The influential advisory firm controlled by the $500 billion industry super fund sector would be kneecapped under a push by Treasurer Josh Frydenberg to regulate the way institutional shareholders vote on how companies deal with environmental, social and governance issues.

The proposed measures include forcing proxy advisers to give the companies they are reviewing a week’s notice of how they are recommending shareholders should vote and the research on which it is based. Firms would also have to give clients access to the company’s response.
