All 13 states had ratified, or approved, the Articles of Confederation. Within the next few years, however, it became clear that the Articles had serious problems. To begin withk,the Congress could not pass a law unless 9 states voted in favor of it. Any attempt to amend, or change, the Articles required a unanimous vote of all 13 states. Even when the Congress managed to pass laws, it could not enforce them, unlike the state constitutions, the Articles did not provide for a governor or for courts.
