California plaintiffs firm Engstrom, Lipscomb & Lack owes more than $1 million in federal corporate taxes and penalties relating to business expenses from two personal aircraft, according to a federal appeals court’s ruling this week.

The U.S. Court of Appeals for the Ninth Circuit on Wednesday upheld a finding by a U.S. Tax Court judge that Los Angeles-based Engstrom owed $1.12 million after claiming unsubstantiated travel expense deductions relating to 119 flights taken from 2008 to 2010.
