The US Department of Justice has argued that Michigan’s antitrust lawsuit accusing several of the world’s largest oil companies of conspiring to suppress competition from renewable energy and electric vehicles is unlikely to succeed, adding the federal government’s view to a closely watched climate-related competition case.

    According to Bloomberg Law, the Justice Department said in a court filing that Michigan’s complaint does not sufficiently establish the elements required to prove an antitrust violation. Bloomberg Law reported that the department believes the state failed to allege the type of agreement or anticompetitive conduct necessary to support its claims.

    The lawsuit, filed by Michigan Attorney General Dana Nessel, names Exxon Mobil, Chevron, Shell, BP and the American Petroleum Institute. Michigan alleges the defendants coordinated over decades to restrain competition from renewable energy technologies and electric vehicles, limiting consumer choice and slowing the adoption of alternative energy sources.

    The antitrust allegations distinguish Michigan’s case from many other climate lawsuits brought by states and local governments. Rather than seeking damages primarily for climate-related harms or alleged deception about fossil fuels, the complaint argues the companies violated federal and state competition laws by acting together to preserve their market position and impede emerging competitors.

    According to Bloomberg Law, the Justice Department argued that allegations of parallel industry conduct alone are not enough under established antitrust law. The filing reportedly states that Michigan’s complaint does not plausibly allege an unlawful agreement or the type of concerted action required under federal competition standards.

    The defendants have denied wrongdoing. Industry representatives have argued that the lawsuit is legally flawed and that energy policy should be shaped through legislation and regulation rather than litigation. Chevron has called the claims baseless, while the American Petroleum Institute has said similar lawsuits improperly seek to regulate energy policy through the courts.

    The case is notable because it applies antitrust law to claims involving the transition to alternative energy. Unlike many climate-related lawsuits against fossil fuel companies, Michigan’s complaint alleges competition law violations based on purported coordination to limit competition from renewable energy and electric vehicles.

    Michigan’s lawsuit is one of several legal actions nationwide targeting fossil fuel companies over alleged conduct related to climate change. While many of those cases rely on consumer protection or public nuisance claims, Michigan’s case centers on alleged anticompetitive conduct under federal and state antitrust laws.
