“Our conclusion on this point, therefore, is that s 29(5) does not require the hypothetical officer to be given the characteristics of an officer of general competence, knowledge or skill only. The officer must be assumed to have such level of knowledge and understanding that would reasonably be expected in an officer considering the particular information provided by the taxpayer. Whilst leaving open the exceptional case where the complexity of the law itself might lead to a conclusion that an officer could not reasonably be expected to be aware of an insufficiency, the test should not be constrained by reference to any perceived lack of specialist knowledge in any section of HMRC officers. What is reasonable for an officer to be aware of will depend on a range of factors affecting the adequacy of the information made available, including complexity. But reasonableness falls to be tested, not by reference to a living embodiment of the hypothetical officer, with assumed characteristics at a typical or average level, but by reference to the circumstances of the particular case”
