- U.S. Supreme Court
- Lead appellate counsel in Sprietsma v. Mercury Marine (2002), a unanimous U.S. Supreme Court decision on behalf of man whose wife was killed when she was repeatedly struck by an unguarded boat propeller. In a rare decision affirming tort victims’ rights to hold manufacturers accountable for dangerous products, the Court held that the Federal Boat Safety Act does not preempt state common-law claims against a boat engine manufacturer for failing to install a propeller guard on the engine of a recreational motorboat (Leslie’s oral argument in Sprietsma can be accessed via this link).
- Co-lead appellate counsel in Geier v. American Honda Inc. (2000), a U.S. Supreme Court decision finding, by a 5-to-4 vote, that federal law impliedly preempts claim that car was defective because it lacked an airbag but that federal law does not expressly preempt any state law claims.
- Co-counsel in Freightliner v. Myrick (1995), a unanimous U.S. Supreme Court decision finding that federal law does not preempt design-defect claim against truck manufacturer for failing to install anti-lock brakes in trucks.
- Co-lead appellate counsel in Monsanto v. Hardeman (9th Circuit May 2021), the first (and to date only) federal appellate decision in the country affirming the rights of cancer victims to sue Monsanto for injuries caused by Roundup. In upholding an $80 million jury verdict on behalf of Ed Hardeman (later reduced to $25 million), the Ninth Circuit rejected Monsanto’s argument that failure-to-warn claims involving Roundup are preempted by federal law, paving the way for thousands of other victims to obtain justice from Monsanto.
- Lead counsel in Cherry v. Dometic Corp. (11th Cir. January 2021), which restored the viability of class actions in the Eleventh Circuit by rejecting a “heightened” ascertainability standard that required proof, at class certification, that all class members can be identified in an administratively feasible fashion without the use of self-identifying affidavits. Leslie’s oral argument in Cherry can be accessed via this link.
- Lead appellate counsel in Noel v. Thrifty (CA Supreme Court 2019), which yielded a unanimous class action ruling from the California Supreme Court rejecting a strict version of the so-called “ascertainability” requirement and restoring the viability of consumer and worker class actions against wrongdoing corporations. Leslie’s oral argument can accessed via this link.
- Co-lead counsel before the California Supreme Court in H. v. Novartis, holding that brand-name drug manufacturers can be sued for failing to warn of the dangers of mislabeled, generic versions of their drugs. The decision rejected over 100 reported appellate decisions from state and federal courts nationwide. Leslie and co-counsel Ben Siminou were awarded the Pound Civil Justice Institute’s 2018 Appellate Advocacy Award for their work on the case.
- Lead counsel in Quesada v. Herb Thyme Farms, Inc., a unanimous decision upholding consumers’ rights to bring a class action against an organic grower for mislabeling its conventionally grown herbs as “organic.” The decision remains the only appellate decision in the country to hold that federal law—the Organic Food Production Act of 1990—does not preempt state consumer fraud claims on behalf of individuals who were defrauded by the use of the “USDA organic” label on conventionally grown food.
- Co-counsel for plaintiffs in a series of lawsuits successfully challenging so-called “ag-gag” laws that seek to criminalize whistleblowing in animal agriculture and elsewhere.
- Co-lead appellate counsel in S. Airways v. McCutchen (U.S. Court of Appeals for the Third Circuit and U.S. Supreme Court), an ERISA reimbursement case yielding a landmark ruling from the federal appellate court limiting the rights of an ERISA plan to recover medical expenses from an injury victim who obtained compensation from a third party.
- Co-lead appellate counsel in CGI v. Rose (U.S. Court of Appeals for the Ninth Circuit), an ERISA reimbursement case yielding a unanimous ruling from the U.S. Court of Appeals for the Ninth Circuit limiting the rights of an ERISA plan to recover medical expenses from an injury victim who obtained compensation from a third party.
- Lead appellate counsel in Southern California Gas Leak Cases (CA Supreme Court 2019), a class action lawsuit arising out of the biggest methane gas well leak in United States history. Leslie’s rebuttal argument in the case can be accessed via this link.
- Lead appellate counsel in McNair v. Johnson & Johnson before the West Virginia Supreme Court of Appeals on whether brand-name prescription drug manufacturers can be held liable for injuries caused by generic versions of their drugs.
- Counsel for the Center for Food Safety in Animal Legal Defense Fund v. Wasden (U.S. Court of Appeals for the Ninth Circuit), a successful challenge to an Idaho “ag-gag” law that criminalized undercover recording in industrial agricultural facilities, including factory farms and slaughterhouses.
- Co-counsel for the Animal Legal Defense Fund in National Meat Association v. Harris (U.S. Supreme Court), an effort to preserve a California law designed to prevent the abuse of pigs and other livestock who become non-ambulatory on the way to the slaughterhouse.
- Lead counsel in Drelles v. MetLife (U.S. Court of Appeals for the Third Circuit), a federal appeal yielding a unanimous ruling that consumers who opted all of their claims out of a nationwide class action settlement with Metropolitan Life Insurance Company (MetLife) cannot be barred from fully prosecuting their individual cases against the company.
- Lead counsel in Priester v. Ford Motor Company (South Carolina Supreme Court), a federal preemption appeal on behalf of the mother of a young man who died when ejected from a passenger truck during a rollover accident.
- Co-counsel in Aguayo v. U.S. Bank (U.S. Court of Appeals for the Ninth Circuit), a federal preemption appeal holding that federal banking law does not preempt state debt-collection laws.
