For the purposes of the provisions of TMA 1970 relating to appeals, the giving of notice by an officer of Revenue and Customs under section 234(3)(b) is taken to be a decision disallowing a claim by the issuing company.

If any issue has been determined on an appeal brought by virtue of paragraph 1A(6) of Schedule 5B to TCGA 1992 (appeal against notice that shares never have been, or have ceased to be, eligible shares), the determination is conclusive for the purposes of any appeal brought by virtue of subsection (1) on which that issue arises.
