I'm not sure such a thing falls under right to know laws, even if it is a public institution. Usually public institutions despite being "public" (and I put that in quotes because I imagine very few are 100% funded by government sources these days) have loopholes in so-called sunshine laws to get around having all of their employees' salaries made public, for example. I guess the NCAA doesn't believe in an institution's right to confront their accuser.
Except government salaries generally
are matters of public record. In fact, there are some municipalities and other governmental entities that have gone so far to include employee salaries in their respective open data, for purposes of transparency and accountability.
Side note...the public records request has to do with what the school (the public entity) is providing. As a general matter (since public records laws vary from state to state), any and all documents with a “substantial nexus” to government activities qualify as public records. For example, in Arizona, the courts have defined a "public record" as :
(1) One “made by a public officer in pursuance of a duty, the immediate purpose of which is to disseminate information to the public, or to serve as a memorial of official transactions for public reference;”
(2) A record that is “required to be kept, or necessary to be kept in the discharge of a duty imposed by law or directed by law to serve as a memorial and evidence of something written, said or done;” or
(3) Any “written record of transactions of a public officer in his office, which is a convenient and appropriate method of discharging his duties, and is kept by him as such, whether required by ... law or not.”
If a document qualifies as a public record, it is not subject to disclosure if privacy, confidentiality, or the best interests of the governmental entity outweigh the policy in favor of disclosure.
In this case, I am not sure how the complaining institution (if it is a public entity) could make arguments about privacy and confidentiality when the complaint was sent to an outside agency/third party (the AAC). While the entity can argue that identifying itself would discourage other schools from complaining in the future and would have a chilling effect on reporting misconduct, that burden would be on the school to show. And given that Tennessee submitted a complaint about UConn years ago (and was identified as the complaining institution), that did not stop another school (in this case) from submitting a complaint. That would defeat the "chilling effect" argument.
Just some food for thought regarding governmental entities and public institutions, public records, and public records requests.
