Robin Greenhouse was interviewed in the June 1, 2009, Tax Analysts Tax Notes concerning key tax law issues. Ms. Greenhouse stated that the U.S. tax system has become more adversarial in the past 10 years. IRS attorneys are routinely involved throughout the examination, crafting information document requests and interviewing witnesses. In response, the taxpayers involve their lawyers at earlier stages. She added, "While this may be good for tax controversy lawyers, it tends to lead to more disputes over privilege claims."
