How a warning letter became somebody else’s idea

Did Fingal just tell An Bord Pleanála it didn’t know what it was doing?

In 2007 An Bord Pleanála granted planning permission for the North Runway, with conditions. One of them said which runways to use, and why: “in the interest of the protection of the amenities of the surrounding area”.

The Environmental Impact Statement behind it named the places it meant. The North Runway would be the main take-off runway, because that “minimises the over-flight of highly populated areas such as Portmarnock”. Another condition listed the schools to be soundproofed, by name. One of them is Portmarnock Community School.

So the permission knew where the planes were going. That was the point of it.

In August 2022 the runway opened, and the planes turned right after take-off, over thousands of people who had never had a flight path before. They complained to Fingal County Council, the planning authority. The law says what happens next. If a complaint isn’t “vexatious, frivolous or without substance or foundation”, the council must send a warning letter.

On 21 September 2022 Fingal sent one to daa. Its own letter, on its own letterhead, listing nine things it said might be wrong. Number three: “Aircraft flight paths are not operating in accordance with the permitted flight paths”.

Permitted flight paths. Fingal’s words. Remember them.

Four weeks later daa wrote back. The permission, it said, never granted planning permission for flight paths, “and so the reference to ‘permitted’ flight paths is inaccurate”. The routes in the EIS were only “indicative”. In the same letter daa admitted the planes were turning “closer to the Airport than anticipated by daa’s noise modelling work”. It called it “a temporary issue”.

The law says a council must decide “as expeditiously as possible”, with the “objective” of a decision “within 12 weeks of the issue of a warning letter”.

Twelve weeks. Fingal took 208.

Along the way it told the Ombudsman the file was “of a highly complex and technical nature” needing consultants, experts and specialists. It said it would “endeavour” to decide within six months. Seven weeks later it wrote to us. No six months. Just “reasonable endeavours” to decide “as expediently as possible”, and it would get back to us “in due course”.

The law says expeditiously, which means quickly. Expediently means whenever it suits.

In September 2026, as the six months ran out, Fingal’s Senior Planner signed a report. Seventeen pages of highly complex, highly technical work. No mention of a consultant, an expert or a specialist.

It starts by explaining what it’s about. “Representations allege”, it says, that flight paths are breaching the permission. Representations. Other people. Complainants.

Then it goes through the warning letter, point by point, and answers each one. On the conditions: “there is no basis for the same”. On flight paths: “the North Runway Permission does not regulate flight paths”.

Hang on. Who wrote “permitted flight paths”? Fingal did, on its own letterhead. Who decided the complaints weren’t without substance? Fingal did. That’s the legal test for sending the letter at all.

Four years on, it’s somebody else’s idea. It wasn’t us, it was the complainants. They made us write it. A clear case of BSE: Blame Somebody Else. (Story 6 has another.)

And the answer it gives them is daa’s, down to the word “indicative”.

How did it get there? Partly by noticing that the conditions don’t contain the words “flight path”. No words, no rule. So “any deviation from flight paths as assessed in the application or as previously existing does not comprise a breach of that permission”.

Any deviation. No breach.

But the conditions still protect people, says the report. They “aim to address and mitigate potential noise impacts, including through the preferential use of runways”. So you protect a town 9 km away by choosing which runway the planes take off from. And once they’re off the ground, they can go wherever they like. Which town, exactly, is that protecting?

By the report’s logic, the experts at An Bord Pleanála wrote conditions to protect the people around the runway and issued permission for the concrete and the timetable, but not for where the planes go. They got their own permission wrong. And who is saying so? Fingal, the local council, whose decisions the appeals board hears. It’s like a District Court judge ruling that the High Court didn’t understand its own judgment.

The report is careful to note the runways are used the way the conditions say, on the strength of “data and information provided by DAA”. So the conditions that protect no one are being honoured. Good to know.

In a footnote, the report mentions that Fingal is separately investigating whether the runway is being used at night when a condition says it mustn’t be. So the permission can tell planes when they may fly. It just can’t tell them where. Okay then!

The conclusion? Fingal “has established, following investigation, that no unauthorised development has been or is being carried out”. All of it, established. Except the two investigations still open, which it set aside for later.

Either way, Ireland loses, and it has been here before (story 13 has that one).

The Chief Executive’s Order adopting all this was signed on 22 September, just after the six months ran out. Two days later Fingal emailed to say the file was closed, without mentioning the Order. We got the Order and the report a week later, because we asked. Fingal’s reasonable endeavours, in due course.

So, here’s where we’ve landed. In 2022 Fingal read the permission and wrote to daa about “permitted flight paths”. daa replied that there was no such thing. Four years later Fingal agreed, and answered its own letter as if a stranger had sent it.

Either what Fingal writes in a letter means something, or it doesn’t. It hasn’t said which.
