M.C. Sungaila has successfully briefed and argued appeals raising cutting-edge and core business issues statewide as well as nationally and internationally. Clients appreciate her “clear, concise, and persuasive” manner, laud her as a “great strategic thinker who plays five or six moves ahead,” and call on her to craft winning approaches to emerging legal issues across multiple cases and jurisdictions. Clients also value M.C.’s strategic approach during pretrial and trial consultations in cases where an appeal by either side appears inevitable or a “key case” outcome might impact a whole series of cases for a client.
Over the past decade, M.C. has been the primary architect of winning arguments to screen and exclude unfounded expert testimony in California courts—a standard which previously remained undeveloped in the state. Using her signature proactive, “big picture” approach, M.C. helped secure victories in every significant expert testimony case decided by California appellate courts in recent years.
Fortune 500 companies and leading international human rights organizations also have relied on M.C. to help define the scope of the duty to warn sophisticated users of product hazards, overturn multimillion dollar judgments, limit the reach of medical monitoring claims, clarify the standards for interstate enforcement of noncompete agreements, and secure important rights for women worldwide.
M.C. has received multiple awards and recognition for her work. Repeatedly named one of California's Top Women Litigators by the Los Angeles and San Francisco Daily Journals, she is also one of a select group of women to receive the Frances E. Willard Award, Alpha Phi International Fraternity’s highest alumnae honor for professional achievement on a national and international level. In 2011, M.C. was the only lawyer named in OC Metro business magazine's annual list of the "Top 20 Women to Watch in Orange County."
Also in 2011, her innovative amicus brief in the closely-watched U.S. Supreme Court class action Wal-Mart v Dukes — one among fifteen different briefs filed in support of Wal-Mart by a number of veteran Supreme Court litigators — earned her the title “Appellate Lawyer of the Week” from the National Law Journal. M.C. is also listed in the Best Lawyers in America and the Top 50 Southern California Female Super Lawyers.
In addition, M.C.’s various articles on effective amicus briefing, appellate brief writing, and gender issues have been cited in over 35 law review articles, treatises and blogs, and appear as required reading on law school course syllabi throughout North America. Her expert commentary has appeared in a variety of publications ranging from the ABA Journal and National Law Journal to the Los Angeles Times and USA Today.
