Sigg: Which still leaves room for the Bailiffs and Bail Enforcement types.
IMTU, IMoJ is mostly involved in bureaucratic pursuits. They review local laws, advise nobles, provide bailiffs, magistrates, and court officers for those nobles and worlds that need them, the starport courts, as well as the sector and subsector level imperial courts, and post and pay the bounties. If a local world issues a bounty, IMoJ will hold the escrow and post the bounty IF the local IMoJ office at the starport feels it worthy.
