The US Congress Cannot Reassign Its US Constitutional Duties and Authorities, or Any One of Them, Such as Imposing Tariffs and Making or Declaring War, to the US President

The US Congress Cannot Reassign Its US Constitutional Duties and Authorities, or Any One of Them, Such as Imposing Tariffs and Making or Declaring War, to the US President or US Judiciary, But Questionably and Doubtfully It Might Be Able to Somehow Reassign Them, that is, Divest Itself of Them, by the Arduous Amendment Process of the US Constitution Specified in the US Constitution

Congress cannot reassign its duties and authorities prescribed and assigned specifically to it in the text of the supreme law of the USA of the governance supreme Constitution of the USA, with only the possible exception of an amendment of the US Constitution through the amendment process to the US Constitution specified in it to do so. Congress cannot, as well, legally delegate its constitutional rights, duties and authorities to another branch of government or a member or function thereof, which, if it wrongfully did, would be to breach or collapse the US Constitution's intended and delineated separation of the mutual checks-and-balances governance powers of the three separate and co-equal branches of the federal government it established and authorizes to exist as such.

However, Congress can delegate by legislation, without a constitutional amendment, areas of its rights and duties of constitutional governance jurisdiction, when it is in the national interest and service, for it to do so, to non-partisan experts where expertise is verifiably vital or highly beneficial to the nation in common, such as to its overall comity, health and/or welfare.
