LINCOLN, Neb. (AP) — A fraternity has asked a district court judge to tell University of Nebraska-Lincoln administrators they must turn over correspondence relating to the frat’s suspension.

In March 2017 the university suspended the Phi Gamma Delta chapter for three years. Members had been accused of making vulgar comments to women during the January 2017 Women’s March in Lincoln. Administrators say an investigation uncovered what they described as reckless alcohol use, hazing and inappropriate sexually based behavior.

The Lincoln Journal Star reports that the frat filed records requests in December. The university turned over some records on May 25 but withheld nearly 1,700 others under a state provision allowing “records developed or received by law enforcement agencies and other public bodies charged with duties of investigation” to be exempted from public searches.
