Pennsylvania."[596] THE ROBBINS CASE TODAY In the cases reviewed in the preceding paragraph protestants against local taxation appealed, but unavailingly, to the Robbins case. So it would seem that the generative powers of that prolific precedent had begun to wane somewhat even before the Depression, an event which rendered judicial reaction against it still more pronounced. Indeed, by the Court's decision in McGoldrick _v._ Berwind-White Co.,[597] in 1940, the authority of the entire line of cases descending from Robbins _v._ Shelby County Taxing District was seriously impaired, for the time being, while a second holding the same year seemed to reduce the significance of the Robbins case itself to that of a reassertion of the elementary rule against discrimination. "The commerce clause," Justice Reed remarked sententiously, "forbids discrimination, whether forthright or ingenious."[598] DEPRESSION CASES: USE TAXES With a majority of the States on the verge of bankruptcy, extensive recourse was had to sales taxes and, as an offset to these in favor of the local economy, "use" taxes on competing products coming from sister States. The basic decision sustaining the use tax, in this novel employment of it, was Henneford _v._ Silas Mason Co.,[599] in which was involved a State of Washington two per cent tax on the privilege of using products coming from sister States. Excepted from the tax, on the other hand, was any property the sole use of which had already been subjected to an equal or greater tax, whether under the laws of Washington or any other State. Stressing this provision in its opinion, the Court said: "Equality is the theme that runs through all the sections of the statute. * * * When the account is made up, the stranger from afar is subject to no greater burdens as a consequence of ownership than the dweller within the gates."[600] There being no actual discrimination in favor of Washington products, the tax was valid.
