Remember the insider trading scandals of the 1980's, when wall street hot shots such as Michael Milken and Ivan Boesky made millions, and lost those millions after they were jailed on insider trading charges?

The high court will hear the case of former Minneapolis attorney James O'Hagan whose 57-count conviction on securities fraud was overturned by a federal appeals court.
