In the Imperium there exists the "principle of the individual," noble but
rarely utilized, whereby a person who violates a written law in a situation of
extreme peril or need can request a special session of the court of
jurisdiction in order to explain and support the necessity of his actions. A
number of legal procedures derive from this principle, among them the Drey
Jury, the Blind Tribunal, and the Trial by Forfeiture.
