My understanding of Title IX is that it is a federal law that requires, among other organizations, universities, to ensure that women are not denied equal opportunities.
In order to ensure compliance with this law, universities create their own policies that they believe tackle relevant misconduct like sexual harassment, stalking, and other related behaviors. However the Title IX office of a university does not attempt to tackle behaviors that fall outside of ensuring compliance with the federal law.
Usually, faculty and staff are required to report or consult with the Title IX office if they become aware of misconduct. However, there is also a belief I have encountered that legally, academic personnel must then "back off" and completely withdraw from any conversations, actions, or other matters that relate to the issue and allow the Title IX office alone to handle it.
Is there any form of legal concern for an academic department, or faculty/staff, acting on this information further? For example, can a department chair enact sanctions on a perpetrator? Can faculty confront the perpetrator and demand their behavior cease? Can it even be discussed without legal ramifications?
Note that I am not asking about university policies on this kind of further action, but what the law and legal concerns would be. I will ask a similar question about policies on Academia Stack Exchange.
