Section 4. Regional Elections.
1. No regional-administered election shall admit as eligible voters any person having resided in any other region within the fifty-six days prior to the commencement of the election.
2. In addition, no subregional senate election shall admit as eligible voters any person having resided in any other region within the fifty-six days prior to the commencement of the election.
It often helps to take a step back and consider other legislation.
The next constitution's wording doesn't really allow for a free move.
We could amend it in here, but it would just be overruled in July.
