On May 11, 2023, the Supreme Court blessed California’s imposing its will on other States. This was a setback for WLF, which filed an amicus brief supporting the petitioners. California allows pork to be sold in the State only if the pig’s mother was kept in a group pen with at least 24 square feet of space per sow. WLF’s brief argued that this de facto extraterritorial application of California law violates horizontal federalism principles. The brief also explained how it could lead to increased food prices and hunger worldwide.
