Not enough information here.  From what you've written, it sounds like
research misconduct, i.e., sounds like PI did not give student any
authorship.  This would be research misconduct, pure and simple.

OTOH, I don't think you've given us all the details.

Hello:   We are reviewing our publications policy and would like to know
how other institutions handle the issue of faculty and the graduate research
assistant publication rights.  In other words, how does your institution
handle a faculty member that puts his/her name on a paper a grad student
wrote then submits it for publication under their own name.

I look forward to your responses.
