There are 2 ways to interpret this.
a) at least 10% of 1,384,226 = 138,422 GNO need to vote and within those there needs to be more yes than not votes
b) the yes votes need to reach this quorum AND more yes than no votes
From the text I see both interpretations possible but currently assume a) was meant. I would be though in favor of b) because otherwise a no) vote could result in the decision being made.
Imagine that yes is leading but overall the quorum has not been reached. Now - if you favour “no” it might be the better option to not vote at all. That seems like quite wired incentives and thus we should go for a) in my opinion.
