An appeals court in Chicago says a lower court in Indiana was right to refuse to permit a couple to rescind their guilty pleas in a tax case on grounds their prosecution caused them severe stress.

The 7th U.S. Circuit Court of Appeals said stress was common to anyone facing prosecution and wasn't sufficient reason to take back pleas. It added that neither George nor Barbara Gasich could claim they were under some "Napoleonic delusions" when they chose to plead guilty.

The Chicago Daily Law Bulletin reports the Gasiches were indicted in 2014 for making fraudulent claims. Prosecutors said they'd asked for $475,000 in refunds when they owed the IRS far more than that.

The Gasiches were formerly from St. John, Indiana, but lived in Florida when they were arrested.
