never in this nation's history has Congress tried to repeal an amendment by passing a law.
Congress can pass a resolution to in effect repeal an amendment by calling for a constitutional convention or for a vote by the state legislatures (both acceptable methods) to add another amendment to repeal the previous one.
Prohibition was repealed by the Twenty-First Amendment, but it was passed by state constitutional conventions (yet was originally proposed by Congress).
ETA: OK, I see your earlier post noting Prohibition, but would you not agree that if Congress passes a resolution to amend the Constitution, and enough state legislatures ratify the amendment, then in effect, Congress and the legislatures have indeed passed a law (resolution) to amend the Constitution?
