""the ruling figure at the subsector capitol is a high-ranking noble selected by higher levels of government. This duke has a free hand in government and is subject only to broad guidelines from his superiors. But at the same time, the duke owes fealty to the higher levels of government, ultimately to the Emperor himself. The feudal approach depends greatly on a sense of honor, one cultivated by the hereditary aristocracy. This sense of honor is very strong in the Imperium." [CT Sup 8 p 7-8]
This is a broad statement. The workings of the Imperium in 81 words. A generalization that broad is almost guaranteed to be less than accurate. There are certainly plenty of specific canonical examples that contradicts it in one way or another. Often minor ways, but contradictions nevertheless.
What I am saying, what CT clearly says, is that the Imperium is not the sort of place where everything is spelled out from a central source, the Imperium is the sort of place where the man on the spot makes his best choice within a set of broad guidelines and is then responsible for it. Therefore there cannot be an extensive set of detailed rules telling
him what to do.
No, but there can be a set of broad principles and a leavening of detailed rules for certain subjects. For example, an Imperial Code of Military Justice that applies to all Imperial forces everywhere, in and out of the Imperium. For another, a pan-Imperium ban on chattel slavery.
The Imperium has lots of laws. They just tend to be broader and more specific than ours.
Which is it, broader or more specific?
They have to be given the communications lags. If the Duke says 'Don't do that.' then his subjects cannot say 'You can't tell me that because per the Imperial Code of Justice, Section 673, Clause 4, subsection J2 I have the right to do so.'
Why not? He can then tell the subjects that the law doen't apply. They can complain to a higher authority, and if the authority agrees with them, the duke gets a rocket up his backside. Just as there was a set of very rigid instructions for the conduct of anyone in the Royal Navy from ships' boys to admirals (try googling the Articles of War and look them over). An admiral on a foreign station had broad discretionary powers, but if he broke the Articles of War, he could be hanged just as the lowliest mutinous dog of a sailor could. (Actually, since the method of execution was set by tradition rather than law, he would probably be shot instead as a concession to his social status. Byng was shot instead of hung).
What I am saying is that your interpretation seems to come from a 21st century European point of view, not from the 17th century European/American point of view that Traveller is designed to emulate.
What makes you think the 3rd Imperium was designed to emulate the 17th Century? Why not the Roman Empire? The writers drew inspiration from many sources and if the was any concious philosophy behind it, I think it would have been that similar problems produce similar solutions. Or they could have been using Toynbee's theories about the cyclical nature of history just as H. Beam Piper did (They certainly were familiar with Piper).
The 3rd Imperium is not 17th Century Britain or the Roman Empire; it just has some of the same problems. This produces a similarity between the Royal Navy and the Imperial Navy, except for all the differences, and it produces a similarity between the Imperium and the Empire except for all the differences.
Don't think of a 21st century soldier who has to worry about some set of rules directing their every action and laid down by a military and a government he can communicate with rapidly.
I don't. I think of a soldier belonging to a society that is the linear cultural heir to the Terran Confederation. And I think of adventures and amber zones that assume that the PCs' moral compass defaults to 20th Century Western values. Even when they're expected to break the law, it's often 20th Century law they're expected to break. Or they're expected to be OK with breaking the law because it's NOT 20th Century law.
Think of Captain Cook or Captain Kirk out there on the frontier weeks or years from communication making a decision for themselves. You seem to expect that the Imperium has a specific rule for everything when CT canon says that they do not.
No, I expect the Imperium to have some principles and guidelines for everything and specific rules for
some things. Which canon says they have.
