(a)any amendment of a self-assessment under paragraph 16 (amendment by HMRC during enquiry to prevent loss of tax),
(b)any conclusion stated or amendment made by a closure notice, or
(c)any assessment to tax which is not a self-assessment.
(2)An appeal may also be brought against a determination by an officer of Revenue and Customs of a claim for a reduction under paragraph 7, but only on the ground that it was not open to the officer to consider the reduction determined by the officer (including a determination not to make any reduction) was just and reasonable.
