“ It characterizes the law as 'retaliatory'; argues, among other things, that the Amendment may not be interpreted as permitting retaliation; and insists that such interpretation would defeat its purpose, as thereby Michigan would be allowed to punish Indiana for doing what, under the rule applied in State Board of Equalization v. Young's Market Co., 299 U.S. 59, 63, 57 S.Ct. 77, 78, 81 L.Ed. 38, is permitted. Whether the Michigan law should not more properly be described as a protective measure, we have no occasion to consider. For whatever its character, the law is valid. ”
