(3)Subsection (2) shall not prevent a tax-varying resolution relating to any year of assessment from being passed and having effect where—
(a)a determination by the Parliament of the United Kingdom of the rate to be the basic rate for that year is made after, or less than a month before, the beginning of that year,
(b)that determination is not confined to the passing of the enactment by which a determination of the same rate by a PCTA resolution is ratified, and
(c)the tax-varying resolution is passed within the period of one month beginning with the day of the making by the Parliament of the United Kingdom of its determination.
(4)Where, in a case to which subsection (3) applies, a tax-varying resolution is passed after the beginning of the year of assessment to which it relates—

(b)all such payments, repayments, deductions and other adjustments shall be made as are required to restore the position to what it would have been if the resolution had been passed before the beginning of that year.
(5)Standing orders shall ensure that only a member of the Scottish Executive may move a motion for a tax-varying resolution.
