The taxpayers offered "10-8" insurance plans to their customers, which generated exempt income and deductible interest. Under a 10-8 plan, the customer borrows money at 10% tax-deductible interest, and uses the borrowed amount to obtain an investment vehicle that returns 8% tax-exempt interest. After the Minister obtained authorizations from the Federal Court under s. 231.2(3) requiring the taxpayers to disclose customer lists, the taxpayers successfully applied under s. 231.2(6) to have those prior authorizations cancelled. The Minister had withheld significant information on the original application, including that CRA was deliberately engaging in an "audit blitz" so as to have a chilling effect on the 10-8 plans, notwithstanding that they were acknowledged to technically work.
The Court affirmed the cancellation of the authorizations. In response to a submission that a judge reviewing such authorization under s. 231.2(6) may only consider specifically whether the conditions in s. 231.2(3)(a) and (b) are satisfied, Stratas J.A. stated that the existence of judicial discretion is essential to the constitutional validity of an authorization in the first place under s. 231.2(3) (para. 23), that the "review under subsection 231.2(6) must include a discretionary element and is not limited to verifying that the two statutory preconditions are met" (para. 27), and that the alternative would render the Court "powerless" to address an abuse of process (para. 28): such as the withholding of relevant information - for example "the Minister could misinform the judge about the inconvenience and cost to persons who will be subject to the authorization" (para. 30); or even "bald lies" (para. 29).
Since Canada (Human Rights Commission) v. Canadian Liberty Net, [1998] 1 S.C.R. 626 at paras. 35-38, the Federal Courts have had "plenary powers" analogous to the inherent powers of a provincial superior court (para. 35), which include the power to address abuse of process.
