Praised as “a master in the courtroom,” “outstanding in his trial capabilities,” and a client’s “secret weapon,” Mr. Kaba has stacked up an enviable record of trial and appellate victories in courts across the country. Mr. Kaba’s trial record makes him a go-to trial lawyer and trusted advisor to his clients, earning top rankings from Chambers and bolstering his standing as a “powerhouse” lawyer and “trial specialist” in multiple national rankings, including one of the best nationwide Trial Lawyers by Chambers and one of the “Top 100 Trial Lawyers in America” (the youngest lawyer in the country on the list). He is also consistently recognized as one of the “Top 20 Trial Lawyers in California” by Benchmark Litigation.

Mr. Kaba is a fellow of the International Academy of Trial Lawyers, a group of “truly elite trial lawyers who have achieved a career of excellence through demonstrated skill and ability in jury trials.” This is an invitation only organization limited to 500 active trial lawyers from the United States.

From a variety of Fortune 500 companies to entrepreneurs and high-profile individuals, Mr. Kaba develops creative and disruptive strategies to solve business’ unique objectives in a broad array of general complex civil litigation, including commercial disputes, securities, trade secrets, entertainment, and intellectual property litigation.

As touted by Chambers, “there’s nobody quicker or more consistently on the money when complex judgment calls need to be made,” with clients adding “he is innovative, smart and able to see problems from various perspectives. His oral advocacy skills are second to none.” “He has a remarkable ability to hone in on the most salient issues immediately.” As Chambers succinctly put it, Mr. Kaba is “an incredibly strong lawyer,” “he tries a lot of cases and wins, which is what it’s all about.”

In addition to his litigation practice, Mr. Kaba dedicates considerable time to pro bono work focusing on access to justice and social issues. Among his pro bono achievements: He obtained a preliminary injunction for Freedom for Immigrants (FFI) in an important, closely watched, First Amendment case, ordering U.S. Immigration & Customs Enforcement to restore FFI’s National Immigration Detention Hotline. (See media highlights here). He represented the Council for American-Islamic Relations in its efforts to support a San Diego school district regulation that was designed to protect Muslim students who are particularly at risk of being bullied. (See media highlights here). He represented Equality California in challenging the constitutionality of California’s ban on same-sex marriage in the United States Supreme Court. For several years, he represented various women’s rights groups in cases challenging the constitutionality of the Defense of Marriage Act (DOMA) and state bans on same-sex marriage.
