Tax Prof Blog:  Guess?, Inc. co-founder Georges Marciano has lost his bid in Washington federal court for an order forcing the IRS to investigate his tax returns and liabilities.

Marciano had argued that the audit could reveal money owed to the government that he believes former employees mishandled. In dismissing the suit on Friday, U.S. District Court Judge Henry Kennedy Jr. noted that the property rights protected under the Fifth Amendment don’t guarantee anyone’s right to pay taxes.
