“For many taxpayers the new time limits will not come into effect until1 April 2012 .”
“The quote made in the appeal documents “For many taxpayers the new time limits will not come into effect until1 April 2012 ” refers to taxpayers who are outside of the Self Assessment regime i.e. taxpayers whose tax affairs are dealt with under PAYE. Mr Durkin’s tax affairs are dealt with within the Self Assessment regime and therefore the new time limits applied from1 April 2010 .”
“ The discretionary power in question is that conferred on the Revenue to extend the time stipulated in subsection (3). Mr Rabinder Singh referred me to a judgment of Arden J in Kelsall (H M Inspector of Taxes) Investment Chartwork Ltd 65 TC 750. The case did not involve the same discretion as in the present case but did raise the question whether the exercise by the Revenue of a statutory discretion could be reviewed and upset by the General Commissioners on an appeal. Arden J held that it could not. She referred to the decision of the House of Lords in Customs and Excise Commissioners J H Corbitt (Numismatists) Ltd[1980] STC 231 in which Lord Lane, with whose speech the majority of the House agreed, approved the following passage from the judgment of Neill J: "Once it is conceded, as I think rightly, that the commissioners are empowered, subject to the control of the Treasury, to lay down the conditions in a general notice such as Notice No.712 in such a form as they consider proper and that that power is not subject to appeal, it seems to me impossible to contend that the discretion given by the final words of article 3(5) 'or may recognise as sufficient for those purposes' is a different kind of discretion which is subject to appeal." Arden J referred also to Slater Richardson 53 TC 155 in which Oliver J had said: "There is nothing in those words, I think, which can possibly enable the General Commissioners to discharge an assessment on the ground that the circumstances were such that the Collector of Taxes ought to have exercised a discretion which is placed upon him to remit tax which is clearly payable under the provisions of the section." Following the statements of principle expressed in those cases, Arden J held that the Commissioners on an appeal against a decision of the Revenue did not have power to substitute their own discretion for the statutory discretion to be exercised by the Revenue. In my judgment, the same applies to the present case. Subsection (3) of s 152 clearly gives power to the Revenue at its discretion to allow an extended period within which the acquisition of the new assets may take place. No criteria are expressed in the subsection as to when the power should or should not be exercised. The matter is left entirely to the discretion of the Revenue. The exercise of that power by the Revenue would be susceptible to challenge by judicial review on the grounds of unreasonableness or any other suitable ground, but it is not a power that can be exercised by the General Commissioners. In my judgment, the decision of the Revenue as to whether or how to exercise its subsection (3) discretion is not reviewable by the General Commissioners on an appeal. It follows that, in my view, it was not open to the General Commissioners to extend the three-year period within which the new assets had to be acquired, or expenditure on improvements had to be incurred, in order to allow a claim for rollover relief to be made.”
