People vs Freeman is the California case by which porn-production was protected in that state. Wikipedia says

Quote:

The State of California unsuccessfully tried to have this judgment overturned by the United States Supreme Court. Justice Sandra Day O'Connor denied a stay of the California Supreme Court's judgment, finding that its ruling was founded on an independent and adequate basis of state law. The full Court subsequently denied the petition for review.

As a result of this precedent, the making of hardcore pornography was effectively legalized in California.
