Versions of s. 212(23)(b)

it can reasonably be considered that none of the main purposes of a transaction or event, or series of transactions or events, as a part of which the taxpayer pays or credits an amount as, on account or in lieu of payment of, or in satisfaction of, interest to a person or partnership in respect of the debt or other obligation is to avoid or reduce tax that would otherwise be payable under this Part by a non-resident person or partnership to whom the debt or other obligation is owed.
