Being dubbed the most obnoxious lawyer in the nation’s largest city is an impressive feat.

Now Heller is back in the headlines, charged along with six other defendants for collectively hiding $100 million from the IRS.

The charges are the latest salvo in the long-running tax battle between the U.S. Department of Justice and the IRS against Swiss banking giant UBS.
