It overturned a lower-court decision favoring the insurance giant's former CEO.
The ruling today by the US Court of Appeals for the Federal Circuit said a company controlled by ex-AIG chief Maurice Greenberg didn't have a legal right to pursue its claim against the government.
Greenberg had alleged that the USD 85 billion bailout of the teetering AIG in September 2008 violated the Constitution's Fifth Amendment by taking control of the company without "just compensation."
The unusual case raised the issue of limits on the government's power in responding to financial catastrophe. The new ruling handed a victory to the government.
