The Supreme Court issued opinions in five argued cases today, bringing the total number of merits decisions up to 18, with forty* more to go (unless some get mooted out).

The pork producers argued this law unconstitutionally burdened interstate commerce and extraterritorialized California's regulatory preferences. A majority of the Supreme Court disagreed.
