Designated authority defines board officers empowered to handle defaults and noticee proceedings under intermediary regulations. Regulation 22 provides definitions for Chapter V: 'date of receipt of reply' includes oral submissions by the noticee; 'designated authority' means an officer of the Board or a bench thereof; 'noticee' is the person served a notice. It also defines 'competent authority' as a Whole Time Member or an officer not below Chief General Manager designated by the Board, and 'Executive Director' as an officer appointed by the Board, with notes recording subsequent amendments to these definitions.
