(b) in the case of an appellant who is an individual, his or her personal public service number (within the meaning of section 262 of the Social Welfare Consolidation Act 2005) or, in the case of any other person, whichever of the numbers in respect of the person specified in paragraphs (b) and (c) of the definition of “tax reference number” in section 885(1) is appropriate,
(c) the appealable matter in respect of which the appeal is being made,

(e) any other matters that, for the time being, are stipulated by the Appeal Commissioners for the purposes of this subsection.
