That's kind of a broad question.
Congress doesn't usually pass laws; they pass bills or "acts." An act becomes a law when the President signs it. If the President doesn't like the bill/act, he (or she) can veto it, or refuse to sign it and send it back. Then Congress has to fix the act or start all over from scratch. If a lot of Congressmen feel strongly about passing the law, they can vote to override the veto. If two-thirds of the Senate and two-thirds of the House of Representatives agree, they can make a bill/act a law even if the President doesn't like it.
If the President does sign an act into law, Congress can vote to amend (change) the law or repeal (unmake) it, but the House of Representatives and the Senate have to agree by voting. If a simple majority (a little more than half) of each part of Congress agrees, then they can change or "unmake" the law.
The law can also be challenged in the federal court system. The Supreme Court may decide a law is unconstitutional and nullify (unmake) it.
So, yes, different parts of government have some ability to stop a law from being passed or to repeal or overturn (unmake) it.
None. This is because to be a "law" it MUST have been passed by congress.,
In government a bill is a proposal that is considered for becoming a law. If a bill is passed by Congress and signed by the president it becomes a law.
Congress cannot veto a law. Any law must be written and passed by Congress in the first place. The president can then veto it. Congress can override the veto with a 2/3 majority. After a law is passed, the Supreme Court can strike it down if they declare the law unconstitutional.
the congressThe legislature branch enforces them so the judiciary branch must make them. After that the law is passed to Congress where they and the president must pass or decline the bill. If it is passed and approved it becomes a law.
Yes, the Supreme Court can overturn a law passed by Congress if it is found to be unconstitutional.
The president vetoes a law passed by Congress, but Congress overrides the veto with a two-thirds majority vote. (APEX)
The congress passed a law making it a crime to criticize the government or to interfere with the war.
Congress passed a law declaring the third Monday of February as Presidents' Day.
If the law is passed by votes of fewer than 2/3 of Congress, he can simply refuse to sign it into law, that is, veto it.
Only Congress has the power to make laws, so if the President want a law passed, he has no choice but to prevail upon Congress to pass it. That is how the US Constitution has set up the government to work.
In the United States the US Congress initiates bills that if passed by both houses of Congress, the House of Representatives and the Senate. If the bill passes both branches of the Congress, and if the President signs the bill into law, then it's the duty of the Executive branch to implement the new law.
