A highly accomplished federal and state trial and appellate court advocate, Robert Mandel has more than three decades of experience vigilantly, zealously, and effectively representing clients in business and regulatory disputes both domestically and internationally. Recognized in The Best Lawyers in America© and other peer review journals, Mr. Mandel litigates cases in trial and appellate courts throughout Arizona and beyond. He has worked on some of the largest, most complex cases to hit the docket in Arizona, New York, and other states, many of which have been high-profile. He is often called upon to collaborate with trial teams at other law firms as well when they are in need of additional firepower.

Mr. Mandel is a veteran business litigator. Over the past 31 years, he has represented an array of public and private companies and individuals in disputes involving claims of statutory, common law, and constructive fraud, negligence and negligent misrepresentation, breach of fiduciary duty, business interference, unfair competition, false advertising, trademark infringement, trade secret misappropriation, shareholder and corporate claims, conversion, breach of private and public contracts, unjust enrichment, fraudulent transfer, construction design defect, together with a variety of real property claims. Mr. Mandel’s clients represent a wide variety of traditional and emergent industries and business sectors, including Arizona’s regulated adult-use and medical marijuana industry.

Like his trial court cases, Mr. Mandel’s appellate engagements frequently involve a panoply of business, constitutional, or public law issues, conflicting legal doctrines and public policies, novel legal questions, and robust trial court records. He spearheads appeals from final judgments, preliminary injunctions, and other interlocutory decrees, petitions for writs of certiorari or mandamus, appellate motion practice, and amicus curiae briefs. Astute clients avail themselves of Mr. Mandel’s appellate experience well before their trial court proceedings have ended.
