Localism Bill

My noble friend remarked on new subsection (4) and the barrier against presenting any petition relating to planning matters. Knowing the strength of feeling against Gypsy sites in most localities in England, we can envisage that if people can conceivably find a way of lodging petitions against anything to do with a proposal for a Gypsy site, they will do so. I was quite relieved to hear what he said, but is it his opinion that new subsection (4) provides adequate safeguards against that kind of petition which would be unnecessary because the protection, if needed, is provided by the planning process?
