One of the 13 Dalhousie University dental students suspended for their alleged involvement in a hateful Facebook group blew the whistle on the misogynistic posts, the student's lawyer says.

Ryan Millet, 29, told a female classmate she was the main target of a poll on the private Facebook group Class of DDS 2015 Gentlemen that asked who the members would most like to have "hate" sex with, according to a letter from lawyer Bruce MacIntosh provided to QMI Agency.

Millet, a father of three, also gave the woman access to his account so she could gather evidence and make a complaint to the Halifax university, MacIntosh said.

Millet is the only one of the 13 fourth-year dental students suspended from clinical activities to come forward publicly.

Last month, Millet wrote a letter of apology to his classmates that was leaked to the Chronicle Herald.

"While I did not play a direct involvement in the hurtful comments brought forth, I apologize for being a bystander," Millet wrote. "No father can stand idly by with this happening and consider himself a man. I knew it was time to step forward. My children deserve to know their father did the right thing."

MacIntosh, like many others, is critical of how the university has handled the scandal.

He says Millet has been "pilloried and secretly convicted, without due process or the right to be heard."

"At least three separate times in the last month, a dental school internal process has met behind closed doors and found him guilty of 'blatant unprofessionalism,' without once demanding a due diligence investigation or offering the opportunity to be heard," MacIntosh wrote.

The suspended students will face a disciplinary hearing Tuesday to determine if they will be permitted to graduate.

MacIntosh said the female classmate involved, identified only as AB, supports Millet's efforts to have the school's disciplinary committee expunge the suspension from his student record.

Millet requested the university make his hearing public in an attempt to set the record straight, MacIntosh said. But the request was denied.

Many have been critical of the school's decision to resolve the situation through a restorative justice process that involves the offenders meeting privately with the victims to try to reconcile.

Critics argue the university was more interested in damage control than launching an investigation into who was actually involved.

Four female dental students refused to participate amid claims the university pressured them to do so.

MacIntosh says the restorative justice process was launched prematurely.

"There was a better way, that would not have further victimized those who felt threatened, including my client as whistleblower. A prompt investigation could have led to the interim suspension of the readily identifiable offenders. Student calm could have been preserved and student safety reassured," he wrote.

"Like the Wild West, it became shoot first and ask questions later."

The school has launched an external investigation into how the dentistry faculty has handled the scandal.

Dalhousie spokesman Brian Leadbetter said the school is committed to a “just process” with its disciplinary committee.

“The process will comply with the law and university policies, and respect the rights of those involved,” he said. “Much of the work under the policies involved is confidential, to ensure that we respect the privacy of all students involved.”
