The return of Dutch rule reignited conflict between the planters of Essequibo and Demerara and the Dutch West India Company. Disturbed by plans for an increase in the slave tax and a reduction in their representation on the colony's judicial and policy councils, the colonists petitioned the Dutch government to consider their grievances. In response, a special committee was appointed, which proceeded to draw up a report called the Concept Plan of Redress. This document called for far-reaching constitutional reforms and later became the basis of the British governmental structure. The plan proposed a decision-making body to be known as the Court of Policy. The judiciary was to consist of two courts of justice, one serving Demerara and the other Essequibo. The membership of the Court of Policy and of the courts of justice would consist of company officials and planters who owned more than twenty-five slaves. The Dutch commission that was assigned the responsibility of implementing this new system of government returned to the Netherlands with extremely unfavorable reports concerning the Dutch West India Company's administration. The company's charter, therefore, was allowed to expire in 1792 and the Concept Plan of Redress was put into effect in Demerara and Essequibo. Renamed the United Colony of Demerara and Essequibo, the area then came under the direct control of the Dutch government. Berbice maintained its status as a separate colony.
