Then they should be disbarred, simple as that - Raymond is perfectly correct in what he says a solicitor should do. Any solicitor has a duty to the court and to the truth - if the solicitors you know are breaking that then they should be investigated and if the allegations are true then have their right to practice revoked.
What they won't do is directly lie. Even if they know he is guilty. I never said he won't defend the client, i said he cannot lie. There is a difference, which you missed.
I'm not saying they lie (although they migh, who knows), I'm just saying they know their client is guilty and use the facts to put as much reasonable doubt into the defence case as possible.
Or are you saying if the defendant says he did it, the solicitor has to tell this fact in court?
In my opinion you can know your client is guilty by been told it and still defend him without lying.
Case in point as follows:
Client drinking in the pub, drives home. Police want to pull him over, he doesn't stop and parks outside his house leaving his engine running and runs inside the house and was downing a large glass of whiskey when the police caught up with him. Of course, he later failed the breath test.
He hired a top notch solicitor from London who case to defend him in the local rural court.
In court the solicitor had the policeman on the stand and asked him how full the glass was when they caught his client. The policeman indicated how much. The solicitor then brought out many different height and width glasses and went on to prove that the quantity of liquid each glass held varied greatly even to the same height so his client could have drunk enough to put him over the drink drving limit.
The prosecution failed to keep the glass from his house so because there sufficient doubt he got let off the drink driving charge.
Now I know for a fact that he knew his client was guilty and he specialises in getting people off drink driving/speeding. However, he didn't need to lie in court to do this and unlikely anybody is going to ask him whether his client is guilty?
