A new lawsuit filed by Florida Attorney General James Uthmeier has escalated political tensions around ESG investing in the United States, targeting proxy advisory giants Glass Lewis and Institutional Shareholder Services. The complaint accuses the firms of misleading clients, abusing dominance in the shareholder voting market and advancing ideological objectives through their voting recommendation frameworks. The case marks another significant clash between state officials and the companies that shape shareholder governance in corporate America.

A High-Profile Challenge to Proxy Advisors’ Role in Corporate Governance

Glass Lewis and ISS collectively control the vast majority of the proxy advisory market, supplying institutional investors with analysis and recommendations on how to vote on shareholder proposals and board elections. State pension funds, asset managers and private investors rely heavily on their guidance during annual meeting seasons. Over the past year, proxy advisors have become a central target in the broader anti-ESG movement among some U.S. state officials. The Florida complaint follows several investigations and political statements accusing proxy firms of promoting agendas tied to diversity, climate change and other governance reforms. Texas Attorney General Ken Paxton launched a similar investigation in September, alleging that the advisory firms were steering votes toward political objectives rather than fiduciary priorities. The latest lawsuit claims that ISS and Glass Lewis have used their influence to pressure companies through recommendations that penalize boards for policies related to climate oversight, diversity expectations and social issues. Florida officials argue that such recommendations distort corporate decision making and undermine the financial interests of retirees whose pensions depend on shareholder returns.

Arguments Put Forward by Florida’s Attorney General

Uthmeier said that the state intends to prevent what it views as backdoor policymaking carried out through private firms that are not subject to public accountability mechanisms. He described the proxy advisors as using their market position to apply national ESG expectations onto companies and investors who did not choose to pursue those priorities. The lawsuit asserts that the firms misrepresent their independence by advertising their recommendations as financially grounded while allegedly embedding political judgments into their voting frameworks. Florida further argues that the firms participate in industry coalitions and associations that promote climate and social disclosure standards, which the state portrays as evidence of collusion and ideological alignment. The complaint also claims that the similarity of the firms’ analytical tools and voting recommendations limits meaningful competition in the proxy advisory landscape. By presenting aligned evaluations on key ESG topics, Florida argues that the advisors shape corporate policy in a way that exceeds their proper role in financial markets.

The Broader Political and Regulatory Context

Proxy advisors have long operated at the intersection of investor fiduciary duties and corporate governance expectations. Their influence has increased in recent years as institutional investors have taken stronger positions on climate risk, workforce diversity and political spending disclosure. These developments have prompted calls for closer scrutiny from regulators who believe the firms should be subject to heightened transparency and accountability standards. The Securities and Exchange Commission has signaled an interest in reviewing the role of proxy advisors in shareholder activism, with Commissioners highlighting concerns about the growing volume of sustainability related proposals. The broader policy debate reflects the unresolved question of how investor expectations around climate and social risk should be balanced with political concerns about corporate neutrality. The Florida lawsuit arrives at a time when federal climate disclosure rules face uncertainty, leaving states as the primary battleground for ESG policy disputes. As some states push aggressively against ESG considerations, others have adopted their own climate and human rights requirements, creating an increasingly fragmented regulatory landscape for publicly traded companies.

Industry Response and Next Steps in the Case

Glass Lewis has dismissed the allegations as unfounded, noting that their clients are sophisticated institutional investors who assess recommendations independently. The firm said it is prepared to defend itself through the legal process and emphasized that it provides analytical tools rather than binding voting instructions. ISS has not publicly commented, though it has previously argued that attacks on proxy advisors are politically driven and threaten investors’ ability to evaluate corporate risk effectively. The lawsuit is expected to reignite debate around whether proxy advice constitutes subjective political activity or a core element of fiduciary analysis. It also raises the question of how far U.S. states can go in policing the activities of private firms operating across multiple jurisdictions. For companies and institutional investors, the case underscores the growing pressure to navigate evolving expectations around ESG disclosures and corporate governance practices while responding to political scrutiny over how shareholder rights are exercised.
