The Foothill-DeAnza Community College District has again beaten back a legal challenge to Measure C, passed by district voters in 2006.
A lawsuit was originally filed challenging whether the measure conformed to state regulations earlier imposed by Proposition 39.
The college district won the lawsuit but that decision was appealed.
Measure C was approved by district voters in June 2006 by 65.69 percent of the voters. The challenge was that Measure C didn't meet Proposition 39's legal requirements of 55 percent for bond measures from school districts and needed a two-thirds vote, or 66.67 percent, to pass.
On Wednesday, the state's Sixth District Court of Appeals affirmed the earlier court's ruling.
Measure C would provide the college district with $490.8 million in general obligation bonds.
The legal challenge to Measure C was from Melvin Emerich and Aaron Katz. The latter has often filed lawsuits challenging tax measures. Besides Foothill-DeAnza, Katz has sued the Mountain View-Whisman School District, El Camino Hospital District, West Valley-Mission Community College District and the Campbell Union High School District, all unsuccessfully.
