The U.S. Supreme Court has denied Starr International Co. Inc.'s request for a review of the appeals court ruling that it lacked the standing to sue the U.S. government over the bailout of American International Group Inc., Bloomberg News reported.

The lawsuit was brought by former AIG CEO and current head of Starr Cos. M.R. "Hank" Greenberg.

Starr's lawyer, David Boies, expressed disappointment at the Supreme Court's decision, claiming that the government is unfairly treating AIG's shareholders, according to the report.

The lawsuit sought compensation for the $85 billion bailout of AIG during the financial crisis that handed the government 80% of the company's equity.
