"tribunals don't care about good or evil - they are all about the law."
That seems a terribly analytical view for what is supposed to be a consistent and presumably non-computer fantasy world.
Those laws are put in place by whoever the ruling entities are, whether its the king of Taslamar or the Council of Necromancers. And those ruling bodies will have their own interests and ambitions, all of which would correlate with their alignment. The necromancers certainly don't have the citizen's best interests at heart.
If the law suddenly changed, would all the guard NPCs just keep following blindly? If they are looked at as just lines of code, then yes. But Dulrik has also said that NPCs are to be treated as living beings in a living world.
If Queen Serena was hit with a brick and decided to let necromancers prance about Exile, undead in tow, would all the paladins in the Peacekeepers just let them? Of course not. Nor would the queen ever do such a thing, because she would be influenced by her alignment.
It also ignores the fact that people use political or military office or station for personal gain all the time. An ambitious and ruthless person with no qualms about enforcing terribly unjust or downright cruel laws could easily use the Black Hand as a route to power. Would they still have to enforce the law? Well yeah. Presumably if they didn't, they'd be kicked out.
