New Jersey and Pennsylvania are opposing a new Justice Department legal memo that would expose state lottery systems to criminal prosecution.

In amicus briefs filed Wednesday, the states said their lottery and online gambling programs could face shutdown under a 2018 memo issued by the DOJ’s Office of Legal Counsel reinterpreting the Wire Act. The states expressed support for the New Hampshire Lottery Commission and a group of lottery vendors, who are asking the U.S. Court of Appeals for the First Circuit to uphold a 2019 decision setting aside that OLC memo.
