Objections to a planning application have to be based on material planning considerations and are not seen as a local referendum (at least, in theory!) If the objections raise issues that are valid - eg loss of light, loss of local visual amenity, loss of badger or bat habitat, they will then be taken into account and a balanced judgement will be made, bearing in mind that there is a presumption in favour of approval unless there would arise significant demonstrable harm to interests of acknowledged importance.
