In the case of Stephenson et al. v. Binford et al., 1932, the U.S Supreme Court upheld a Texas statute that regulated trucking within its borders to protect state highways and ensure public safety. The plaintiffs, who were involved in interstate commerce as motor carriers, challenged this law arguing it violated their Fourteenth Amendment rights and was an unreasonable burden on interstate commerce. However, the court ruled against them stating that states have the power to regulate traffic on their highways even if it affects interstate commerce so long as there is no discrimination against or direct regulation of such commerce by these laws. This decision reinforced states' authority over local matters while maintaining federal control over interstate trade.

In the dissenting opinion for Stephenson et al. v. Binford et al., Justice McReynolds argued that the majority's decision was an overreach of federal power, infringing upon states' rights to regulate their own commerce and industries. He contended that the Texas statute in question, which regulated truck weights on state highways, did not interfere with interstate commerce but rather sought to protect public roads from damage caused by heavy vehicles. The justice believed this fell within a state's police powers and should be upheld as constitutional under the Tenth Amendment. Furthermore, he disagreed with the majority’s interpretation of what constituted a burden on interstate commerce; he felt it was too broad and could potentially lead to unwarranted federal interference in local matters.
