Case History

Unfair Competition Defense — Ms. Hanna represented a former executive VP (defendant) of a title insurance company (plaintiffs) against allegations that he breached his contract and stole trade secrets. The defendant was hired by the plaintiffs with a promise of receiving 5% ownership, but left to go back to his former employer, a competing title insurance company, after the promises didn’t come to fruition. Plaintiffs accused our client of wooing its customers, claiming $14 million in lost profits, and $250 million lost value to the company. After a seven-week trial, a jury found against the plaintiffs on its claims, and awarded M&R’s client $50,000 on his breach of contract counterclaim.
Insurance Employment Class Action — A prominent insurance brokerage was held liable for violating California’s wage and hour overtime laws, among related issues. Facing a $42 million judgment, the client retained M&R. After conducting in-depth analysis, M&R designed a defense around the argument that the $42 million judgment should be reduced to $1.2 million because of a conflict in federal and state employment laws that were being misapplied by the plaintiffs' lawyers. Specifically, the plaintiffs contended that pursuant to California’s Business & Professions Code section 17200 (Unfair Competition Laws), it could expand the “class” under federal law. M&R countered that the United States Congress changed the law in the 1930’s, and again in 1949, to prohibit the expansion of federal law as being applied in this case. After intense litigation regarding the legislative intent, the federal court agreed with M&R’s argument, limiting the judgment to $1.2 million. On appeal, the Ninth Circuit upheld the ruling.
Insurance Consumer Class Action — M&R successfully defended a national insurance brokerage against a class action alleging that the recording of customer telephone calls without proper disclosures was a violation of California statutes. At that time, California courts were interpreting this type of conduct as illegal and holding to the statutory damages of $5,000 per call. In this case, there were approximately 600,000 alleged calls and potentially billions of dollars in statutory damages. M&R designed a defense predicated on the legislative intent of the statute dating back to 1967, arguing that the statutes at issue were designed to protect against “industrial espionage.” After intense argument, the court agreed with the defense and dismissed the case in favor of our client.
