This joint resolution proposed the 21st Amendment. A joint resolution is a formal opinion adopted by both houses of the legislative branch. A constitutional amendment must be passed as a joint resolution before it is sent to the states for ratification.
This resolution was passed on February 21, 1933, and sent to the states for ratification that same day. Ratified on December 5, 1933, the 21st Amendment is unique for two reasons. It is the only amendment to repeal another amendment (the 18th, which legalized Prohibition). Secondly, it was the only amendment to be ratified by state conventions assembled specifically to vote on it, rather than by state legislatures.
