Antitrust litigation in Diamond Bar, California, involves claims that restrict competition, raise prices, or otherwise harm consumers and businesses. These actions fall under both federal and state law, often pursued in federal court in the Central District of California or in California state courts. The core federal statutes are the Sherman Act and the Clayton Act, which prohibit agreements and practices that restrain trade or monopolize markets.
Private lawsuits in antitrust matters can seek damages and, in some cases, injunctive relief. California also provides its own antitrust framework through the Cartwright Act and related provisions under the California Unfair Competition Law. Private plaintiffs may pursue treble damages and attorney’s fees for certain violations under federal law, depending on the statute and the claim.
