Brockovich and Masry filed suit against the Beverly Hills Unified School District in 2003, in which the district was accused of harming the health and safety of its students by allowing a contractor to operate a cluster of oil wells on campus. Brockovich and Masry alleged that 300 cancer cases were linked to the oil wells. Subsequent testing and epidemiological investigation failed to corroborate a substantial link, and Los Angeles County Superior Court Judge Wendell Mortimer granted summary judgment against the plaintiffs. In May 2007, the School District announced that it was to be paid $450,000 as reimbursement for legal expenses.
