Corellia is dominated by galaxy-spanning corporate interests that earn trillions of credits, and the planet's government has always claimed a significant share of those profits. It was only natural that the corporations would demand influence commensurate to their contributions. The world's most important business leaders formed the Corellian Corporate Council, a political policymaking coalition with representatives to every government committee.
This group's stated goal is “to ensure the smooth flow of trade between Corellia and the rest of the galaxy.” In reality, this means negotiating in back rooms to limit the government's commercial regulations and negotiate favorable tax breaks. It is no coincidence that every council chairman has been accused of fraud at least once in his career.
