Please help me on this .... I'll love you forever haha?

Who has the power to try to bring to trial all impeachments? What is the length of the term of office for justices of the United States Supreme Court? Who has the power to resolve issues involving national laws? Who has the power to settle disputes between different states? How many membres of the Supreme Court are there? What can the legislative branch do if the president vetoes a bill? Who has the power to review all laws and treaties of the United States? Who must approve all judges? Who must approve any treaties that are made wieth foreign countries?

Congress has the mandate in law to impeach officials.
Justices of the Supreme Court serves until 65 years old.
Congress has the power to amend and repel national laws.
There are at least 15 Supreme Court Justices in most countries.
The Legislature can veto the act of the President by 2/3 votes.
The Supreme Court has the power to review all laws & treaties.
The Judicial Bar Council approves the appointment of judges.
The President approves all treaties with other countries.

Well the Justices are elected for life. The house of Representatives impeach people. The whole government passes laws as well as settling disputes between states. there are nine justices on the supreme court. The legislative branch resubmits it in a different context and the president who vetoed it is often out of office and there is some strange thing about a percentage of the branch being for it but I don't really get that part. Supreme court reviews but the executive branch signs them originally. I think the people elect the justices or the president appoints them but I think the residents of the U.S. Elect them. President again.

P.S. I think I answered all your questions in order in case you get confused.
