Baroness Scott of Bybrook (Con)

My Lords, I thought that everybody would be in favour of this. I begin by thanking my noble friend Lord Banner for tabling Amendment 166 and bringing this important issue before the House. The principle of proportionality deserves to stand alone in this debate, for it goes directly to the heart of the speed, efficiency and accuracy of our planning system. As ever, my noble friend has presented the case with his customary clarity and intellectual weight; I thank him for that. He has shown that this principle is not only desirable, but essential. His amendment would embed proportionality firmly within the planning process, giving decision-makers, applicants, consultees and indeed the courts confidence that less can sometimes be more. It would allow for decision-making that is sharper in focus and public participation that is clearer and more effective. I accept that this is a technically complicated clause, but it is also a vital one. At its core, it states that the information and evidence required to determine any planning application should be proportionate to the real issues at stake, taking into account decisions already made at the plan-making stage and recognising where issues could be dealt with later, whether through planning conditions, obligations or other forms of regulation. It is important to be clear about what this amendment would not do. It would not dilute or weaken the responsibility of local planning authorities to justify their decisions, particularly when refusing or withholding planning permission. Rather, it would ensure that planning does not become mired in an endless accumulation of unnecessary reports, assessments and duplications that add little value but cause delay and frustration. That is why this apparently technical definition is in fact deeply needed reform. It would be a practical safeguard against a system that too often risks becoming paralysed by its own complexity. If we are serious about unblocking progress and enabling the timely delivery of new homes—1.5 million in the next three and a half or four years—and, with them, the wider infrastructure and investment our communities require, principles such as this must be at the heart of a modern planning system. The Government would do well to accept this amendment. In doing so, they would signal that they are not just merely managing a process but are serious about reforming it, serious about tackling the barriers that hold us back and serious about delivering the homes and the growth that this country so urgently needs.
