On 4th September, Greenberg Traurig published a briefing outlining the position following the US Supreme Court’s decision in Murphy v. NCAA to strike down the Professional and Amateur Sports Protection Act. It points out that the effect of the decision was no to legalise sports wagering in the US, but removed the federal barrier prohibiting states and territories (other than a few grandfathered states, including Nevada) from legalising or offering sports wagering. However, the briefing points out that although individual states may authorise intrastate sports wagering, states may not authorise interstate sports wagering via wire communication (i.e. phone, internet). Interstate sports wagering via wire communication is prohibited by to the Federal Wire Act.
