The Supreme Court just ruled that states can’t enact protectionist alcohol laws. Congress should ensure that the same is true of cannabis in states where the drug is legal.The Supreme Court’s recent ruling in the alcohol-regulation case Tennessee Wine & Spirits Retailers Association v. Thomas corrects an 80-year-old jurisprudential error that raised the price of alcohol for generations. A misunderstanding of the 21st Amendment, which repealed Prohibition while granting states power to regulate the “transportation or importation” of alcohol, had allowed protectionist state laws to interfere with interstate commerce. In striking down Tennessee’s in-state-residency requirements for retail liquor licenses, the Court held that the Volunteer State can’t discriminate against outsiders willing to set up shop within its borders.
