Provincial Law

gubernator- had supreme political power over everything within the state, and governed throught the use of legates who were appointed to aid him in various ways.

Each province had a quaestor whose job it was to oversee the taxation and financials of the country.

Rule of law was drawn up in that province's lex provinciae, that defined the provinces relationship to Rome, it's laws, and, importantly, rules on taxation in the province.

Typically running for office was very expensive, and winning cushy governor positions even more so, such that any politician who had become governor had almost certainly run up significant debts; enough to tempt him to exploiting his new found authority by overtaxing his new subjects.

Provincials didn't have many ways of redress for gubernatorial abuses of power; they could take their case before provincial courts, but as these were staffed by easily corruptible Senators, true justice was likely never administered.
