The Law Offices of M. Brian McMahon

The Law Office of M. Brian McMahon focuses on complex civil litigation specializing in state and federal antitrust law, unfair competition, oil and gas law, environmental law, including the CERCLA and the HSAA, and appellate practice.

The Firm was one of a team of six law firms that brought antirust lawsuits against El Paso Natural Gas Company, Sempra Energy, SoCal Gas and SDG&E on behalf of natural gas and electricity customers in California arising out of the California Energy Crisis. The Firm represented the City of Long Beach and the Long Beach natural gas ratepayers and recovered settlements of over $25 million dollars. The combined lawsuits recovered more than $3.5 billion for Californians and insured that the defendants will make significant structural changes that will prevent future energy crises.

The MBM Law Offices recently obtained a summary judgment dismissing all claims in a contribution action brought under CERCLA and HSAA.

As co-lead counsel in a Sherman Act antitrust case against seven major oil companies, the Firm achieved settlements worth over $300 million for its client. The case arose out of a price fixing conspiracy to underprice crude oil.

The Firm successfully obtained settlements from major oil companies for millions of dollars for the State of New Mexico for underpayments of that State’s crude oil.

In a case seeking restitution of alleged overpayments for crude oil sold by a client, the Firm obtained a reversal of the lower court’s judgment in the Federal Circuit.

The Firm provided assistance to a Federal Interagency Task Force investigating underpayments of federal crude oil royalties by oil companies. In addition, the Firm assisted the Minerals Management Service (MMS) of the United States Department of Interior in recovering unpaid crude oil royalties.

Successfully representing the State of California and coordinating the efforts of several states, the Firm convinced the United States Department of Interior to change its valuation regulations for federal crude oil. In this effort, he and his associates provided written and oral testimony at MMS hearings and met with MMS and Interior Department officials. The Firm also provided written comments to drafts of new MMS regulations. The efforts proved successful, as the Department of Interior changed its regulations to insure that oil companies pay market value for federal royalty crude oil.
