See Wis. Stat. Sec. 36.12, Law School Rule 4.15, and Law School Rules: Appendix E. The UW's Office of Compliance publishes the current laws and policies against discrimination on their website. Current procedures for enforcement are available at the same website.
Students who have experienced or witnessed discrimination, hate, or bias should contact the Office of Student Assistance and Support and the Office of Compliance. Report bias, hate, or discrimination to the Office of Student Support and Office of Compliance.
The Assistant Dean for Student Affairs and/or the Associate Dean for Student Success & Inclusive Excellence are a great place to start should you experience discrimination, hate, or bias at the Law School. The Assistant Dean for Student Affairs can help you navigate Law School and campus resources and refer as appropriate.
