A state appellate court has overturned a 1986 initiative sponsored by tax activist Howard Jarvis that requires voters to approve all taxes imposed by local governments.

In declaring Proposition 62 unconstitutional, the 4th District Court of Appeals ruled Thursday that requiring voter approval constitutes a "gross interference with the fiscal responsibility of local governments.""It's a sad day for the California taxpayer," said Joel Fox, a spokesman for the California Tax Reduction Movement in Los Angeles. The anti-tax group campaigned for Proposition 62 after Jarvis died on Aug. 12, 1986. The measure was approved by state voters in November 1986.

The appellate court reversed a decision by a Santa Ana Superior Court judge in January, who upheld Proposition 62 against a legal challenge brought by the city of Westminster and said the measure was "constitutional and enforceable."
