Read FTCR’s "friend of the court" brief in the Donabedian v. Mercury Insurance case, filed with the California Supreme Court in June 2004, which sets forth FTCR’s view that Proposition 103 requires full public disclosure of all material required by the CDI.


Defending voter-approved Proposition 103 against an attack by an insurance company and its allies in Sacramento, a California Court of Appeal ruled today that a 2003 law signed by then-Governor Gray Davis was an unconstitutional amendment to the initiative because it conflicted with the initiative’s ban on auto insurance surcharges targeted at previously uninsured customers. Senate Bill 841, invalidated today by the Court, was authored by current Senate President pro Tempore Don Perata and sponsored by Mercury Insurance, a major campaign donor to both Perata and Davis. Read our press release on the subject.

Mercury Insurance was behind an initiative for 2006 California ballot which would have repealed this important protection in Prop. 103, but Mercury backed-down and will not be pursuing this unfair initiative.
