Answer 2

The Founding Fathers added a system of checks and balances to the principle of separation of powers written into the Constitution. The system allows each of the three branches to check and control the powers of the others. The system works in several different ways. Congress can pass laws but the President can check the legislative power of Congress by the use of the veto power. The veto power is, in turn, balanced by the power of Congress to override a presidential veto by a two-thirds vote in each house. The federal judiciary can limit and control the power of the legislature via its power of judicial review--the power to declare laws unconstitutional. This judicial power is in turn balanced via the presidential power to appoint federal judges. That power is balanced by the Senates power to approve appointments. The major purpose of the Checks and Balances system was to prevent any one branch from becoming too powerful. The system has also had a practical effect by creating a system of shared powers among the three branches. For our system of government to operate effectively, all branches must work together.
