California Nuisance Wildlife
​Control Operators Association

"We are not imposing our view of a well-functioning market on the people of California. Instead,  we invalidate only the
​State legislature’s naked attempt to raise a fortress protecting Branch 2 Structural Pest Control Licensees at the expense of
​California's private Wildlife Control Operators who are similarly situated, but who do not use pesticides for the control
​of vertebrate pests in structures․"

OPINION,  Merrifield v. Lockyer, 547 F. 3d 978-992 (9th Cir. 2008)

In 2004, the CNWCOA filed a lawsuit in federal court challenging the constitutionality of a structural pest control occupational licensing regulation. It ultimately won that case in 2008 at the 9th U.S. Circuit Court of Appeals. The Court's OPINION & ORDER in that case affirmed the plaintiffs' constitutional right to earn an honest living as Wildlife Control Operators without being subjected to arbitrary or unreasonable governmental interference.

In 2009, the U.S. District Court in San Francisco issued a PERMANENT INJUNCTION against members of the California Structural Pest Control Board prohibiting each of them, their successors, their employees and their associates from making any attempt to enforce this unconstitutional law against the prevailing plaintiffs.
