ADVANCE RULING IS NOT AN OPEN ARENA FOR EVERY CONTRACTUAL STAKEHOLDER

When Commercial Exposure Meets a Limited Statutory Remedy

The Karnataka High Court's ruling in M/s Bangalore Metro Rail Corporation Ltd. Versus Karnataka Appellate Authority For Advance Ruling, The Authority On Advance Rulings In Karnataka, The Assistant Commissioner Of Central Tax South Division – 1, Bharat Earth Movers Limited, Bangalore - 2026 (7) TMI 981 - KARNATAKA HIGH COURT addresses a question that is increasingly important in GST practice. Can a person who is not the applicant before the Authority for Advance Ruling, but who may suffer a financial impact because of the ruling, challenge that ruling in writ jurisdiction?

The answer given by the High Court is clear. A third party cannot challenge an advance ruling merely because the ruling may create a financial consequence under a private contract. The advance ruling mechanism under Chapter XVII of the CGST Act, 2017, is limited in design. It binds only the applicant who sought the ruling and the concerned or jurisdictional officer in respect of that applicant. It is not general litigation where every commercially affected person can enter the dispute.

The facts make the issue practically interesting. Bangalore Metro Rail Corporation Limited had entered into a contract with Bharat Earth Movers Limited for the supply of 150 Standard Gauge Intermediate Cars and related activities. The contract required Bangalore Metro Rail Corporation Limited to reimburse applicable GST to Bharat Earth Movers Limited as invoiced by the contractor. Bharat Earth Movers Limited approached the Authority for Advance Ruling for the classification of the supplies. The Authority for Advance Ruling, by a ruling dated 06.04.2021, reported as [In Re: M/s. Bharat Earth Movers Limited, (BEML) - 2021 (4) TMI 565 - AUTHORITY FOR ADVANCE RULING, KARNATAKA], treated the transaction as a composite supply taxable as a supply of intermediate cars. The Revenue appealed. The Karnataka Appellate Authority for Advance Ruling, by order dated 03.09.2021, reported as [In Re: M/s. BEML Limited - 2021 (9) TMI 673 - APPELLATE AUTHORITY FOR ADVANCE RULING, KARNATAKA] reclassified the supplies and held that different parts attracted GST at different rates, ranging from 5% to 28%. Bangalore Metro Rail Corporation Limited then challenged the AAAR ruling before the High Court, arguing that it would have to bear the increased GST burden under the reimbursement clause.

Section 103 Draws the Boundary

The core of the judgment lies in Section 103 of the CGST Act, 2017. That provision provides that an advance ruling pronounced by the Authority or the Appellate Authority is binding only on the applicant who sought it and on the concerned or jurisdictional officer in respect of that applicant. The language is direct and narrow. It does not say that the ruling binds customers, recipients, competitors, contractors, subcontractors, or other persons who may be commercially affected by the transaction.

The High Court has read Section 103 as the controlling provision. An advance ruling is therefore a decision in personam. It binds only the parties identified by the statute. It does not operate like a judgment in rem or a general precedent binding all persons. This distinction is extremely important. In ordinary litigation, a person who suffers adverse civil consequences may sometimes claim to be an aggrieved person. But that general idea cannot be mechanically imported into the special advance-ruling mechanism.

The Court treated Chapter XVII of the CGST Act, 2017 as a special statutory scheme. Sections 97 to 103 set out who can apply, what questions can be raised, who participates, who can appeal, and upon whom the ruling binds. This structure is not accidental. It is designed to provide certainty to the applicant and the tax authority regarding the applicant's transaction. If third parties were allowed to challenge such rulings merely because they may suffer indirect commercial consequences, the advance-ruling mechanism would lose its limited, advance-dispute-resolution character.

Financial Burden Alone Does Not Create Locus

The petitioner's strongest argument was practical. It pointed out that although Bharat Earth Movers Limited was the applicant, Bangalore Metro Rail Corporation Limited would ultimately bear the GST burden because the contract required reimbursement of applicable GST. Therefore, the ruling had a real financial impact on it.

