This is an old revision of the document!
The Resolution was presented during an emergency session. It was passed unanimously within an hour. Though it is not explicitly stated that emergency sessions only need hour-long voting sessions, the hour-long period before enforcement implies that this was the intention of the founders. Therefore, the resolution is passed.
As for Sikandar's objections that Breshik is not a member, no official process was even hinted at that would prevent a nation from unilaterally joining the AN.
Therefore, the Resolution passes.
