What the hell does this even mean? This makes no sense.
i) A successful vote of two thirds of voting (either in the affirmative or in the negative) members Legislative Assembly of the Northeast Region.
ii) A successful vote of majority of all members of the Legislative Assembly, voting, abstaining and absent members combined.
You wrote that there has to be a successful vote of 2/3 of the members, but then it has be a successful vote of the majority of members? What the hell?
Part (i) says that 2/3 of those who cast a ballot must cast an aye vote for the amendment to pass.
Part (ii) says that 1/2 of those who are registered voters in the Northeast must vote aye for the amendment to pass, as "absent members" seems to reference those who may vote but otherwise do not.
