As noted, in this case new elections are coming up soon. In future events, the suggestion to update CoI disclosure may improve governance when those are not imminent.
Even if such a measure were implemented though, this additional transparency would not be particularly actionable yet. Without means to retract one’s vote, there would remain no formal means of recourse (until new elections) in the event a future candidate were to lose voters’ trust, presuming remaining SC members were not to vote them out.
