Our Founders' Warning: “Every government degenerates when trusted to the rulers of the people alone. The people themselves are its only safe depositories.” (Thomas Jefferson)

Agreement or Compact

“No State shall, without the Consent of Congress… enter into any Agreement or Compact with another State…” (US Constitution, Article I, Section 10, Clause 3). Explanation by US Senate: “States may come together to work on common problems, such as pollution of a river passing through several states, but the agreements or compacts they reach are subject to congressional consent.” (Supreme Court Review)
