The Queen v. TransGas Ltd., 93 DTC 5391, [1993] 1 CTC 280 (Sask. C.A.), briefly aff'd (1994), 120 DLR (4th) 715, [1994] 3 SCR 753 -- summary under Subsection 91(3)

At a time a construction company ("Mid-Plains") abandoned work on a contract for a Crown agency ("TransGas"), TransGas, in addition to holding "holdback" funds as required under the Builders' Lien Act (which were not at issue in the action), held additional contract funds payable to Mid-Plains for the work done under the abandoned contracts. In finding that the federal Crown had a priority under s. 224(1.2) over builders' lien claimants of Mid-Plains with respect to the additional contract funds, Tallis, J.A. found that s. 224(1.2) had as its purpose the expedient collection of withheld tax monies and, therefore, was intra vires the powers of the federal Crown under s. 91(3) of the Constitution Act, 1967.
