“ The test of whether or not there is a reasonable excuse is an objective one. In my judgment it is an objective test in this sense. One must ask oneself: was what the taxpayer did a reasonable thing for a responsible trader conscious of and intending to comply with his obligations regarding tax, but having the experience and other relevant attributes of the taxpayer and placed in the situation that the taxpayer found himself at the relevant time, a reasonable thing to do?”
“ The test of reasonable excuse involves the application of an impersonal, and objective, legal standard to a particular set of facts and circumstances. The test is to determine what a reasonable taxpayer in the position of the taxpayer would have done in those circumstances, and by reference to that test to determine whether the conduct of the taxpayer can be regarded as conforming to that standard.”
