In the case of Interstate Busses Corporation v. Holyoke Street Railway Company in 1926, the Supreme Court ruled on a dispute between two transportation companies over interstate commerce rights. The Interstate Busses Corporation had been granted permission by Massachusetts to operate its buses along certain routes within the state, but was denied access to some streets controlled by Holyoke Street Railway Company. The bus company sued, arguing that this denial violated their right to engage in interstate commerce as protected under federal law. However, the Supreme Court sided with Holyoke Street Railway Company and upheld their decision to deny access based on local regulations and public safety concerns. This ruling affirmed that states have significant authority over local transportation matters even when they intersect with interstate travel.

In the dissenting opinion for Interstate Busses Corporation v. Holyoke Street Railway Company, it was argued that the majority's decision to uphold a Massachusetts law prohibiting interstate buses from picking up passengers within state lines for transport to another point in the same state was incorrect. The dissenting justices believed this ruling violated the Commerce Clause of the U.S Constitution by allowing states to regulate and restrict interstate commerce. They contended that while states have rights over their internal affairs, they should not be allowed to interfere with or control commercial activities crossing their boundaries as these are inherently part of an integrated national system. Furthermore, they disagreed with majority’s interpretation of previous court rulings on similar issues and insisted those precedents supported a more expansive view of federal power over interstate commerce.
