Hello, I am a solicitor with over 15 years experience. I will try to help you with this.
I am working on it now.
He is in a difficult position here. At that level of breath reading he should have been offered a blood test as an alternative. You need to ask him why this wasn't offered. As far as talking to a solicitor is concerned all persons in police custody have the right to legal advice. although a breath test will not be delayed to enable legal consultation. The way solicitors are contacted through the police is that a detained person will be told on arrival by the Custody Sargent that he as the right to speak to a solicitor of his choice. If he has the contact details for one they will be contacted otherwise he will be referred to the duty solicitor scheme. If his access to a solicitor has been impeded then that could be very significant as could the apparent lack of the offer of a more accurate test through a blood sample.
A solicitor can help, as long as you get a solicitor who is either a specialist in road traffic or a good criminal solicitor with experience of road traffic cases. Your son may well want to get a copy of custody CCTV as this may show any breaches of your son's rights or highlight communication difficulties which might be relevant to the admissibility of the entire breath procedure. Has he been charged yet? He may qualify for legal aid if he is on low income (below £12.500).
The way a referral to the duty scheme works is that following a request, the police will call the duty solicitor call centre who will then call the solicitor on duty who will then call the police station to speak to the detained person.
As far private fees are concerned it does vary but I charge about £1,000 for a guilty plea and about £1,500 for a trial (+ VAT), this fairly standard in London. If your son wants to have a chance of avoiding a conviction and ban he will need there to be a technical defence available, that means he needs a solicitor who knows what they are doing.. I would reccomend early instructing of a solicitor to defend him.
He would probably qualify for legal aid. He should make an appointment to see a solicitor asap.
Te exchange you are requesting sounds odd. If he says yes (or rather signs that he wanst legaladvice) the duty siolicitor should be called immediately.
No that means £1,000 or £1,500. He may have a defence (the lack of legal advice, the lack of a blood test, the possible language issues can all possibly lead to a defence) and needs legal advice. In order to apply for legal aid he will need to make an appointment with a solicitor who will help him fill in the forms etc.
