Use the complete GovInfo Statutes at Large granule, especially 48 Stat. 16–20.
The Cullen–Harrison Act was approved on March 22, 1933 and took effect fifteen days later, on April 7. It removed specified fermented beverages containing no more than 3.2 percent alcohol by weight from central National Prohibition Act restrictions while preserving state and local prohibitions; it did not legalize whiskey or repeal the Eighteenth Amendment.
Full statute reviewed. April 7 is the calendar result of the statute’s fifteen-day effective clause and is independently confirmed by Constitution Annotated.
Use alcohol by weight, not alcohol by volume. Call this a partial statutory relaxation or beer-and-light-wine reopening, not full Repeal and not authorization of distilled-whiskey production.
The statute’s approval clause fixes March 22; § 9 supplies a fifteen-day effective period; §§ 1 and 3 define the beverage scope and 3.2-percent-by-weight ceiling; §§ 4, 6, and 7 preserve permit and state-law constraints.
Publication-safe as a discrete precursor event in the 1933 legal transition.
