16Where it appears to the authority to whom a complaint to which section 16 of this Act applies is made that an act which is the subject of the complaint relates to employment and that it was done by a person acting as agent for another person but without the authorisation of that other person, the authority shall—
(a)if the Secretary of State for Employment and Productivity, refer it to the Race Relations Board ; and
(b)if not, deal with it as if it were a complaint to which section 15 of this Act applies ;
and in either event the provisions of the said section 15 shall, notwithstanding anything in section 16(1) of this Act, apply to the complaint accordingly and if the complaint was originally made to the Secretary of State or a conciliation committee shall so apply as if it had been made to the Board.
