The Marc Rich Case: A Primer (Time.com)

What was Marc Rich's alleged crime?

In 1983, Rich was indicted in federal court of evading more than $48 million in taxes. He was also charged with 51 counts of tax fraud and with running illegal oil deals with Iran during the hostage crisis.

So does the pardon mean that if Rich leaves Switzerland (where he's been living for 17 years and seems quite happy to stay) and comes back to the U.S., that he won't face any legal proceedings at all?

Possibly. He's free of any criminal charges in connection with the case, but Rich can still be charged in civil court on, say, tax evasion charges. In fact, when Clinton finally signed off on Rich's pardon, the President stipulated that Rich waive the statute of limitations normally placed on as yet unspecified civil charges.
