Since the Constitution places the power and responsibility for passage of legislation with the Congress, passing a law is more an example of the basic function of the legislative branch than an example of checks and balances. However, it could become an example of checks and balances if Congress passes a law, the President vetoes it, and Congress then overrides the President's veto as provided in the Constitution.
Yes.
yes
checks and balances
Yes. The framers wanted to make sure that the Legislative Branch could not become too powerful by creating the veto power for the president. However, the President's veto can be overturned with a 2/3 majority vote from both houses of congress. Also, the supreme court can overturn any legislation during a process called Judicial Review, limiting the power of the other two branches.
One of the key principles in American Government are checks and balances. Checks and balances is a process that each branch of the government can check the actions of the others. The three branches of government are the Judicial, Legislative, and Executive branches. Basically what this process entails, is when Congress enacts a law, the president can veto the law that Congress passes. The Supreme Court has the power to decide the laws Congress and the president pass to be constitutional or unconstitutional. Finally, the president is the one to appoint the justices of the Supreme Court, with consent of the Senate. That is a basic overview of the Checks and Balances that take place in American Government. Now the question is, does the system always hold true?
One way the Constitution reflects the principle of checks and balances is in the way bills are passed. Every Bill that passes the House of Representatives and the Senate has to be signed by the President before it becomes law. If the President does not sign the bill, it returns to the Congress to be reconsidered.
Congress has to pass a law before it goes to the President. The President can veto the law. Congress can then over rule the president with a 2/3rds majority.
A bill is written and starts in the house. It goes to committee is evaluated and passes committee. It then goes to the full House for a vote. It passes the house. Now, it goes to the Senate. The Senate sends it to committee. The committee passes it and it goes to the full Senate. They pass the bill. It now goes to the president. He can sign it, veto it, or do nothing. This is a real life example of checks and balances.
The constitution is divided into three branches and each branch has powers that depends upon the other. If Congress sends the president a bill that is not for the "common good" of the people, is against the constitution, or passes a bill that favors a special group the president can veto the bill. If the president wants to appoint a ambassador he has to have Congressional approval. These are examples of checks and balances. One branch checks the other in running the government.
This is the balance of power at work.
A bill passes, in theory, with a majority of 50% + 1. If a President opposes a bill, he can veto it. Then the only way it can become law is if both houses of Congress vote by a 2/3 majority to override the veto.
The power of congress is limited by a system of checks and balances. Congress is divided into The House and The Senate. If a proposal passes both of these, then the President has the power to veto the proposal.
To start with the second question first, the various checks and balances between the the three US branches of government are used on an almost daily basis. It is part of the natural operation of the US government that the various branches will exercise all of their powers.As for what the particular checks on power are in the United States, a complete list of those can be found on the following webpage: US Constitution Online
