An Idaho District Court judge has struck down that state鈥檚 law that criminalized undercover investigations of agricultural operations. These types of laws are known colloquially as 鈥渁g-gag.鈥�

In his decision, Judge B. Lynn Winmill writes that the Idaho case comes down to First Amendment protections for free speech.

鈥淎lthough the State may not agree with the message certain groups seek to convey about Idaho鈥檚 agricultural production facilities, such as releasing secretly recorded videos of animal abuse to the Internet and calling for boycotts, it cannot deny such groups equal protection of the laws in their exercise of their right to free speech,鈥� Winmill writes.

In 2014, animal rights group Mercy For Animals posted videos of workers at Bettencourt Dairies鈥� Dry Creek Dairy in Hansen, Idaho kicking, punching and jumping on cows. In response, the Idaho Dairymen鈥檚 Association drafted legislation to criminalize future undercover investigations. Idaho Governor Butch Otter signed the bill into law shortly after passage.

The Animal Legal Defense Fund filed suit against the state and enlisted to argue the case.

鈥淭his is a total victory on our two central constitutional claims,鈥� Marceau said following the decision. 鈥淎g-gag laws violate the First Amendment and Equal Protection Clause. This means that these laws all over the country are in real danger.鈥�

Montana, Utah, North Dakota, Missouri, Kansas and Iowa all have some form of an 鈥渁g-gag鈥� law on the books.
