The taxpayer argued that his assessment should be vacated because the Minister failed to act with all due dispatch to reconsider his assessment. Hugessen JA dismissed the taxpayer's appeal. Ginsberg, decided a week before, establishes that this is not a basis to vacate an assessment. Moreover, the taxpayer's right to appeal under s. 169(b) (i.e. where the Minister has taken 90 days or more to respond to a notice of objection) would be nonsensical if the effect of the Minister's failure were already to vacate the assessment.
