A federal judge in Texas dismissed Exxon Mobil's lawsuit against activist investor Arjuna Capital over a shareholder proposal to reduce greenhouse gas emissions. Judge Mark T. Pittman ruled the case moot after Arjuna Capital withdrew the proposal and promised not to submit similar proposals in the future. This lawsuit, filed in January, had raised concerns among activists and investors about stifling shareholder debate and bypassing SEC regulations. Exxon continued the suit despite the withdrawal, fearing future similar actions. The court's decision underscores ongoing tensions between corporate actions and shareholder activism on climate issues. The dismissal allows Exxon to refile the case if similar proposals arise again.
