This is the best description and visualisation of ranks within the Sith Empire that I know of
Darth’s answer to no one except each other and the Dark Council up. They can kill Moff’s, Imperial Agents and Planetary Governors, however they must be wary of doing this without reasonable cause as the Dark Council may have issue with doing this which can lead to repercussions. They cannot order Moff’s or Imperial Agents without Dark Council Authority, however they can order Planetary Governors about. They are free to kill and order about any lesser Sith and Imperials for any reason. They can kill each other with impunity too. They may only kill Dark Council members and up to take their place.
Lord/Overseers/Teachers/Inquisitors/Non-titled Sith, these work roughly the same as Darth except the answer to their superior Sith ranks too. They can only kill a higher Sith rank than themselves if they intend to to take their place.
Acolytes can order and kill lesser Imperials only. They are not even allowed to kill each other without permission.
Moff is a political title (Governor of a sector of space), they have complete authority over Imperials within their space. They also have authority over “lesser than Lord” Sith in their space too. They cannot kill Sith or Imperial Agents without Dark Council authority. (Grand Moff is given to whomever is in charge of the main sector of space “the seat of power”). (As Imperials they must still show respect to all Sith, as lack of respect is a valid reason for Sith killing them)
Planetary Governors have complete authority over Imperials on their planets (most Planetary Governors tend to be Sith anyway). If they are not Sith then have no power over Sith or Imperial Agents.
Imperial Intelligence have complete authority over other Imperials, however they must be careful not to overstep their position on this as it may lead to repercussions from the Dark Council or other Sith. They cannot kill Sith or Moff’s without Dark Council authority. (As Imperials they must still show respect to all Sith, as lack of respect is a valid reason for Sith killing them)
Admirals/Generals/Ship Captains - Emergency Authority - occasionally if the situation calls for it “Lesser than Lord” Sith and Imperial Agents can be ordered about by the commanding officer of a ship/space station/ground base. However this is in completely emergency situations only (if Republic forces invaded a Imperial ship and it had Sith on-board the Captain would be allowed to command the Sith to stop the invasion).
