In a moral sense or a court system sense?

If accused of a Private Property law violation of the jurisdiction, you'd be tried in a court that is mutually agreed upon.
The jurisdiction will have multiple trusted courts at various levels depending on the market demands.
This is something I don't know enough about.
Imagine a combative criminal committed a violent act (allegedly), there is no agreed upon court: the criminal refuses to agree. Our current court system relies on both an appeal to God (hand on the Bible testimony) and democratic principles (laws, statues, ect.) A private court would undoubtedly be paid for by the accuser (huge bias implications) and have limited appeals to legitimacy... how can you claim an unbiased position and legitimacy in a private criminal court?
