I think the justice system of Daunton is quite disorganised to be honest (and I think that adds character to the setting), The guards answer to the mayors office, which is a separate authority to the Lords council that is comprised of the heads of the founding families (they usually meet four times a year). These two authorities seem to act independently of one another, and have different ideas of what exactly is the law of Daunton. Then there is the Politica who include a lot of the younger members of the noble families and so support the Lords Council, but have been known to side with the mayors office on occasion. All in all, it seems a bit of a mess really, which is no doubt why Brunt is often stressed!
