The overarching SEBI regulation that consolidates the CONTINUING OBLIGATIONS of listed entities - periodic financial results, disclosures of material events, board composition and corporate governance - is:

The SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 ('LODR') is the master regulation unifying the continuing-compliance regime for listed entities, superseding the earlier listing agreement. It covers financial-result submission (Regulation 33), disclosure of material events (Regulation 30), board/independent-director composition (Regulations 17, 18) and a host of other governance requirements. PIT governs insider trading, SAST takeovers, and NCS non-convertible securities. As a listed Maharatna, IndianOil is squarely within LODR's compliance web.
