Translation:The lawyers listen to the judge.
A lawyer is a general term that covers both solicitor and barrister (advocate). A solicitor is usually the first person that a member of the public will go to with their legal problem. A solicitor will often refer the work to a barrister for specialist advice or to appear in court to represent the client. It is also possible for certain solicitors to appear in court as advocates (barristers), if they have higher rights of audience. The judiciary is drawn from both branches of the profession.
This is the difference between the British English terms. In America we use lawyer and attorney, and they are essentially interchangeable, but you could think of attorney as the equivalent of a barrister, since in court each side has an attorney but when you first seek legal advice you ask for a lawyer. However, both are referred to by both names, and they aren't separate professions.
Edit: In America we use the word "solicitor" for a very different meaning than in Britain. When someone comes to your door or calls your home phone offering services or preaching or selling something, they are a solicitor and you may see "no solicitors" signs in people's doors or windows.
