"People accused of crimes are generally brought before a judge or panel of judges, they plead their case, their accuser makes the case against them - usually both through professional proxies who know the law really well - then the judges decide whether the accused is guilty or not and what their punishment should be. People with enough political clout never get brought to trial unless their crimes are especially heinous or the evidence especially abundant because judges are corrupt and will dismiss charges out of hand if the right strings are pulled. People with enough magical power are rarely brought to trial because if they're in the habit of flouting laws any judge that finds them guilty would be afraid for their life. In Kalzir at least, magical power and political power went hand in hand, too, so there was really no way any powerful mage wound up in court. Sometimes people take justice into their own hands and murder people who got away with crimes due to political power - getting away with crimes due to magical power tends to also protect you from most would-be assassins, but occasionally other powerful people go after them and succeed. I did actually do a fair amount of that but if I can give people a fair and honest trial here I'd much rather do that.
Governments and rulers are basically never tried, especially for crimes committed during war, especially for crimes committed against foreigners, especially for crimes committed against foreigners from an enemy nation.
All in all it was a really shitty system that I don't want to replicate here. Consistent code of laws, equal application, as fair a trial as can be arranged, and if they're acquitted we respect that and leave them be. If Dwarves are pretty reasonable maybe they can be the judges, I haven't heard of any atrocities involving them so maybe they'll be unbiased."
