The issue regarding ticketing as it stands, is that it comes under contract law. The contract is between the driver of the vehicle and the parking company.
However, the details obtained from DVLA are for the registered keeper - not the driver. There's no legal requirement for a registered keeper to supply driver details. So in effect if they deny the offense, which they will, the chances of the ticket standing up in court is very little which is why companys don't bother taking it that far. They send out a few letter from debt collection firms - usually part of the same company, if they don't get any joy it gets written off.
I've met quite a few of the owners of the larger PPC's and they're all saying the same thing, if the owner doesn't pay, they won't follow it up to court.
However, having said that, there are moves to introduce legislation to make the registered keeper liable in the same way that they are for a council issued ticket. It's the pay off for scrapping clamping.
What will happen is that if an owner feels the ticket is invalid, then the PPC can take it to court where they will have to produce sufficient evidence to prove the offence. Long winded, but if they do it by the book there shouldn't be a problem.
It's all about balance at the end of the day, landholders should have a right to protect their property - and that shouldn't mean spending thousands on barriers, and the public should be protected from scandellous charges and badly signed sites.
Unfortunately whilst there are plenty of reputable outfits, there are plenty of people that really shouldn't be doing the job! And they're the ones that have frankly caused all the bad press.
I know I keep going around in circles with the blue badge thing, basically the SIA have instigated rules upon VI licence holder. Regardless of what the DoT terms of the BB are, and whether the BB holder is in breach, the terms of the VI licence are clear - you can't clamp them. It's madness, IMO but the SIA really are rather "special" in that respect. They just repeat what is infront of them, no chance of reasoning, we've tried and failed..
My main issue was fraudulent use, we have alot of students that use relatives badges. We know, as they're seen on CCTV parking up and can be seen as the only occupant. When checked with the council, the badge relates to a woman in her 80's. Even though we know it's fraudulant use, we've been told by the SIA that it's off limits. Meanwhile a legitimate BB holder turns up and can't use the bays because they're all occupied!
Being honest BB holders are usually a very small proportion of the people that you'll have to deal with, so whilst not ideal, it's not the end of the world. The worst case scenario is that the one disabled BB holder that gets clamped, happens to be one of those people that "knows his rights" and loves a challenge. Not that it's a bad thing, but they're definitely aggravation to deal with! lol.
If you've ever got a query, you're more than welcome to give me a shout. It's been part of our business for 25 years - we deal with Universities and colleges etc, so everything is straight down the line, they wouldn't work with us if we weren't!
