Document 2: 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.

Document 5: Gold Coast (British colony): In 1482, the Portuguese came to the continent for increased trade. They built the Castle of Elmina, the first European settlement on the Gold Coast. From here they acquired slaves and gold in trade for European goods, such as metal knives, beads, mirrors, rum, and guns. News of the successful trading spread quickly, and British, Dutch, Danish, Prussian and Swedish traders arrived as well. The European traders built several forts along the coastline. The Gold Coast had long been a name for the region used by Europeans because of the large gold resources found in the area. The slave trade was the principal exchange and major part of the economy for many years. In this period, European nations began to explore and colonize the Americas. Soon the Portuguese and Spanish began to export African slaves to the Caribbean, and North and South America. The Dutch and British also entered the slave trade, at first supplying markets in the Caribbean and on the Caribbean coast of South America.

On 6 April 1872, the Dutch Gold Coast was, in accordance with the Anglo-Dutch Treaties of 1870–71, ceremonially ceded to the United Kingdom.
