What does "Advice and Consent" mean?
A great day to you, Lena!
"Advice and consent" is used in the United States Constitution. This is an important part of the checks and balances among the three branches of government in the said country (e.g., legislative, executive, and judicial).
This phrase defines the roles and responsibilities of the Senate in appointing officials by the President and in the ratification of treaties. It is the authority of the US Senate to approve or reject any treaty to which the United States is a proposed signatory.
I hope this sheds some light on your inquiry.
