Professor Chad Hart was interviewed by WHO-TV 13 for the story "How California animal confinement rule may harm Iowa pork sales, industry," which focuses on a 2018 law that would allow California to ban the sale of pork products from states that use gestation crates. The law is now before the Supreme Court.
Hart told WHO-TV 13 "This is a tough one and you can see that even with the Supreme Court argument they’re not coming out with a ruling today, tomorrow, it’s going to be a while they’re going to chew on this for a while. There are a lot of questions to deal with here, because it does walk this fine line between state control over the markets within their own borders, versus the need for businesses to have uniform rules across the country in order to make interstate trade.”
