The circumstances aren't clear from the question. Was it actually a parish meeting? That is to say, either the annual parish meeting, or a parish meeting that has been requisitioned by the appropriate number of citizens? Or was it just a meeting in the parish where all were invited to attend?
In either case, most decisions by a parish meeting are not binding on the council. The council should certainly take notice of views expressed by citizens, but is not obliged to do so (apart from a few special cases).
The planning authority is not obliged to pay any particular attention to the decisions of a parish meeting, although it is required to consult with the parish council. The response of the parish council must be decided at a council meeting to be the parish council view.
