In what will likely give a boost to some niche e-commerce players, the U.S. Supreme Court struck down state laws barring consumers from buying wine and having the seller ship it across state borders, the E-Commerce Times reports. The 5-4 decision dealt specifically with state laws in Michigan and New York. The court ruled that the existing laws were discriminatory and anti-competitive. The ruling paves the way for direct-to-consumer, cross-border wine sales in previously prohibited states: from Arizona and Arkansas to Massachusetts, Ohio and Pennsylvania.
