The Law of Arcana
The rules of the Arcanamirium are designed for complexity merely as a puzzle for the students to figure out and for the government of the city to feel more comfortable with a large gathering of arcane talent remain self-policed. The University laws only cover disputes where both parties are members of the school.
Boiled down, the rules primarily cover murder, theft, mental intrusion, injury/forced transmutation, and collateral damage through the use of magic. Serious cases are judged by a panel of senior staff, and lesser cases by a single staff member.
Crimes against other magi are considered less important than the crimes against reality and the safety of the material plane. Unlike the other laws, crimes of this severity are clearly spelled out as they are a serious issue to magical study. The law covers unauthorized contact with the outer sphere (sometimes known as the outer planes depending on planar theory), manipulation of time, and various other dangerous acts of greater magic. Crime of this nature is covered by an external justice court known as the Varlokkur.
