Do California environmentalists have the right to tell you how to build your barn in Iowa? Do Californians have the right to eat bacon? Those questions and more will now be put in front of the highest court in the land.

The Supreme Court has taken up the question of the legality of California’s Proposition 12, which banned the sale of chickens, veal calves, and pigs in California unless they were raised in nice, cozy, environmentalist-approved enclosures. Though San Francisco animal rights activists have no farm experience outside of singing “Old MacDonald,” they have somehow decided that they know how farmers should lay out their barns and animal enclosures.
