Article in the LA Times about the possible impact in California of a recent SCOTUS case (about teeth whitening in North Carolina). Excerpt:
Hanging in the balance is the state's ability to regulate not only barbers and pet groomers, but also doctors and surgeons, nurses, chiropractors, optometrists, accountants, architects, lawyers, pest exterminators and security alarm installers. That's a partial list of California professional boards affected by the ruling, which is based on a 1943 precedent set in a case involving a marketing program for California raisins. The Supreme Court ruled then that state regulatory bodies comprising industry members are entitled to antitrust immunity only as long as their authority to set regulations is constrained and their decisions are subject to "active supervision" by state officials.
