The suit alleged that Alliantgroup and an architectural firm hired by the universities, WHR Architects, Inc., conspired to reap more than $1.6 million in unauthorized tax benefits from the 2007 construction of the $5.5 million University of Houston Center, and the construction of an MD Anderson parking garage and a UT-Health Science Center project.
