Richard,

I'm very impressed with the Imperial Constitution you've developed. It seems like something that could potentially come about in the OTU if the Parliamentary Monarchists and Republicans in the Moot were to combine forces (http://wiki.travellerrpg.com/Imperial_Moot). I'm particularly pleased with Article 5, Section 13, which seems to effectively block the Imperial government from trampling around in many key areas. Strangely, however, this article seems to have two sections 3, 4 & 5. You might want to edit it a bit. A few minor concerns:

1. The interests of small-population planets seem to be treated equally to those with large populations. Or maybe I'm reading this wrong. Is the moot more like the Senate or the House? Nowhere do I see any indication that a noble's vote carries a weight proportional to the population he "governs" or the revenue he "raises", but it could be the case that I just missed it.

2. Likewise, is it possible to stack the moot by creating lots of Imperial corporations?

3. I like the fact that taxes rates are spelled out. That should hopefully prevent them from expanding into the stratosphere. However, I am somewhat concerned that they may be too low in some respects and too high in others. For example, if a noble gets to keep 1% of the money he taxes as personal wealth, that's potentially a lot of personal wealth. Ditto for the admiral who gets the keep that money. However, if the Navy is expected to operate on such a low percentage of GDP, I'm not sure it's going to be able to repel a significant threat, should one arise. Just some initial thoughts.

I'm sure I'll come up with some more comments & questions on a second reading, but in the meantime, I just wanted to say that you did great work here.
