The April 13 ruling looms large as other state legislatures grapple with ever-climbing drug prices.
Similar price-gouging legislation has been introduced in at least 13 states this year, though none of those measures became law, according to the National Conference of State Legislatures (NCSL). Three other bills failed to gain passage.
The NCSL also cited the law in a March advisory for states seeking new approaches to regulating drug prices.
The court’s finding could have a chilling effect on such efforts, especially as more state legislatures wrap up business for 2018.
