I’m assuming that the council referred to is a town or parish council. In that case, the decision made would have been to recommend refusal. This is different from the situation in the planning authority, where the vote has immediate effect.
However most councils have standing orders that prohibit consideration of a matter already decided until six months have gone by. This can be overridden by a vote of the council, so it is possible to reconsider the decision, but only if a majority of the council is in favour of suspending the relevant standing order. This also assumes that there is time to hold another meeting before the planning authority makes a decision.
