If neither tax nor fee, what is this ‘expropriation’, Supreme Court asks Govt on UPI MDR charges

This case highlights the core constitutional principle regarding the state's power to levy charges, governed by Article 265 of the Constitution, which mandates that 'no tax shall be levied or collected except by authority of law'. The Supreme Court's characterization of the MDR as a potential expropriation (the act of taking privately owned property by a government) is significant because a charge levied by the state must clearly fall into the category of a tax (compulsory extraction for public purpose without direct quid pro quo) or a fee (payment for a specific service rendered). If the MDR is neither, its legal basis becomes questionable. Furthermore, the challenge to the amended Section 10A of the Payment and Settlement Systems Act, 2007 raises the issue of delegated legislation and the limits of executive power. The petitioner argues the executive has been granted unguided discretion to determine which payment modes enjoy no-charge protection (like RuPay cards), potentially violating Article 14 (Right to Equality) if the classification is deemed arbitrary or lacking a rational nexus to the objective.

The introduction of the Merchant Discount Rate (MDR) on large UPI transactions represents a shift in India's digital payments strategy. The MDR is essentially a fee that a merchant pays to a bank for processing digital transactions. Historically, the government mandated a zero-MDR framework for UPI and RuPay to drive financial inclusion and rapid adoption of digital payments. However, payment service providers and banks have argued that maintaining this infrastructure requires significant investment, and a zero-MDR model is unsustainable. By allowing a 0.4% MDR (capped at ₹300) for transactions above ₹2,000, the National Payments Corporation of India (NPCI) aims to balance the need for widespread adoption with the commercial viability of the payment ecosystem. The debate centers on who should bear the cost of this public good—the merchant, the consumer, the banks, or the government through subsidies. UPSC aspirants must understand the implications of MDR on the digital economy, including potential impacts on merchant acceptance, consumer behavior, and the profitability of fintech companies.

The controversy surrounding the MDR on UPI transactions underscores the complexities of regulating digital public infrastructure (DPI). The National Payments Corporation of India (NPCI), which manages UPI, operates as an umbrella organization for retail payments in India. The governance challenge lies in determining the appropriate pricing model for a platform that has become essential infrastructure. The differential treatment of payment instruments—where UPI faces an MDR above a certain threshold, but RuPay debit cards retain no-charge protection without a ceiling—raises questions about regulatory neutrality. The government must ensure a level playing field among different payment service providers while simultaneously achieving public policy goals like digitization and reducing cash dependency. This scenario exemplifies the tension between fostering innovation and ensuring the sustainability of critical infrastructure, a recurring theme in modern economic governance.
