What was the Domain government like?

I mean the 14th battle group was considered fine but was supplemented with the 200th legion which were war criminals at worst or disgraced at best, from mulitnes from fighting rebels, how right the rebels were are up to debate but I mean they have been maintaining martial law which is only for emergencies for like 200 years.

Also they basically robbed every domain world they found and then left them for dead.

The reason I am bringing up the 14th battle group and the hegemony is because they were the domain military (former) so that might gave us insight on the domain as a whole.
