A system of check and balances ensure that each branch as the authority to decide on certain kinds of issues although each branch often require cooperation from other branches if the decisions are to implemented successfully (Wood).
However, in the absence of these checks and balance, there would be a potential abuse of power from these arms of the government that would result to a tyrannical regime. Firstly, if the legislature had the powers to create any law that it desired, however malicious it may be, there would be no one to oppose it. This could lead to exploitation and infringement of the rights of the American citizens who would be defenseless against such unconstitutional laws.
Checks and balances are vital in providing an oversight over the actions of the executive. In absence of these checks and balances, the executive might abuse its powers by appointing incompetent, unqualified or corrupt people into public office in order to serve their own selfish interest . However, if the checks and balances do exist, the senate would reject such appointments so as to ensure integrity in the system. Furthermore, the courts can Judge the executives actions to be unconstitutional through the power of the judicial review.
In addition, the absence of checks and balances would lead to the rise of ambitious and unscrupulous office holders in some of these branches of government with the sole purpose of encroaching upon the powers and authority of other branches hence leading to a tyrannical concentration of powers (Wood).
In conclusion, checks and balances and separation of powers in the American government ensures accountability which translates into a policy making process that puts the interests of the minority along with those of the majority into serious consideration. However, this system is not flawless as at times it has been criticized for stalemate, gridlock and inefficiency. This
