The Hon’ble Telangana High Court in M/s. BirlaNu Ltd. v. Union of India and 3 others [WRIT PETITION No. 14564 of 2024 dated December 30, 2025] struck down Rule 39(1)(a) of the Central Goods and Services Tax Rules, 2017 (“the CGST Rules”) and quashed the consequential Final Audit Report and show-cause notice, holding that the rule, to the extent it mandates distribution of Input Tax Credit by an Input Service Distributor within the same month, is ultra vires Section 20 of the Central Goods and Services Tax Act, 2017 (“the CGST Act”), as the parent act did not delegate the power to prescribe such a time limit.
Facts of the Case:
This case presents a critical examination of the boundaries of delegated legislation within the Goods and Services Tax (GST) framework. It highlights the inherent conflict that arises when a procedural rule, enacted by the executive, imposes substantive restrictions that are not contemplated by the parent statute, thereby affecting the vested rights of a taxpayer.
The pertinent facts leading to the legal challenge are as follows:
- Petitioner’s Status:M/s. BirlaNu Limited, the petitioner, is a company registered as an Input Service Distributor (ISD) under the CGST Act.
- Audit Period:The tax authorities conducted an audit of the petitioner’s records for the financial years 2017-2018 and 2018-2019.
- Action Undertaken:During the audit period, the petitioner accumulated Input Tax Credit (ITC) throughout the financial year and distributed the entire accumulated amount to its recipient units in the final month of each year (i.e., March 2018 and March 2019).
- Department’s Objection:The respondent authorities objected to this practice, contending that it violated Rule 39(1)(a) of the CGST Rules, which explicitly states that the ITC available for distribution in a particular month “shall be distributed in the same month.”
- Consequential Action:Based on this alleged contravention, the authorities issued a Final Audit Report and a subsequent show-cause notice proposing a penalty of 8,38,67,332.
Aggrieved by the authorities’ actions, which were premised on the mandatory nature of a procedural rule, the petitioner challenged the constitutional validity of the rule itself before the High Court.
Contentions of the Parties
The strategic importance of understanding the opposing legal arguments cannot be overstated, as they frame the central constitutional and statutory questions before the Court. The dispute revolved around whether a procedural rule could impose a time-based restriction on a substantive right where the parent law was silent.
Petitioner’s Contentions:
The petitioner mounted a multi-faceted challenge, arguing that the rule, the audit, and the show-cause notice were all legally unsustainable.
- Ultra Vires Nature of Rule 39(1)(a): The petitioner argued that Rule 39(1)(a) introduces a mandatory time limitation for distributing ITC, a condition not contemplated by its parent statute, Section 20 of the CGST Act. The Act only empowers the government to prescribe the “manner” of distribution, not to impose a time limit that could lead to the forfeiture of credit.
- ITC as a Vested Right:It was contended that once ITC is validly availed under the governing provisions of the Act (Sections 16 and 17), it becomes a vested and indefeasible right. A procedural rule concerning distribution cannot extinguish this substantive entitlement, especially when there was no dispute regarding the eligibility of the credit or any resulting revenue loss.
- Directory vs. Mandatory Interpretation:The petitioner submitted that the word “shall” in a procedural provision like Rule 39(1)(a) should be interpreted as directory, not mandatory. This is particularly true where non-compliance does not prejudice the revenue or defeat the core objective of the GST law, which is to prevent the cascading effect of taxes.
- Role of GSTR-6A:The argument was made that the authorities wrongly assumed that the credit “available for distribution” is determined by Form GSTR-6A. The petitioner clarified that GSTR-6A is merely a system-generated, facilitative statement and cannot be the basis for determining a statutory entitlement to ITC.
- Implication of 2024 Amendment:It was contended that the subsequent amendment to Section 20(2) by the Finance Act, 2024 (effective from April 1, 2025), which expressly grants the power to prescribe time limits, proves that no such delegated power existed during the period under dispute.
- Unjustified Invocation of Extended Limitation:The petitioner argued that the invocation of the extended period of limitation was unjustified because there was no suppression, misstatement, or fraud. All relevant details were disclosed in the returns filed on the common portal, making the information fully available to the department.
Respondents’ Contentions:
The respondents defended the validity of the rule and the legality of their actions on the grounds that they were acting within the established statutory framework.
- Intra Vires Nature of Rule 39(1)(a): The respondents countered that the rule is intra vires Section 20, as the requirement to distribute credit in the same month is an integral part of the “manner” of distribution, which the statute authorizes the government to prescribe through rules.
- Composite Statutory Scheme:It was argued that Section 20 of the Act and Rule 39 of the Rules form a single, composite scheme. The petitioner cannot selectively adhere to the Act while ignoring the binding procedural mandate of the Rule.
- Prospective Amendment:The respondents contended that the 2024 amendment to Section 20 is prospective and does not invalidate the rule for the period in question. The legality of the petitioner’s actions must be judged based on the law as it existed during the relevant financial years.
- Operationalizing the Statute:The argument was put forth that Rule 39(1)(a) lawfully operationalizes the statutory mandate of Section 20 and does not exceed the scope of delegated legislation.
- Jurisdiction:Finally, the respondents maintained that the proceedings were lawful and within their jurisdiction, and any interference by the court would prejudice the revenue.
These conflicting positions required the Court to delineate the precise scope of delegated legislative power and its impact on the substantive rights of the taxpayer.
Issues Before the Hon’ble High Court:
To systematically adjudicate the dispute, the Court distilled the parties’ elaborate arguments into five specific questions of law. These issues formed the core of the Court’s inquiry, addressing the validity of the rule, the fairness of the procedure, and the jurisdiction of the authorities.
