Can Minnesota's statute survive a constitutional challenge against Clover?

Answer 1

Yes because ,The statute does not violate the Commerce Clause as constituting an unreasonable burden on interstate commerce

The statute does not discriminate between interstate and intrastate commerce but regulates evenhandedly by prohibiting all milk retailers from selling their products in plastic containers, without regard to whether the milk, the containers, or the sellers are from outside the State

The incidental burden imposed on interstate commerce by the statute is not excessive in relation to the putative local benefits. Milk products may continue to move freely across the Minnesota border, and since most dairies package their products in more than one type of container, the inconvenience of having to conform to different packaging requirements in Minnesota and the surrounding States should be slight. Even granting that the out-of-state plastics industry is burdened relatively more heavily than the Minnesota pulpwood industry, this burden is not "clearly excessive" in light of the substantial state interest in promoting conservation of energy and other Natural Resources and easing solid waste disposal problems. These local benefits amply support Minnesota's decision under the Commerce Clause.
