Taxpayer (TP) has a deduction for 2014 that is supported and justified by a case decided in 1985. Which of the following statements is correct?
a. The case cannot be used by TP as support for TP's deduction because the case was decided one year before TRA of 1986.
b. If the case involves a statute that is still valid in 2014, but the IRS nonacquiesced to the case, then TP is legally allowed to use the case as support for TP's deduction but the TP will probably have to go to trial to resolve the deductibility of the deduction.
c. None of the other choices are correct.
d. If the case involves a statute that is still valid in 2014, but the IRS nonacquiesced to the case, then TP is legally prohibited from using the case as support for TP's deduction.
