Step-by-step explanation:
In United States v. O'Hagan, the Supreme Court ruled that a lawyer who traded on insider information breached a fiduciary duty to the source of the information, which aligns with the concept often referred to as Insider Trading. This ruling emphasized the importance of upholding legal and ethical standards within financial markets by affirming that individuals with access to non-public information must not use it for personal gain. This upholds the integrity of the markets and aims to preserve a fair playing field for all investors.
The Court's decision can be best characterized as aligning with a social contract approach. By enforcing laws against insider trading, the Supreme Court helps maintain investor trust in the market, ensuring that no one has an unfair advantage through access to confidential information. This reflects a commitment to equal opportunity and the protection of market integrity, hence providing a foundation for a stable and fair financial environment where investors' interests are respected.
