Planning precedents and appeal decisions can significantly strengthen an objection by demonstrating that the council — or the Planning Inspectorate — has refused similar proposals on similar grounds. Understanding how to use them effectively is a skill that takes experience.
The planning system in England, Wales, Scotland and Northern Ireland is plan-led — decisions must be made against the development plan unless material considerations indicate otherwise. Unlike the legal system, planning decisions are not formally bound by precedent. However, comparable decisions carry real weight as material considerations, particularly where they demonstrate a consistent approach by the council or the Planning Inspectorate to the type of development or the specific policy arguments in question.
A planning officer who has previously recommended refusal of a similar application on similar grounds — or whose predecessor did so — will need to explain any departure from that approach. A well-cited comparable decision places the officer in a position where inconsistency requires justification.
Planning Voice uses specialist tools including LandTech and Compass to search for comparable planning decisions — both within the same local authority and from planning appeal decisions nationally. These tools allow searches by development type, policy, location, and outcome, identifying decisions that directly support the arguments being made.
Finding a refusal by the same council for a broadly similar proposal is not always straightforward — planning histories are complex, applications are rarely identical, and the policies applied may have changed. But where comparable decisions exist and are cited correctly, they materially strengthen the case.
Precedent can cut both ways. Before citing a comparable decision in an objection, it is important to check that the decision does not actually support the applicant — by, for example, demonstrating that the council routinely approves the type of development in question. Approvals are also sometimes cited by applicants in planning statements as precedents for their proposal. Identifying the distinctions between a cited approval and the case in hand is as important as finding supportive refusals.
Precedent is most powerful when combined with strong primary policy arguments. An objection that rests entirely on comparable decisions without engaging with the current Local Plan and NPPF is weaker than one where comparable decisions reinforce a clear policy-based case.
