The High Court of Delhi has dismissed a series of four appeals filed by the Commissioner of Customs , definitively ruling that Micromax Informatics Limited is entitled to statutory interest on delayed customs duty refunds. The Division Bench, comprising Justice Avneesh Jhingan and Justice Shail Jain, resolved the long-standing dispute by clarifying that once the entitlement to a principal refund is established, the payment of interest follows as a necessary legal consequence.

The proceedings, which reached the High Court under the Customs Act, 1962 , centered on the company’s import of cellular phones and mobile components between September 2014 and March 2015 . During this period, the respondent had self-assessed and paid countervailing duty (CVD) on these imports, classifying them under home consumption entries . However, the legal landscape shifted following the Supreme Court’s landmark decision in SRF Ltd. v. Commissioner of Customs , Chennai , which established that CVD was not payable on such imported goods.

Following the Supreme Court's mandate, Micromax applied for refunds of the CVD payments. While the primary refund claims were initially sanctioned, the customs authorities simultaneously ordered that the funds—along with the associated interest—be credited to the Consumer Welfare Fund (CWF) . The department argued that the respondent was not entitled to receive the money directly, citing concerns over " unjust enrichment ," a common threshold in Indian tax litigation regarding the transfer of duty burdens to end-users.

Resolving the Interest Entitlement Dispute

The current appellate matter before the High Court specifically addressed the department’s challenge to the interest component of these refunds. The Commissioner of Customs had previously contested the grant of interest, prompting a legal journey that saw the respondent succeed before the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) . The Tribunal had set aside the order of the Commissioner of Customs (Appeals) , which had initially denied the interest payments.

In its decision, the High Court emphasized that the arguments raised by the customs department were rendered moot by recent judicial developments. Specifically, the Court noted that the central issue of the principal refund amount had already been resolved in favor of Micromax by the High Court in a parallel series of cases decided on October 27, 2026 . Because the Tribunal had already directed that the principal amounts be credited to the respondent's account rather than the CWF, the argument against interest payments collapsed.

As the High Court observed in its judgment, "The natural consequence is that the statutory interest on the amount of refund due has to be paid." This stance underscores the judiciary's adherence to the principle that interest is an inherent right when a taxpayer is wrongfully deprived of their funds for an extended period, particularly when the underlying tax demand is later found to be legally infirm .

Procedural Context and Judicial Logic

The litigation involved multiple refund applications spanning several months in 2014 and 2015, with individual refund amounts totaling significant figures, such as ₹22.48 crore for the September 2014 period and over ₹68.11 crore for the November 2014 to January 2015 cycle. The Department’s refusal to pay interest on these figures was based on the premise that no refund was due in the first place, or that, if it were, it was subject to CWF deposit requirements.

During the hearing, the Tribunal’s reasoning was highlighted as a foundational element of the resolution. The Tribunal had explicitly noted: "The appellant is held entitled to payment of interest in accordance with law in respect of the first four refund applications on the principal amount that has already been sanctioned." By upholding this logic, the High Court reaffirmed that interest is not an optional add-on but a statutory requirement under the Customs Act when refunds are delayed beyond the prescribed limits.

The Court’s decision to dismiss the appeals brought by the Commissioner of Customs marks the finality of a multi-year recovery process for the respondent. The decision confirms that the statutory interest must be calculated and disbursed in accordance with the law, mirroring the relief already granted in the related matters of CUSAA 34/2024 and its connected files.

The High Court of Delhi concluded that since the validity of the refund itself was no longer in question following the previous bench’s ruling on the principal amount, there was no substantial question of law remaining that would justify further interference. By rejecting the Commissioner's petition, the Court effectively closed the door on the attempt to withhold interest on the sanctioned refund amounts.

The appeals, including those concerning the refund periods of September 2014 , October 2014, November 2014, and the early months of 2015, were dismissed in their entirety. The ruling clarifies the obligation of the state to compensate taxpayers for the time-value of money held during contested customs assessments. With these applications finalized, the respondent is expected to receive the accrued interest on the principal refunds that have already been sanctioned and cleared for disbursement.

The Court’s order, delivered on October 27, 2026 , serves as a reaffirmation of taxpayer rights against prolonged and contested refund processing. By dismissing the pending applications and confirming the Tribunal’s directive, the High Court has ensured that the operational mechanism for receiving the interest remains consistent with the established legislative framework governing customs duties in India.
