Ombudsman definitions clarify coverage of investor complaints and intermediaries, framing scope, roles and appointment criteria. Regulation 2 defines key terms for the Ombudsman mechanism under the SEBI (Ombudsman) Regulations, 2003, specifying who may be a complainant or authorised representative, what constitutes an award, the meaning of intermediary, investor, and listed company, and the role and remuneration basis for a Stipendiary Ombudsman; undefined terms adopt meanings from the Act and subordinate instruments.
