A debtor in a bankruptcy case is fighting back against an unusual maneuver that would allow trustees to boost their clawback authority in cases that involve unpaid federal taxes.

Construction executive Donald Kipnis, whose defunct Miller & Solomon General Contractors Inc. built the $150 million Downtown Dadeland project, filed a Chapter 11 bankruptcy petition in 2014 and later converted to Chapter 7. The IRS filed a proof of claim for more than $1.91 million.
