The document discusses the separation of powers as it relates to Commonwealth Caribbean countries. It outlines that there are three arms of government - the executive, legislature, and judiciary - with the executive formulating policy, the legislature making laws, and the judiciary adjudicating disputes. The concept of separation of powers originated with Aristotle and was later expanded on by Montesquieu, who argued the powers must be separated to prevent arbitrary rule and tyranny. While the UK model has near-complete fusion of the executive and legislature, Commonwealth Caribbean countries aim to maintain independence between the branches through checks and balances.
