Rule 6 party status at a planning inquiry

 

If an appeal is going to a public inquiry and you want more than the chance to stand up and speak, a Rule 6 party is the formal status that gives it to you. It makes you a main party at the inquiry, alongside the council and the person who is appealing, and it comes with real work attached. The same status can be applied for where an inquiry is being held into a called-in application rather than an appeal.

Most of the people who take it on are not individuals at all. It is usually a parish council, a residents’ association or a campaign group that has organised itself and can share the effort between several people.

This page explains what Rule 6 status gives you, what it asks of you in return, who tends to be granted it, and how the inquiry rights work in practice.

 

What a Rule 6 party is

 

The name comes from rule 6 of the rules that govern planning inquiries. Almost every appeal is decided by an inspector rather than by the Secretary of State, and those appeals run under the Town and Country Planning Appeals (Determination by Inspectors) (Inquiries Procedure) (England) Rules 2000. Where the Secretary of State takes the decision instead, a separate but similar set of rules applies.

Being granted the status makes you a main party, alongside the council and the person appealing. In practice that means three things. You receive the documents the other main parties produce, you are entitled to appear at the inquiry, and you are entitled to call your own evidence rather than simply having your say.

That last point is what really separates a Rule 6 party from an ordinary objector. An interested person can usually speak, if the inspector allows it. A Rule 6 party can put witnesses forward.

 

What you have to do in return

 

The status is not a courtesy, and it is not free of obligation. Once you are required to produce one, you must send a full statement of case within four weeks.

A statement of case is not the same thing as a letter of objection. It sets out the case you intend to put and the evidence you intend to call, and it is the document that everybody else will prepare their own case against. Writing one properly takes time, and it usually takes money.

You will also be working to the inquiry timetable rather than your own. Those deadlines run from a starting date fixed by the Planning Inspectorate, and they are set out week by week on our page about hearings and inquiries. Our guide to appeal timescales covers how long the whole process tends to take.

 

Cross-examination and Rule 6 status

 

Cross-examination means questioning another party’s witnesses directly about their evidence. Rule 6 status does not, by itself, create the same statutory right to cross-examine as the appellant, the council and statutory parties. Rule 16(5) lists the people who are entitled to cross-examine, and an ordinary Rule 6 party is not added to that list merely by receiving Rule 6 status.

In practice, Rule 6 parties are commonly allowed to question the other parties’ witnesses, and the Planning Inspectorate’s current guidance describes cross-examination as part of the role. The legal position is slightly narrower: unless the Rule 6 party is also a statutory party, questioning remains for the Inspector to allow and control. The Inspector will expect any questioning to be succinct, fair and relevant to the planning matters in dispute.

 

How you ask for Rule 6 status

 

There is no form to fill in. You write to the case officer at the Planning Inspectorate and ask.

Say who you are representing, why you want the status, and what you can bring to the inquiry that the council and the appellant will not. If you are asking on behalf of a group, set out how that group is organised: whether it is a company, whether it has a written constitution, officers, a membership list, regular meetings and an address.

The question the Inspectorate is really asking is whether you would add something substantial to the case the council or the appellant is already making. That is worth thinking about honestly before you write, because it is the ground on which these requests are refused.

 

Who is granted Rule 6 party status

 

It is unusual for one individual to be given it. The Planning Inspectorate encourages people who want the same outcome to group together and nominate a single spokesperson, and one organised group is far more likely to be accepted than several neighbours each asking separately. If you are a neighbour acting on your own, objecting to an appeal is the more realistic route.

It is worth asking whether you need it at all. If the council refused the application and is now defending its own refusal, it may already be making the points you care about, and you could get everything you want without taking on a statement of case and the cost that follows. The status earns its keep when you want to put a case that the council is not putting.

 

When Rule 6 status applies

 

Rule 6 status is an inquiry procedure. It does not apply while an appeal remains on written representations or while it is being dealt with at a hearing.

Importantly, an appeal that starts on the faster Part 1 written representations route can still be transferred to an inquiry. If that happens, the Planning Inspectorate issues an updated timetable and Rule 6 status can then be sought in the normal way. So starting in Part 1 does not prevent Rule 6 status later if the procedure changes.

Enforcement appeals and lawful development certificate appeals use separate inquiry rules and separate Planning Inspectorate guidance, so check the procedure for that appeal rather than assuming every detail on this page carries across.

 

What it costs

 

The Planning Inspectorate does not charge you for the status itself. The cost sits in the work: preparing a statement of case, preparing proofs of evidence, getting to the inquiry and being there for it, and in most cases paying somebody with experience to help you. Every party is normally expected to meet its own expenses.

For a group sharing that load between its members it is manageable. For one household it usually is not, and that is worth weighing before you ask.

There is also a risk running the other way. A Rule 6 party can apply for an award of costs against another party, and can have costs awarded against it, which ordinary interested parties are generally not exposed to. Our page on the award of costs in planning appeals explains when that happens.

Application fees are a separate matter and are set nationally rather than by your council. See our page on planning application fees.

 

If the decision goes against you

 

A Rule 6 party has no right of appeal against the inspector’s decision. Nobody except the person who made the original application has a right of appeal in England, and taking part as a main party does not change that.

What is left is a challenge in the High Court on a point of law rather than on the planning merits, and the time limit for bringing one is short. Our guides to planning appeals and to judicial review set out those routes.

• SI 2000/1624: the equivalent rules where the Secretary of State decides the appeal rather than an inspector
• SI 2009/455: amendments to the 2000 Rules, including the starting date from which the inquiry timetable runs
• SI 2013/2137: amendments to the 2000 Rules, including the removal of the separate statement of case deadline for the person appealing
