The Brumbies face potential investigation by the corporate regulator over possible breaches at the Super Rugby franchise.
ACT Policing on Wednesday confirmed it had referred the Canberra-based club to the Australian Securities and Investments Commission following an assessment by the chief police officer.
The Brumbies and Australian Rugby Union last year referred to police the sale of its Griffith headquarters and subsequent move to the University of Canberra amid concerns about some "anomalies".
Then CEO Michael Jones moved to refer documents to the police, but has since left the club amid a bitter fallout with the board that resulted in Jones launching legal action against the franchise.
Jones was stood down in March after a radio interview in which he took a swipe at "the people who are having a hack at me' telling them to back down or risk some ugly consequences/
He went to the Supreme Court for an injunction against the move to stand him down and named a number of high-profile people in the action, accusing them of pressuring the board to stand him down.
