DELHI INTERNATIONAL AIRPORT LTD. vs AIRPORTS ECONOMIC REGULATORY AUTHORITY

The Supreme Court examined whether a 'new and important piece of evidence'—a 2011 internal correspondence between the Ministry of Civil Aviation and the Airport Economic Regulatory Authority—could impact the earlier judgment regarding the calculation of the Hypothetical Regulatory Asset Base (HRAB) for Delhi and Mumbai airports. The Court acknowledged that this evidence might reveal an error on the face of the record, potentially affecting the earlier decision. The case underscores the importance of accurate record analysis and the potential for new evidence to influence regulatory calculations in airport tariff disputes.
