Sections 172 –Appealable decisions
199.Section 172 gives a person to whom an appealable decision applies a right to ask WRA to review a decision and a right to make an appeal to the tribunal and sets out which decisions of WRA are to be classed as appealable decisions. Subsection (3) lists those decisions which are carved out of subsection (2) so as to make them non appealable (including, a decision to issue a notice of enquiry (but the conclusions of an enquiry are appealable) and a decision to issue a taxpayer notice, or include a particular requirement in such a notice (which must have the prior approval of the tribunal). Subsection (4) removes the right to request a review of a decision to issue an information notice where the tribunal has already approved it (this avoids WRA being able to change a decision of the tribunal). Subsection (5) limits the grounds on which a review or appeal can be based in relation to information notices so that the grounds of appeal are consistent with the grounds on which such a notice may be issued in the first place. The Welsh Ministers have a regulation making power at subsection (7) to add, vary or remove a decision from either of the lists of appealable or non-appealable decisions in subsections (2) and (3) or to make provision about the grounds on which an appeal or review of a decision may be based.
