The judge at a trial on indictment must be a professional judge (i.e., a High Court judge, circuit judge or deputy circuit judge, or recorder). The distribution of work between these various types of judge is described at 14.14. The prosecution must be legally represented; the accused usually chooses to be so, and will probably be able to obtain representation from the Legal Aid Agency. Although some solicitors now have rights of audience in the Crown Court, legal representation for trial on indictment still usually involves instructing solicitors who in turn brief counsel (see 14.21 to 14.23). The following Paragraphs deal with some aspects of the role of prosecuting and defence counsel, and their relationship with the judge. The discussion is based upon decided cases and also upon the Code of Conduct for the Bar. The Code does not have the force of law, but is of great persuasive value, and a barrister who conforms with its spirit cannot be guilty of a breach of professional discipline.
