When "Pay by Phone" Doesn't Mean "Parked Legally": The Westminster Suspended Bay Case

Why This Case Matters

Picture this: you pull up, glance around for a P&D machine, tap in your location number on a parking app, pay over a tenner, and drive off feeling smug about avoiding the ticket queue. Weeks later, a Penalty Charge Notice lands on your doormat. The bay was suspended. You never saw a sign.

This scenario is far more common than most drivers realise, and it sits at the heart of a Westminster City Council case that raises an uncomfortable question: if a council's own phone payment system takes your money for a bay that's off-limits, whose fault is that really?

The adjudicator's answer offers a genuinely useful precedent for anyone who's ever paid to park without spotting a suspension notice.

The Case

The driver in question parked in a bay in Westminster, one of London's busiest and most heavily enforced boroughs for parking control. Unbeknownst to him, part of that bay had been suspended, likely for works, an event, or a contractor's booking, which is common practice across London's controlled parking zones.

He paid for his parking by phone, spending more than £10, using the location number he took from the pay and display machine nearby. He didn't spot any suspension signage. Later, he received a PCN for parking in a suspended bay or part of a bay.

He appealed, the case went to a personal hearing, and the adjudicator ultimately allowed the appeal, meaning the PCN was cancelled.

The Arguments

The driver's position was straightforward. He said he simply hadn't seen a suspension sign anywhere near where he parked. Crucially, he pointed out that he'd paid over £10 by phone, money he said he would never have handed over if he'd known the bay was suspended. Why would anyone knowingly pay to park somewhere they weren't allowed to be?

He also raised a technology argument that will resonate with a lot of drivers: surely, in an age of apps and real-time data, the phone payment system should be able to detect that a bay is suspended and refuse the payment, or at least flash up a warning. He felt the council couldn't take his money through a contractor's app and then wash its hands of responsibility when things went wrong.

Finally, he explained why he might have missed a physical sign. He believed the suspension notice, fixed to a nearby lamppost, had likely been obscured by a large van parked next to it. He also made a point about the practical reality of paying by phone: unlike walking to a machine and glancing around, phone payment involves checking a location number, entering car details, and inputting card information, all of which is far more distracting and gives you less reason to scan your surroundings for signage.

The council's position was that the phone payment system couldn't be expected to flag suspensions because a single location number often covers a whole run of bays, not all of which are necessarily suspended at any one time. In other words, the system can't distinguish between individual bays within one code. As far as Westminster was concerned, the responsibility to check physical signage remained squarely with the motorist, regardless of how they chose to pay.

The Decision

The adjudicator sided with the driver and allowed the appeal, cancelling the PCN.

Two things stood out in reaching this outcome. First, the adjudicator found the driver a credible witness, someone giving a believable, consistent account. Second, and more importantly, the adjudicator concluded that the signage in this case simply wasn't adequate.

The Legal Reasoning, Explained

This is where the case becomes genuinely instructive, because the adjudicator didn't just accept "I didn't see the sign" as a get-out-of-jail-free card. Drivers make that argument constantly, and it usually fails. What made this case different was the specific combination of circumstances.

Point one: the council took money for a bay it knew might be off-limits. The adjudicator was clearly troubled by the idea that a local authority can accept payment through a phone system, generating revenue, while knowing that part of the relevant bay is suspended, without taking meaningful steps to alert the driver at the point of payment. The reasoning wasn't that phone payment must always flag suspensions technologically. Rather, it was that if a council chooses to take payment in circumstances where suspensions exist, it has some responsibility to make sure the driver isn't misled by that transaction.

Point two: the pay and display machine itself was inside the suspended area and showed nothing. This is a crucial detail. The driver had taken his location number from a P&D machine that was physically situated within the suspended part of the bay, and that machine displayed no suspension notice whatsoever. From the driver's point of view, everything about the machine he used to pay suggested the bay was perfectly normal. The adjudicator agreed this reasonably reinforced his belief he was parked legally.

Point three: he had no reason to walk further and inspect other signage. Because his car was parked before he reached the machine, and the machine itself showed no warning, there was no obvious prompt for him to walk on and check the lamppost sign further down the street. Combined with the accepted possibility that a large van was blocking that sign from view, the adjudicator found the overall signage regime inadequate for this specific location and situation.

Put simply: adequate signage isn't just about whether a sign exists somewhere nearby. It's about whether, in the round, a reasonable motorist going about the normal process of parking and paying would actually have encountered it. Here, the layout of signage, the absence of any warning on the P&D machine, and the obstructed lamppost sign combined to fail that test.

This connects to a wider principle in parking law: local authorities carry a duty to ensure signage is clear, unambiguous, and reasonably visible to drivers. When enforcement depends on a suspension, that duty becomes even more important, because you're asking a motorist to notice an exception to what would otherwise be a perfectly normal, legal bay.

Lessons for Drivers

• Photograph everything at the time, not just the ticket. This driver's success rested heavily on being able to describe, in detail, what he saw and didn't see: the P&D machine, the van, the lamppost. If you're ever in a similar situation, take photos of the whole bay, any signage (or lack of it), obstructions, and the payment machine itself before you leave.
• Keep your payment records. The fact that he'd paid over £10 by phone was a powerful piece of evidence that he had no intention of parking illegally. Payment confirmations, timestamps, and the location number used are all worth retaining.
• Note obstructions to signage. Vans, skips, bins, or other vehicles blocking a sign aren't just bad luck, they can be genuinely relevant to whether signage was legally adequate. If something was in the way, make a note of it and, ideally, a photo.
• Don't assume phone payment tech is foolproof, but don't assume it isn't relevant either. Councils may argue their systems can't detect suspensions bay-by-bay, but as this case shows, adjudicators can still take a dim view of accepting payment in circumstances where a suspension is known to exist without adequate warning.
• Understand that "I didn't see the sign" alone rarely wins appeals. What worked here was the fuller picture: obstructed signage, a payment machine showing nothing amiss, and a logical, credible explanation for why the driver had no reason to look further. A bare assertion of not noticing a sign is unlikely to succeed on its own.

If you believe you've been wrongly issued a PCN for a suspended bay, it's worth reviewing official guidance on the appeals process and, where the financial stakes are significant, seeking independent advice before submitting your case.

Key Takeaway

Adequate signage isn't a box-ticking exercise for councils, it has to actually be visible and understandable to a reasonable driver going about their normal parking routine. If a pay and display machine within a suspended bay shows no warning, and a nearby suspension sign is obscured, don't assume you're automatically in the wrong. Sometimes the system genuinely does let drivers down, and tribunals are willing to say so.
