In the case of People of the State of Illinois ex rel. Gersch v. City of Chicago et al., 1912, the Supreme Court was asked to determine whether a city ordinance that required all vehicles for hire to be licensed and regulated by the city violated constitutional rights. The plaintiff, Gersch, argued that this regulation infringed upon his right to conduct business freely without undue interference from government authorities. However, after careful consideration, the court ruled in favor of City of Chicago stating that such regulations were within its police powers as they were enacted with public safety and welfare in mind - ensuring drivers are competent and vehicles are safe for use is a legitimate concern for local governments. Therefore it did not violate any constitutional provisions or infringe on individual liberties unduly.

In the dissenting opinion for PEOPLE OF THE STATE OF ILLINOIS EX REL. GERSCH, v. CITY OF CHICAGO et al., 1912, it was argued that the majority's decision to uphold a city ordinance prohibiting peddling in residential areas violated individual rights and liberties protected by both state and federal constitutions. The dissenting justices contended that such an ordinance unfairly restricted trade and commerce, thereby infringing upon personal freedoms without just cause or sufficient public interest. They further asserted that this ruling set a dangerous precedent of allowing local governments to arbitrarily limit individuals' economic activities based on their location within the city limits. This viewpoint emphasized the importance of maintaining constitutional protections against undue governmental interference in private affairs.
