So you didn't have a Solicitor at the time? Because touting for business is only an issue if the person is already represented.
If your bother mentioned to his plumber friend that your sinks were blocked and he offered to have a look at them, would you have also thought that he was committing an offence?
There won't be any Solicitors touting for business from Graham Dwyer in relation to a possible civil case if he wins this appeal, because he is already represented. If another Solicitor was to approach him they would find themselves up on disciplinary charges.
Is that clear enough for you?
If someone was an injured party but didn't even think to make anything of it til a solicitor turned up uninvited and said to them "You have a very good case, you should sue them and get compensation" is that not touting for business?
