Free Traffic Legal Advice

The Supreme Court (Beavis) ruled that the charge is not excessive.
You did not pay for 27 minutes.
You revealed the identity of the driver.
So you need other reasons, other than just not wanting to pay.

Thanks for that, any helpful advice?

As opposed to unhelpful advice?

You should reply to the Letter of Claim, without going overboard, and in due course you will need to submit a defence to a court claim, so think about what your defence will be.

If you defend a claim it is normal that DCB Legal will discontinue rather than paying the court fee.

But you should search the forum for similar cases also.
