[Vicomte13]

Usually when the government is involved it's a bench trial, not a jury trial. Sovereigns are immune to prosecution, except to the extent they let themselves be prosecuted. Government doesn't let juries decide disputes with government.
It only allows officials of the government (judges) to arbitrate the disputes.

"It only allows officials of the government (judges) to arbitrate the disputes."

The sad fact is that the general population thinks that laws/courts/judges will somehow equal justice. It seldom does in civil cases.
