Implications of Wayfair

This article deals with the decision of the US Supreme Court of 21 June 2018, No. 17-494 (Wayfair v. South Dakota), which overruled decades of precedent to declare that the Constitution did not bar a US state from imposing obligations on remote sellers to collect tax on sales they made into the state, even if they had no physical presence there. This article describes Wayfair and provides some cautions about what it means for the US states and the rest of the world, especially Europe.
