The problem I see with that is maybe not in the rare circumstance where it would happen, but if we were to put in a process whereby you were allowed to revisit an earlier vote after a period of time had elapsed, I can see again that a particular party, if they wanted to delay the voting process, which is what we're basically discussing here, could use that mechanism to revisit any number of votes.
Je sais que ce genre de choses se produira rarement, mais si on adopte une procédure qui permet de revenir sur un vote qui a déjà eu lieu, après certains délais, on peut imaginer qu'un parti, pour retarder les votes, ce dont nous parlons essentiellement ici, pourrait se servir de ce mécanisme pour revenir sur un nombre indéfini de votes.
