2. a. After the filing of any complaint, the division shall promptly
serve a copy thereof upon the respondent and all persons it deems to be
necessary parties, and make prompt investigation in connection
therewith. Within one hundred eighty days after a complaint is filed,
the division shall determine whether it has jurisdiction and, if so,
whether there is probable cause to believe that the person named in the
complaint, hereinafter referred to as the respondent, has engaged or is
engaging in an unlawful discriminatory practice. If it finds with
respect to any respondent that it lacks jurisdiction or that probable
cause does not exist, the commissioner shall issue and cause to be
served on the complainant an order dismissing such allegations of the
said complaint as to such respondent.
