The attorneys general of 13 states have asked the Supreme Court to block California’s law setting living space requirements for the hens that produce eggs sold in the state, the Associated Press reported.

Ralph Henry, director of litigation for The Humane Society of the United States, said he expects the effort to fail.

“Opponents of California’s animal welfare laws are grasping at straws in a legal Hail Mary to try to force substandard and inhumane products onto California consumers. We expect this latest legal action will fail just as every other attempt to invalidate these common sense food safety laws in California has,” Henry said.
