Document 15: Ghana Bar Association: The British parliament established the Supreme Court of Judicature for the Gold Coast Colony in 1876, with a Chief Justice and no more than four Puisne Justices. John Mensah Sarbah was the first native of Ghana to be called to the bar by Lincoln's Inn in 1887. The legal system was based on that of England, in which solicitors provide legal advice and prepare legal documents while barristers act as advocates in court. However, this division was not observed in practice in Ghana, and in 1960 an act abolished the distinction. Until the Ghana School of Law was established in 1958, all lawyers were trained abroad, almost always at the Inns of Court in England. As of 2011 there are about 2,500 practicing lawyers, although not all have registered as members of the Bar Association.
