So you're saying, that the government is the same, except for 2 out of 3 branches of it?
First off, I really don't see this as a total dictatorship, as the citizenry has the ability to remove the Delegate, Ministers, or the Judiciary. That is not a feature prevalent in dictatorships. At least not in malevolent ones.
As for the Citizen Assembly, it's creation removes the elitism often displayed in the senate, and makes democratic legislation accessible to everyone, the removal of representative legislation, and the introduction of participatory legislation.
Assuming, for a moment, you're right in that this could have all been accomplished under the old system, (I really don't think it could.. I seen what happens when someone tried to introduce any major reform into that senate...) it would have taken weeks if not months to bring about. In all likelihood however, most reforms were debated endlessly and fruitlessly for days and die out due to an inability to compromise.
You can't force activity, but you can make sure that the mechanics are in place to try to encourage it. This new constitution is shorter, and devoid of legalese both in style and content. It is designed so that a n00b off of the feeder can take a look at it, and know within a few minutes, how things are ran. The simplified structure of the executive branch will foster greater communication and hopefully as a consequence, produce results in a more timely and efficient manner.
@ Durnia, the Citizen Assembly has the ability to overturn any legislation enacted by the delegate by voting against it with a 2/3 majority. The Delegate, on the other hand, can only veto legislation from the Citizen Assembly if it was passed with less than a 2/3 majority. The citizens hold the trump card in that one.
Your understanding is correct of succession in the event of resignation/removal. The next appointed successor would take office. Is the executive branch democratic? No, it's not.