The High Court did not ignore this argument, but it refused to treat such financial exposure as sufficient locus standi. The reason is important. The financial implication flowed from the contract between the petitioner and Bharat Earth Movers Limited, not from the statutory binding force of the advance ruling against the petitioner. Since Section 103 did not bind the petitioner, the petitioner could not claim to be an aggrieved person for challenging the ruling itself.

This is a subtle yet powerful distinction. A person may suffer commercial consequences because another party's tax position changes. But that does not automatically confer a right to challenge the ruling obtained by the other party. The remedy, if any, may lie in the contract. The third party may examine whether the reimbursement claim is payable under the contract, whether the invoice is correct, whether the supplier has acted within contractual obligations, or whether any contractual dispute exists. But the third party cannot convert a private reimbursement burden into a statutory locus to attack the advance ruling.

Applicable GST Means GST Determined by Law

The Court also examined the contract. The clauses did not fix any agreed classification of supply or any agreed rate of GST. They merely stated that Bangalore Metro Rail Corporation Limited would reimburse the GST applicable as invoiced by Bharat Earth Movers Limited. This became a decisive factual point.

The expression 'applicable GST' was treated as GST determined in accordance with law. It did not mean a rate privately understood or pre-agreed by the parties. If the contract had contained a specific classification or a fixed tax assumption that was later disturbed by the ruling, the argument of civil consequence might have looked different. But that was not the case here. The contract did not say that the supplies would be treated only in a particular manner. It only required reimbursement of GST legally applicable and invoiced by the contractor.

Therefore, the AAAR ruling did not rewrite the contract or alter an agreed tax rate between the parties. It only determined the classification in the ruling obtained by Bharat Earth Movers Limited. Since Bharat Earth Movers Limited, the applicant and supplier, had accepted the AAAR ruling, the recipient could not step in and challenge it as if it were the applicant.

Writ Jurisdiction Cannot Rewrite Commercial Terms

The petitioner sought to use Article 226 to challenge the AAAR ruling. However, entertaining such a petition would have required the High Court to treat the contract as if it contained clauses on classification and the applicable GST rate, even though those clauses were absent. The Court held that such an exercise would amount to rewriting the contract.

This part of the judgment is valuable for professionals dealing with infrastructure contracts, government contracts and long-term supply agreements. Tax clauses must be drafted with care. If parties want a particular tax classification, rate assumption, price adjustment method or dispute mechanism, the contract must state so. A general reimbursement clause may shift the financial burden, but it may not give the recipient a right to challenge every statutory determination affecting the supplier.

Writ jurisdiction is a public-law remedy. It is not meant to reconstruct private contracts. If a contractual clause provides that GST as applicable shall be reimbursed, the Court will normally read it according to its terms. It will not create a new bargain by inserting an agreed classification or rate.

Earlier Case Law Could Not Cross Section 103

The petitioner relied on several authorities, but the High Court closely considered only three decisions. In Naga Ltd., (Represented by its Authorized Signatory) General Manager Finance & Accounts Mr. S. Deepak Kumar Versus Puducherry Authority for Advance Ruling, Karaikal Port Pvt. Ltd. - 2023 (12) TMI 155 - MADRAS HIGH COURT, the Madras High Court entertained a challenge to the consequences of an advance ruling. However, the Karnataka High Court noted that Naga Ltd. did not consider the language and binding effect of Section 103. Therefore, it could not assist the petitioner in the present case.

IDL. CHEMICALS LTD. Versus UNION OF INDIA - 1996 (7) TMI 143 - Supreme Court, was also distinguished. That case dealt with the reclassification of goods under an earlier indirect tax regime. It did not concern the special GST advance-ruling scheme or the limited binding effect created by Section 103. Therefore, it could not govern the locus standi of a third party in an advance ruling matter.

