1) Are most constitutional amendments not being included in the new constitution?
Great question. In all, the current Constitution has been amended 28 times since it went into effect. Most of these amendments are minor tweaks concerning specific clauses of the current Constitution, and therefore aren't the sort of thing that would be carried over in a new document. Keep in mind that we're changing the structure of the national government quite a bit, so amendments specifying the method for... electing Class A Senators, say... aren't really relevant to the new document. That's not true of every amendment, of course; for example, the Semi-Presidentialism Amendment has been incorporated into the new Constitution. On the whole, however, we've been seeking to build a new government, not simply rearrange the old one.
2) Has the convention adopted a number of members for a political party to be recognized as official? The 18th amendment specifies the number to be three.
The new Constitution does not set any requirements that must be met in order for a party to be considered "official." The general consensus among the delegates was that the current Constitution is too pedantic, and that the new Constitution should be "a framework, not a blueprint": that is, it should prescribe only the general structure of the game and allow the people to fine-tune the system through their elected lawmakers. Election regulations - including any specifications as to what makes a party "official" - will be made by the first Congress.
3) What happens to Atlasians living in Canadian provinces? Can we still vote in Atlasian elections like citizens living abroad or the new constitution denies us the right to vote?
That's a great question - thanks for bringing this up. Because the statute reboot will not take effect until
after the scheduled elections for president and Congress, Atlasians residing in the Canadian provinces will be able to participate in that election under the terms of the Common Market Agreement. Nothing will change as far as how you vote in that first election. Under the terms of the reboot clause, all federal and regional laws - including the ACCMA - will be automatically repealed once the new government takes office. Once that happens, it will be up to the new president and Congress to reauthorize the ACCMA and amend it as necessary to reapportion the Canadian provinces between the three new Regions.
