A concurrent resolution (labeled H.Con.Res. or S.Con.Res.) is a measure both chambers of Congress pass, but it isn't presented to the president and doesn't become law. Congress uses concurrent resolutions for internal business — setting the annual budget framework, scheduling joint sessions, or expressing the collective opinion of both chambers on policy matters.
The War Powers Resolution gives concurrent resolutions a special role: under 50 U.S.C. section 1544(c), Congress can direct the president to withdraw military forces through a concurrent resolution. The framers of the War Powers Resolution chose this mechanism deliberately — because a concurrent resolution doesn't go to the president, it can't be vetoed. That design was meant to give Congress an unblockable tool to end military operations.
However, the Supreme Court's 1983 decision in INS v. Chadha raised serious constitutional questions about whether Congress can use a concurrent resolution to compel executive action. Chadha struck down the "legislative veto" — a one-chamber mechanism for overriding executive decisions — and its reasoning may apply to concurrent resolutions that direct presidential action. This legal uncertainty has never been resolved in the war powers context.
Concurrent resolutions sit at the intersection of congressional procedure and war powers. Whether Congress can use them to force troop withdrawals — without the president's signature — remains an open constitutional question. The answer determines whether Congress has a veto-proof check on presidential war-making or whether the president can block withdrawal demands.
People often confuse concurrent resolutions with joint resolutions. Joint resolutions go to the president, can be vetoed, and carry the force of law. Concurrent resolutions skip the president entirely and don't have legal force on their own — which is both their advantage (no veto) and their weakness (questionable enforceability).
