The Securities and Exchange Commission (SEC) has recently achieved several legal victories, reinforcing its regulatory stance. A federal appeals court ruled in favor of the SEC in a split decision, allowing the agency to rescind parts of Trump-era regulations on proxy advisers. This decision was upheld by the 6th Circuit, confirming the SEC's authority in this matter. The SEC brushed aside a last-minute effort by firms including EY and PwC to halt the new governance rules. Additionally, the SEC has taken a broad view of the anti-whistleblower rule, targeting investment advisers and broker-dealers. The agency also secured a win in a 'shadow trading' case, with the court upholding its stance.
