A D.C. judge has ruled that the law firm Crowell & Moring cannot force its Washington, D.C., landlord to refund $30 million in rent paid during the COVID-19 pandemic. The firm had argued that it was entitled to refunds for rent payments made between April 2020 and May 2021, a period when most of its lawyers were working from home. The decision underscores the challenges businesses face in recouping pandemic-related expenses.
