The principle describes a system of shared powers among different branches of government, wherein each branch can limit the actions of the other two branches. This ensures that no single branch becomes too powerful. An example includes the power of the legislative branch to impeach the executive or judicial branch, the executive branch’s ability to veto legislation passed by the legislative branch, and the judicial branch’s power to declare laws or executive actions unconstitutional.
This framework is fundamental to maintaining a separation of powers and preventing tyranny. It promotes a balanced government where power is distributed and accountability is enforced. Historically, the concept evolved from concerns about concentrated authority and the desire to protect individual liberties and prevent governmental overreach.
