The separation of powers principle functionally differentiates several types of state power (usually law-making, adjudication, and execution) and requires these operations of government to be conceptually and institutionally distinguishable and articulated, thereby maintaining the integrity of each.^[1] To put this model into practice, government is divided into structurally independent branches, each particularly suited to its function^[2] (most often a legislature, a judiciary and an administration, sometimes known as the trias politica). When each function is allocated strictly to one branch, a government is described as having a high degree of separation; whereas, when one person or branch plays a significant part in the exercise of more than one function, this represents a fusion of powers.
