Sec. 5. (a) This section applies with respect to judicial review of final determinations of the Indiana board of tax review.
(b) The tax court may receive evidence in addition to that contained in the record of the determination of the Indiana board of tax review only if the evidence relates to the validity of the determination at the time it was taken and is needed to decide disputed issues regarding one (1) or both of the following:
(1) Improper constitution as a decision making body or grounds for disqualification of those taking the agency action.
(2) Unlawfulness of procedure or decision making process.
This subsection applies only if the additional evidence could not, by due diligence, have been discovered and raised in the administrative proceeding giving rise to a proceeding for judicial review.
(c) The tax court may remand a matter to the Indiana board of tax review before final disposition of a petition for review with directions that the Indiana board of tax review conduct further factfinding or that the Indiana board of tax review prepare an adequate record, if:
(1) the Indiana board of tax review failed to prepare or preserve an adequate record;
(2) the Indiana board of tax review improperly excluded or omitted evidence from the record; or
(3) a relevant law changed after the action of the Indiana board of tax review and the tax court determines that the new provision of law may control the outcome.
(d) This subsection applies if the record for a judicial review prepared under IC 6-1.1-15-6 contains an inadequate record of a site inspection. Rather than remand a matter under subsection (c), the tax court may take additional evidence not contained in the record relating only to observations and other evidence collected during a site inspection conducted by a hearing officer or other employee of the Indiana board of tax review. The evidence may include the testimony of a hearing officer only for purposes of verifying or rebutting evidence regarding the site inspection that is already contained in the record.