The issues before the Hon’ble High Court:
- WhetherRule 39(1)(a) of the CGST Rules, to the extent it mandates distribution of credit within the same month, is ultra vires its parent statute, Section 20 of the CGST Act?
- Whetherthe delegated legislation in the form of Rule 39(1)(a) has exceeded the authority conferred by the parent enactment?
- Whetherthe impugned Audit Report and show-cause notice are in violation of the principles of natural justice?
- Whetherthe proceedings are barred by the normal period of limitation?
- Whetherthe existence of an alternative remedy bars the exercise of writ jurisdiction in this case?
The Court’s detailed analysis and final ruling on these fundamental questions provided much-needed clarity on the relationship between statutory provisions and subordinate rules.
Held by the Hon’ble High Court:
The Court’s decision rests on a foundational analysis of the principles of delegated legislation, the nature of vested rights, and the non-negotiable standards of procedural fairness within the GST framework. While acknowledging the need for judicial deference in matters of fiscal policy, the Court affirmed its constitutional duty to ensure that subordinate legislation does not transgress the authority granted by the parent statute.
The Hon’ble Telangana High Court in M/s. BirlaNu Ltd. v. Union of India and 3 others held as under:
- Observed that,while fiscal policy decisions invite judicial deference, judicial review is constitutionally necessary to ensure subordinate legislation remains within the bounds of the authority conferred by the parent statute.
- Noted that,Section 20 of the CGST Act, prior to its amendment, was conspicuously silent regarding any timeline for the distribution of credit, consciously confining the delegated power to the procedural mechanism (“manner”) of distribution.
- Noted that,the audit proceedings were concluded in undue haste without providing the petitioner an adequate opportunity to be heard, which is a clear derogation of the principles of natural justice and a violation of the procedural safeguards mandated by Para 5.13 of the CBIC GST Audit Manual, 2019.
- Noted that,the invocation of the extended period of limitation under Section 74 was legally untenable, as the petitioner had duly disclosed all particulars in its periodical returns, negating any allegation of “suppression” of facts.
- Held that,Rule 39(1)(a) travels beyond the scope of its parent provision, Section 20, by introducing a substantive and mandatory time limit that was not contemplated by the legislature. A rule-making authority cannot introduce a period of limitation where the parent statute does not prescribe one.
- Held that,once lawfully availed, Input Tax Credit crystallizes into a vested statutory right. An arbitrary deprivation of this right through a procedural rule that lacks express legislative sanction is a violation of Articles 14 and 300-A of the Constitution of India.
- Held that,the writ petition is maintainable as the existence of an alternative remedy does not bar writ jurisdiction when the vires of a statutory provision is challenged or there is a manifest violation of natural justice.
- Directed that,Rule 39(1)(a) of the CGST Rules, 2017, to the extent it mandates monthly distribution, is declared ultra vires Section 20 of the CGST Act, 2017, and is struck down.
- Hence,the Final Audit Report dated 22.01.2024, and the consequential show-cause notice dated 30.01.2024 are quashed and set aside.
Our Comments:
This judgment by the Hon’ble Telangana High Court is a significant ruling that reinforces the constitutional limits on delegated legislation and serves as a crucial safeguard for the substantive rights of taxpayers. It sends a clear message that procedural rules, intended to facilitate the implementation of a statute, cannot be weaponized to create substantive restrictions or extinguish vested rights that the legislature itself did not intend to curtail. The decision champions the principle that the executive’s rule-making power is subservient to the legislative intent embodied in the parent act.
At the heart of the Court’s reasoning is a robust analysis of the doctrine of delegated legislation. The Court found that Section 20 of the CGST Act, as it stood, only delegated the power to prescribe the “manner” of distributing ITC. This power is procedural in nature. However, by imposing a rigid monthly time limit, Rule 39(1)(a) introduced a substantive condition that could lead to the forfeiture of a vested right—the lawfully availed ITC. The Court correctly identified that creating such a substantive disability or obligation falls outside the purview of a general rule-making power. It reaffirmed the established legal principle that a rule cannot travel beyond the scope of its parent act and cannot be used to legislate on matters where the act itself is silent.
Supporting Jurisprudence:
The High Court’s decision was firmly anchored in established legal precedent, lending significant weight to its conclusions. The key cases relied upon include:
- Sales Tax Officer v. K. I. Abraham:This Supreme Court decision establishes the foundational principle that a rule-making authority cannot impose a time limit for claiming a right or benefit when the parent statute itself is silent on the matter. The Telangana High Court applied this principle directly to find that Rule 39(1)(a) impermissibly introduced a limitation period not sanctioned by Section 20 of the CGST Act.
- Global Energy Limited v. Central Electricity Regulatory Commission:This case was instrumental in explaining that a general delegation of power, such as the power to make rules “for carrying out the purposes of the Act,” cannot be used to create substantive disabilities or obligations that are not contemplated by the Act itself. This supported the Court’s finding that the forfeiture of ITC due to a procedural timeline was a substantive disability that the rule-making authority had no power to create.
- Pushpam Pharmaceuticals Company v. CCE:The Court cited this judgment to negate the department’s allegation of “suppression” of facts. The precedent holds that suppression cannot be alleged when the relevant facts are known to the department or are disclosed in official records. Since the petitioner had declared all ITC distribution in its returns, the invocation of the extended period of limitation was held to be legally untenable, thereby rendering the proceedings time-barred.
