Just to make sure that everyone understands how the Confirmation Period works:
Proposals that drop below 50% aye during the confirmation period are rejected right away
This is not an accurate statement – a referendum enters the Confirmation Period when it meets the Support (turnout) and Approval (ayes vs nays) criteria.
The referendum must continue to meet these parameters during the entire confirmation period.
If it does not, then it is returned to the decision period. In the case of ref 291 the decision period ended during the confirmation period - this meant that when the referendum fell below 50% approval it was instantly rejected as the decision period had ended.
