so basically they are making it completely impossible for citizens to propose constitutional amendments? i didnt notice that part !
On top of year long terms for elected officials and unilateral ability to amend the constitution by the legislature with a unanimous vote.
These are probably the last regional level elections the South will have barring a massive shift.
They do have to continue holding elections, per Article VII, Section 3 of the Federal Constitution:
The Republic of Atlasia shall guarantee to every Region in this Union a republican form of government
(of course if they legally secede then who knows)
However, you are right that such elections will be pretty meaningless given their lack of frequency and the fact that SNP holds a strong plurality (almost an absolute majority) in both subregions.
