Story highlights A former student of Gorsuch's wrote a letter to the Senate Judiciary Committee detailing her concerns

Other students defended Gorsuch, saying conversations in the class were respectful

Washington (CNN) The University of Colorado Law School did not inform Supreme Court nominee Neil Gorsuch of a complaint filed against him last year for his conduct in a class he teaches, the law school dean said Monday.

Allegations surfaced over the weekend that Gorsuch suggested in a law class last year that women unethically use companies for maternity benefits, leading to a student to share her concerns with the law school. But the school apparently did not relay the complaint to Gorsuch.

"In late April and May 2016, law school administrators met with the student to address her concerns and told her the matter would be raised with Judge Gorsuch after grades were submitted for the spring semester," Dean S. James Anaya said in a statement. "At the end of June, the law school had a transition of deans and, regrettably, preceding that change, no member of the law school administration spoke to Judge Gorsuch about the student's concern. We apologize to the student who expressed the concern and to Judge Gorsuch for not bringing this matter to his attention last summer."

The school will not publicly discuss details of student complaints, but media reports have made it aware of the issue, Anaya wrote.

Jennifer Sisk, a former student in Gorsuch's ethics class at the law school, wrote a letter to the Senate Judiciary Committee detailing her concerns about a discussion in his course last April.
