Predetermination and what councillors may say to you

A councillor is allowed to tell you they dislike a scheme. What they are not allowed to do is reach the committee with a mind closed to the officer's report and the arguments made on the day. That line between predisposition and councillor predetermination in planning decides how much your ward member can say when you knock on their door, and section 25 of the Localism Act 2011 moved it further in your favour than most residents realise.

Why councillors are cautious about committing early

Members sitting on a planning committee act in a quasi-judicial role. They decide an application against the development plan and other material considerations, and a decision reached before hearing the case can be quashed by the High Court.

That risk falls on the council, not the individual, which is why monitoring officers train members to answer lobbying carefully. The stock phrase, "I can't comment until I've seen the officer's report", is a trained response rather than an evasion.

It also explains the awkwardness residents run into. You want your councillor to say they will vote against the flats. They know that saying so in writing hands the applicant a ground of challenge if permission is refused and the decision is later tested.

Predisposition against predetermination

The distinction matters more than the vocabulary suggests.

Predisposition is a view held in advance that remains open to change. A member elected on a platform of protecting green spaces is predisposed, and that is lawful. Predetermination is a closed mind, where the member has already decided and the committee hearing is a formality.

The legal test asks whether a fair minded and informed observer, knowing the facts, would conclude there was a real possibility that the decision maker was biased. That is an objective test. It does not depend on the member's own account of their state of mind, which is why a strongly worded email matters even where the member insists they were still listening.

What the Localism Act 2011 changed

Section 25 provides that a decision maker is not to be taken to have had a closed mind just because they had previously done anything that directly or indirectly indicated what view they took, or might take, on a matter relevant to the decision.

In plain terms, campaigning, speaking at a public meeting, signing a petition or telling a local paper what they think does not automatically disqualify a councillor from voting. The section was a deliberate correction to an earlier caution that had left members afraid to represent their constituents at all.

What section 25 does not do is licence a closed mind. A member who says they will vote against an application whatever the officer's report says has gone past predisposition, and section 25 will not rescue that. Nor does it affect the rules on interests, which are separate and stricter.

Members with a disclosable interest

Interests are the area where the consequences are personal. A councillor with a disclosable pecuniary interest in a matter must declare it and must not participate in the discussion or vote, and failing to comply without reasonable excuse is a criminal offence.

Those interests cover employment, sponsorship, contracts, land and licences within the authority's area, and they extend to the interests of a spouse or partner. Councils' codes of conduct add other registrable interests and a category of non-registrable interests affecting wellbeing or financial position, where the member usually withdraws as well.

If you think a member has an undeclared interest, raise it with the monitoring officer in writing before the committee meets. Raising it afterwards is much weaker, and raising it in the public gallery achieves nothing except an adjournment.

Approaching a councillor without causing a problem

Most councils publish a lobbying protocol, and read it before you write. The approach that works:

• write to your ward member with the application reference, your address and the planning reasons for your view
• ask them to request that the application goes to committee rather than being decided by officers, which is the most useful thing a member can actually do
• accept a non-committal reply as normal rather than as a brush off
• send the same points as a formal objection through the council's website, because only that goes on the file
• avoid asking for a promise to vote a particular way, which puts the member in a difficult position and helps nobody

Ward members who are not on the committee have more freedom. They can speak at the meeting as an objector, lobby colleagues, and say what they think without restraint, because they are not deciding. If your ward member sits on the committee, ask which colleague could speak instead.

Copy in the case officer too. Our note on what to include in a parish council consultee response sets out the material that carries weight in the officer's report.

Site visits and what members may discuss

Committee site visits are for observation. Members look at the site, the relationship to neighbours, levels, trees and views, and they are accompanied by officers.

Protocols almost always prohibit taking representations during the visit. That feels unfair when you have waited outside your own house to make a point, and the reason is procedural fairness: anything said to members on site is heard by some and not others, and is not on the file for the applicant to answer. Say it at the committee meeting instead, where the applicant can respond and it is recorded.

What you can do on site is point at things. Showing members where a boundary runs or how a window faces is observation, not representation, and most officers will allow it.

Challenging a decision on bias grounds

A decision affected by predetermination can be quashed on judicial review, and the time limit for planning decisions is short, usually six weeks from the decision. You need permission from the court, and you need to show a real possibility of bias to the objective observer rather than a strong disagreement with the outcome.

Evidence that carries weight: statements committing to a particular vote before the report was published, a member acting as agent or advocate for the applicant, participation despite a declared interest, or a chair refusing to allow the committee to hear a material point.

The Local Government and Social Care Ombudsman is the other route, and it looks at maladministration in how the decision was taken rather than whether the decision was right. Neither route reopens the planning merits. If your objection is that the committee weighed the evidence differently from you, there is no remedy, because weighing the evidence is exactly what they are there to do.

That is the honest answer most residents do not want to hear. Put the effort into the objection and the committee speech, where it can change the outcome, rather than into the process afterwards.

Understanding which documents the applicant had to submit helps too. Browse the report types a planning application may include to see what should be on the file before the committee decides, and our note on when plans are amended after you object covers what happens when the scheme changes late.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
