HGST, Inc. v. County of Santa ClaraAnnotate this Case
HGST bought manufacturing fixtures, machinery, and equipment for $2.4 billion in 2002. The Santa Clara County Assessor annually imposed escape assessments (corrections to assessed value on the local property tax roll) on the property, 2003-2008. HGST challenged the assessor’s findings. The Assessment Appeals Board (AAB) issued findings in 2012 largely adopting the assessor’s findings. HGST filed an unsuccessful claim for a refund of $15 million with the Board of Supervisors. In 2014, HGST filed suit, seeking a refund. The court ruled in favor of the county.
The court of appeal affirmed in part, rejecting arguments that the trial court: erred by reviewing the entire case in blanket fashion under a substantial evidence standard rather than examining each individual claim to determine which standard of review should apply; erroneously failed to review certain legal challenges to the valuation methodology applied by the AAB; and erred by upholding the AAB’s decision not to apply the “purchase price presumption” set forth in Revenue and Taxation Code section 110. The court reversed in part. The trial court erred by upholding the imposition of interest on the escape assessments under section 531.4; it made no findings on what portion of the property was reported accurately or to what extent the escape assessments were caused by HGST’s purported failure to report the property accurately.
