Except that the university panel system is civil in nature, not criminal.  If found to have committed sexual assault, the accused does not face prison, or any other government punishment, unless the government chooses to prosecute under the criminal system.

The panel system is like the civil trial system, which, in most, if not all, states, does not require a unanimous decision to determine culpability.  Multi-million dollar verdicts have been based on less than unanimous decisions.