The petitioner also relied on M/s. Gayatri Projects Limited & anr. Versus The Assistant Commissioner of State Tax, Durgapur Charge & Ors. - 2023 (1) TMI 333 - CALCUTTA HIGH COURT, where a third party was not left remediless. However, the Karnataka High Court found that the Calcutta High Court in that case had not examined Section 103 in detail. On the other hand, subsequent decisions such as Sarkar Diesel & Anr. Versus The Deputy Commissioner, State Tax, Krishnagar Charge & Ors. - 2024 (7) TMI 374 - CALCUTTA HIGH COURT, had recognised that an advance ruling binds only the applicant and the Department, not a third-party taxpayer.

A Strong Judicial Line on Limited Binding Force

The Court also referred to decisions supporting the limited operation of advance rulings. In M/s. Haji K.P.M. Abdul Kareem Versus Assistant Commissioner Thanjavur - 2025 (1) TMI 200 - MADRAS HIGH COURT, the Madras High Court held that an advance ruling is a decision in personam and binds only the applicant and the concerned or jurisdictional officer. In Jotun India Private Limited, Versus The Union of India through the Secretary of Finance, Department of Revenue, New Delhi, The State of Maharashtra, The Maharashtra Authority for Advance Ruling for Goods and Services Tax, Mumbai, The Maharashtra Appellate Authority for Advance Ruling for Goods and Services Tax Mumbai - 2022 (12) TMI 1135 - BOMBAY HIGH COURT, the Bombay High Court explained that the advance-ruling scheme is distinct from ordinary appeal and revision, and that its binding effect is limited by Section 103. In Mahendra Singh Versus Assistant Commissioner State Tax And Others - 2025 (9) TMI 862 - MADHYA PRADESH HIGH COURT, the Madhya Pradesh High Court held that an advance ruling rendered in the case of one person cannot be applied as binding against another person.

The underlying legal principle emerging from these decisions is simple. Advance rulings create certainty, but only for the applicant and the tax authority dealing with that applicant. They may have persuasive value for others, but they do not impose binding liability on strangers. Therefore, a third party cannot both deny being bound by the ruling and, at the same time, claim a right to challenge it as an aggrieved person.

This principle preserves the design of Chapter XVII. If every buyer, customer, competitor, subcontractor or financier could challenge an advance ruling because of possible commercial impact, the advance-ruling mechanism would become ordinary contested litigation. That is not what the statute intends.

The Practical Contracting Lesson Is Sharp

This judgment offers a clear lesson for drafting GST clauses. In large contracts, the phrase 'applicable GST shall be reimbursed' is common. However, that phrase may be insufficient if the recipient seeks control over classification disputes. Parties may need to define responsibility for classification, prior consultation, tax positions, indemnity, treatment of advance rulings, the right to contest, and the consequences of adverse rulings.

If the contract merely states that applicable GST will be reimbursed as invoiced, the recipient may find it difficult to challenge the supplier's advance ruling. The recipient may face commercial exposure but lack statutory standing in the advance-ruling proceeding. Therefore, the necessary protection must be built into the contract at the drafting stage.

The judgment is also useful for suppliers. A supplier who obtains an advance ruling is bound by it, along with the concerned officer. If the recipient is unhappy because reimbursement ends up higher, that grievance may remain contractual. It does not automatically unsettle the ruling.

Advance Ruling Certainty Has a Narrow Door

The Karnataka High Court has dismissed the writ petition for want of locus standi. The AAAR's ruling has not been interfered with. The Court held that Bangalore Metro Rail Corporation Limited, being neither the applicant nor the concerned authority, could not challenge the ruling merely because it had a reimbursement obligation under its contract with Bharat Earth Movers Limited.

The larger message is clear. Advance rulings under GST have a narrow statutory door. The applicant may enter. The concerned officer may contest. The statutory appellate mechanism may be used by the persons named in the statute. But a third party cannot enter the arena merely because the ruling may affect its commercial pocket.

For senior officers and professionals, the judgment is a timely reminder that GST law and contract law must be kept in their proper lanes. Section 103 determines the binding force of an advance ruling. The contract decides who ultimately bears the tax cost. If parties want special rights in relation to classification or tax disputes, they must write them into the contract. Otherwise, a general reimbursement clause may shift the financial burden, but it will not create statutory locus to challenge an advance ruling obtained by someone else.
