Sacramento class action attorneys work on both sides of large group lawsuits, from wage-and-hour cases against California employers to consumer fraud, data breach, product liability, and whistleblower claims that reach nationwide. A handful of local firms handle most of this work. On the plaintiff side, Kershaw Talley Barlow, Cutter Law, the Arnold Law Firm, Matern Law Group, and Mastagni Holstedt are the names that appear most often in significant recoveries. On the defense side, Downey Brand, Weintraub Tobin, and CDF Labor Law regularly represent the companies being sued. Which firm fits depends on the type of claim, the firm’s record with that specific kind of case, and how fees are structured.

Firms That Defend Class Actions
If your company has been served with a class or PAGA complaint, several Sacramento defense firms handle this work regularly.
Downey Brand LLP, founded in 1926 and headquartered on Capitol Mall, has a dedicated class action defense group with over 90 attorneys firmwide. The firm defended Sierra Pacific Industries in seven lawsuits stemming from the Moonlight Fire in Plumas County, where claimed damages exceeded $1 billion. Other results include defeating class certification for a shopping center owner (upheld on appeal), decertifying a class brought under California’s Unfair Competition Law for a regional food processor, and obtaining judgment on the pleadings in a nationwide warranty class action.15Downey Brand LLP. Class Action Defense

In April 2025, its shareholders obtained a published appellate opinion defending a private school against class fraud and unfair-business-practice claims.16Weintraub Tobin.

Sacramento-based partner Corey Cabral chairs the firm’s PAGA Litigation Practice Group and has represented employers in retail, transportation, and financial services. The firm reported settling a $17 million PAGA claim for a “fraction of exposure.”18CDF Labor Law. PAGA Litigation
What You’ll Pay
Most Sacramento plaintiff-side class action firms work on contingency. Clients pay nothing up front, and the attorneys recover a percentage of any settlement or judgment. In 2016, the California Supreme Court held in Laffitte v. Robert Half International Inc. that trial courts may calculate fees as a percentage of the total settlement fund rather than being limited to the lodestar method (reasonable hours multiplied by a reasonable hourly rate).19Sheppard Mullin. California Supreme Court Approves Attorney Fee Awards Calculated Based Upon Percentage Class Action Common Fund The court in Laffitte approved fees of one-third of a $19 million employment class settlement. Judges may cross-check a percentage fee against the lodestar to test reasonableness, but they are not required to.
Federal courts in California typically demand detailed lodestar information even when fees are requested as a percentage. In the Northern District, counsel must file declarations breaking down hours by activity and biller, and after distribution they must file a post-distribution accounting showing the final fee as a percentage and the resulting lodestar multiplier.20U.S. District Court, Northern District of California. Procedural Guidance Class Action Settlements The practical effect for class members is that a judge scrutinizes the fee before any money moves.
What to Look For When Hiring
Experience with your specific type of claim matters more than a general list of accolades. A firm that routinely handles wage-and-hour class actions moves through certification, discovery, and settlement approval faster than a generalist doing its first one. A firm that has litigated defective medical devices already knows the expert witnesses and the science. Match the firm to the case.
Resources matter too. Class actions are expensive, and they can run for years before resolution. Wedding v. CalPERS took a decade. A firm needs the financial stability to front expert costs, discovery, and trial preparation without passing those costs back to clients.
Look at completed cases, not just headline settlement figures. Has the firm actually obtained class certification and taken cases through final approval? Certification is where many class actions die, and a firm that regularly wins that fight is doing something the defense bar respects.
Communication style is the last piece. Class litigation involves long stretches of procedural work where nothing visible happens for months. A firm that provides regular updates and explains developments in plain language is worth more than one that goes silent between hearings.
A Note on PAGA Claims
Not every representative employment case is a class action. The Private Attorneys General Act, enacted in 2004, lets a single California worker sue on behalf of all affected employees to enforce the Labor Code and recover civil penalties. PAGA claims often ride alongside wage-and-hour class actions but follow different procedural rules, and they do not require class certification.18CDF Labor Law. PAGA Litigation
In July 2024, Governor Newsom signed AB 2288 and SB 92, the most significant PAGA overhaul in the statute’s twenty-year history. The reforms apply to actions filed on or after June 19, 2024. The worker share of penalties rose from 25% to 35%, with the state receiving 65%. Plaintiffs must now have personally experienced each alleged violation to have standing, and courts gained authority to limit the scope of claims at trial and to consolidate overlapping PAGA actions against the same employer. The reforms also cap penalties for employers that take proactive compliance steps: an employer that shows “all reasonable steps” before receiving a PAGA notice can cap penalties at 15% of the total, and one that acts within 60 days of notice faces a 30% cap.21Senate Judiciary Committee. AB 2288 Analysis Courts can now also grant injunctive relief ordering workplace changes, which the original statute did not permit. If your matter involves a PAGA notice, ask any prospective firm how it handles the new early evaluation conference and the cure provisions, because those steps can end a case before discovery even opens.
