. The later objection sought to recharacterise that position rather than identify a newly discovered document or fact that had been unavailable when the assessments were completed.
That distinction matters because a reassessment cannot be used as a second review merely because a later officer, audit team or revenue authority prefers a different interpretation of the same record. The High Court described that approach as a change of opinion.
What would make the analysis different
The ruling does not say that every audit-based reopening is invalid. A later objection could still be relevant where it points to genuinely new documentary or evidentiary material and the Assessing Officer independently explains how that material meets sections 148 and 149. The court’s objection was to using a changed view of previously examined material as though it were new evidence.
How the original assessments affected the result
The court’s reasoning turned on what had already been considered. The reassessment proposals did not uncover a separate set of books, documents or facts. They returned to the same record used in the completed scrutiny assessments and attempted to reopen the resulting conclusions.
That sequence created the jurisdictional defect:
- The original assessments had been completed after the relevant material was available to the department.
- The later audit objections proposed a different legal or accounting treatment of that material.
- The Assessing Officer treated the objections as a basis for reopening without independently identifying qualifying new evidence.
- The proposed reassessment therefore operated as a change-of-opinion review rather than a lawful reassessment founded on newly surfaced evidence.
Why the High Court heard the writ petitions
The revenue argued that Zydus should use the alternative appellate remedy available in tax proceedings instead of approaching the High Court under its writ jurisdiction. The court rejected that objection because the challenge concerned the jurisdictional preconditions for reassessment itself.
Rank #4
When the issue is whether the department had the statutory power to issue the notice, the existence of a later appeal on the merits does not necessarily prevent writ review. In this case, the court considered the alleged failure to satisfy sections 148 and 149 serious enough to examine directly and then quash the notices and orders.
What this ruling means for taxpayers facing an audit-based notice
The decision is a jurisdictional ruling on the facts before the court, not a blanket prohibition on audit objections. A taxpayer should distinguish an objection that identifies new evidence from one that simply disagrees with the original assessment.
Questions to test against the notice
- Was the issue already examined? Compare the reassessment notice with the original return, scrutiny queries, submissions and assessment order.
- What is actually new? Identify whether the notice points to a new document, book entry or other evidence, rather than only a new interpretation.
- Is the extended limitation being invoked? If the department is seeking to reopen beyond three years, check whether the notice and the Assessing Officer’s reasoning address the evidence requirements of section 149(1)(b).
- Did the Assessing Officer reason independently? An audit objection may be considered, but the officer must apply an independent mind to the assessee’s response and explain the statutory basis for proceeding.
- Is the challenge jurisdictional? A notice that fails the legal preconditions for reopening may raise a writ issue, although the appropriate remedy depends on the complete record and the applicable procedural rules.
What the judgment does—and does not—establish
The ruling establishes that an audit objection alone does not automatically confer jurisdiction to reopen a completed assessment beyond the applicable period. It also confirms that section 149(1)(b) requires new evidence, not merely a newly expressed opinion.

It does not establish that every reassessment prompted by an audit objection must fail. The outcome would require a different analysis if the objection were supported by genuinely new material and the Assessing Officer independently demonstrated that the statutory conditions were met. The judgment is therefore best read as a safeguard against using reassessment to revisit the same facts and legal position without qualifying new evidence.
The final outcome in the Zydus Healthcare cases
For Zydus Healthcare, the distinction was decisive. The excise-duty refund issue and the depreciation-on-goodwill issue were tied to material and positions already available during the original assessments. The Sikkim High Court consequently treated the attempted reopenings as impermissible changes of opinion and set aside the section 148 notices, section 148A(d) orders and all resulting reassessment proceedings for the three assessment years.
