He served as the editor-in-chief of the American Bar Association's Franchise Law Journal from 1988 to 1993, and authored the New York forms of jury instructions on franchise law. His articles for franchisees have appeared in Entrepreneur and Franchise Update, and he has been quoted by The Wall Street Journal, New York Times and Business Week. He is presently a member of the Governing Committee of the ABA Forum on Franchising.

His writings have been cited by several courts, including the United States Supreme Court.

Mr. Garner has tried franchise cases involving claims of wrongful termination, fraud, breach of contract, breach of duty of good faith and fair dealing, trademark infringement, unfair competition and dilution, breach of fiduciary relationships between franchisers and franchisees, tortious interference with business relationships, and claims under antitrust laws and the racketeering (RICO) statute. His victory in A.J. Temple Marble & Tile, Inc. v. Union Carbide Co., established the right of franchisees to sue under the New York Franchise Act regardless of disclaimers in the franchise agreement.
