If it appears to the Board—
a
that any amount of APRT credit which has been set off against a participator's assessed liability to petroleum revenue tax for any chargeable period ought not to have been so set off, or that the amount so set off has become excessive, or
b
that, disregarding any liability to or credit for APRT, a participator is entitled to a repayment of petroleum revenue tax for any chargeable period,
then, for the purpose of securing that the liabilities of the participator to petroleum revenue tax and APRT (including interest on unpaid tax) for the chargeable period in question are what they ought to have been, the Board may make such assessments to, and shall make such repayments of, petroleum revenue tax and APRT as in their judgment are necessry in the circumstances.
