Wine Industry Advisor reports that the US Supreme Court is set to consider a petition in Day v Henry, a challenge to Arizona’s restrictions affecting shipments from out of state wine retailers, and that the National Association of Wine Retailers has filed an amicus brief urging the Court to take the case. The release argues the federal appeals courts are split on how to assess these laws under the Twenty First Amendment, and says the outcome could clarify whether states can justify discriminatory retailer shipping limits by calling them part of the three tier system without evidence.
