The Assistant Secretary's determination shall be based solely on the facts concerning the alleged discriminatory housing practices provided by complainants and respondents and otherwise identified during the investigation in making this determination. In making this determination, the Assistant Secretary shall consider whether the facts concerning the alleged discriminatory housing practice are sufficient to warrant the initiation of a civil action in federal court.
