Definitions in tribunal recruitment rules clarify appointing authority, tribunal roles, and reliance on the Companies Act for undefined terms. Definitions specify that ''Act'' means the Companies Act and that the ''Appointing Authority'' is the Central Government or its delegate for appointments; ''Appellate Tribunal'', ''Chairperson'' and ''Schedule'' are likewise defined. A provision states that words not defined in these rules shall have the meanings assigned to them in the Companies Act, ensuring consistency of statutory interpretation for recruitment, salary and service conditions.
