(b) During or after the investigation, but subsequent to the mailing of the notice of complaint, the City shall, if it appears that a discriminatory housing practice has occurred or is threatening to occur, attempt by informal endeavors to effect conciliation, including voluntary discontinuance of the discriminatory housing practice and adequate assurance of future voluntary compliance with the provisions of this chapter.

(c) Upon completion of the investigation and informal endeavors at conciliation by the City, but within thirty (30) days of the filing of the complaint with the City, if the efforts of the City to secure voluntary compliance have been unsuccessful, and if the City has made a determination that a discriminatory housing practice has in fact occurred, the City Attorney shall make a determination as to whether to proceed with prosecution of such complaint in municipal court. If the City Attorney determines to prosecute, he shall institute a complaint and prosecute same to conclusion within thirty (30) days after such determination, or as soon thereafter as practicable.
