Something’s rotten in D.C.’s Office of the Chief Financial Officer, and it’s up to the D.C. Council to get to the bottom of it.

In August, the Washington Post first reported that the Office of Tax and Revenue under CFO Natwar Gandhi had secretly lowered contested commercial real estate assessments for some of the city’s wealthiest developers by $2.6 billion instead of going to court. Last week, the Post reported that tax cases filed in D.C. Superior Court but settled before trial amounted to an additional $1.2 billion, for a total of $3.8 billion in reduced assessments.
