Esteemed Klinkers and Tombeur,
In Paper 22 you propose to fix the seat of the European Congress in Brussels. I have some doubts about whether this is the right thing to do. Imagine, for example, that the Constitution is adopted by the citizens of 9 states, but not by citizens of Belgium. The Federation would then be cornered by its own Constitution to have its Congress outside of itself and a first amendment would be necessary.
Another thing which comes to mind is what happens if there is a war and Brussels is occupied by a foreign army? Why not simply give the Congress the power to decide its own seat?
