Not all of the following apply directly but they do involve respecting territorial rights, weapon sales and transportation,
I’m thinking of the Barbary Pirates who demanded tribute
The Lusitania.(sp)?, (Passenger ship sunk by the Germans who claimed it was transporting weapons)
The Patrol boats paid for by Israel, built by but not delivered by France for political reasons, (Israel sent in commandos and “Picked them up at the Factory”
The “Pueblo Incident” where an admitted spy ship was captured by North Korea because it was “Inside Territorial Waters”
Our enforcing the “Three Mile Limit” off the coast of North Africa
The mining of Vietnams harbors
Being forced to fly around the Air Space of several European nations when attacking targets in the Middle East. I have forgotten what war.
Our boarding of Frieghters and fishing trawlers in the name of “National Security”
I guess if you were to move “innocent looking” BattleCrusier size ships through my star system clearly going to my enemy, I would object.
After considering the above and the points below:

Perhaps an even stricter rule should be used.
Since no Empire should allow their rightful territory to be used to transport weapons to their enemy
Since to prevent the TF from doing so would force them to declare war on the TF
Since declaring war on the TF would be economically detrimental
The Trade Federation must respect the “Sector Space” and “Warp Point Limit” in star systems controlled by all players. To attack such a convoy would force a player to declare war on the TF. That would be realistic but not “fair” in game terms as it would weaken the player declearing war.
