12(1)This paragraph applies where HMRC are required to undertake a review under paragraph 11.U.K.
(2)The nature and extent of the review are to be such as appear appropriate to HMRC in the circumstances.
(3)HMRC must, in particular, have regard to steps taken before the beginning of the review—
(a)by HMRC in reaching the decision, and
(b)by any person in seeking to resolve disagreement about the decision.
(4)The review must take account of any representations made by the individual at a stage which gives HMRC a reasonable opportunity to consider them.
(5)But it is not open to the individual to challenge the existence or amount of any tax liability of a company to which the joint liability notice in question relates.
(6)At the conclusion of the review—
(a)HMRC must set aside the notice to which the review relates if it appears to them that—
(i)any of the relevant conditions were not met when the notice was given, or
(ii)it is not necessary for the protection of the revenue for the notice to continue to have effect;
(b)HMRC must set aside the notice or vary an amount specified under paragraph 2(9)(a), 3(11)(c) or 5(8)(a), or (as the case may be) paragraph 2(10) or 5(9), if it appears to HMRC that the amount specified is incorrect;
(c)otherwise, HMRC must uphold the notice.
(7)HMRC must give the individual notice of the conclusions of the review and their reasoning—
(a)within the period of 45 days beginning with the relevant date, or
(b)within any other period that HMRC and the individual may agree.
(8)In sub-paragraph (7) “relevant date” means—
(a)the date on which HMRC received the individual's notification accepting the offer of a review (in a case falling within paragraph 11(1)), or
(b)the date on which HMRC decided to undertake the review (in a case falling within paragraph 11(4)).
(9)Where HMRC do not give notice of the conclusions within the time period specified in sub-paragraph (7)—
(a)the notice to which the review relates is treated as upheld, and
(b)HMRC must notify the individual accordingly.
(10)Where a joint liability notice is set aside under sub-paragraph (6)(a)(ii), the setting aside of the notice does not give the individual a right to recover any amount that the individual has already paid to HMRC in response to the notice.
