“Where, at any time during the period for which an award of a tax credit is made to a person or persons, [H.M.R.C] have reasonable grounds for believing…that…(b) [she] has…ceased to be… entitled to the tax credit for the period, [H.M.R.C] may decide to amend or terminate the award.”
“Where [HMRC]…(b) decide under section 16 to terminate an award of a tax credit made on a claim, (subject to any appeal) any entitlement, or subsequent entitlement, to the tax credit for any part of the same tax year is dependent on the making of a new claim.”
“What happens to an appeal once a decision is given under section 18? “42…The Tax Credits Act 2002 makes no provision for the effect of a section 16 decision after a section 18 decision has been made. However, section 18(11) provides that the decision under that section is conclusive, which carries with it the implication that the section 16 decision is no longer of any force or effect. That is lapsing in all but name. The disadvantage of this approach is that it is automatic. In most cases that would not matter, but there may be cases in which it would be appropriate to proceed with the appeal despite the fact that it had been overtaken by the section 18 decision. 43. Another analysis is that the tribunal should treat the appeal as raising only hypothetical issues. Courts decline to deal with such issues in public law cases. The appeal tribunal could do the same, simply declaring that the only issues raised are hypothetical and declining to decide them. The advantage of this approach over the lapsing of a decision or an appeal is that it gives the tribunal a discretion. The courts are prepared to decide hypothetical issues in public law cases if ‘there is a good reason in the public interest for doing so’, as Lord Slynn explained in R v Secretary of State for the Home Department, ex parte Salem [1999] 1 A.C. 450 at 457. This would allow a tribunal to proceed with an appeal against a decision under section 16 (or for that matter under section 14 or 15) if, for example, it raised an issue of general importance, such as the scope of an appeal under that section.”
