In the case of Texas & New Orleans Railroad Company v. Gross, 1910, the U.S Supreme Court ruled in favor of the railroad company. The dispute arose when Mr. Gross was injured while working for the railroad company and sued for damages under a Texas statute that held employers liable for injuries caused by negligence of fellow employees. However, this law conflicically with federal legislation known as Employers' Liability Act which limited employer liability to cases where injury resulted from negligence of officers or those who were entrusted with superintendence or management duties. The court found that since interstate commerce was involved (as Mr.Gross's work related to maintaining an interstate railway), federal law took precedence over state law according to Supremacy Clause in Constitution.The court concluded that Congress intended its act to be exclusive remedy available against railroads engaged in interstate commerce and therefore pre-empted any conflicting state laws on same subject matter.This decision reinforced principle that federal laws regulating interstate commerce are supreme over conflicting state statutes.

In the dissenting opinion for Texas & New Orleans Railroad Company v. Gross, it was argued that the court majority erred in its interpretation of the law and application to this case. The dissent contended that there was no legal basis for holding a railroad company liable for injuries sustained by an employee while performing his duties if he had knowledge of potential hazards associated with those duties. It was further stated that such liability would be unjust as it would place undue burden on employers who could not possibly eliminate all risks inherent in certain types of work, especially within industries like railroads where danger is often unavoidable due to nature of tasks involved. Additionally, they disagreed with majority's view about negligence being a question for jury rather than matter of law; arguing instead that courts should have final say over what constitutes negligence based on established legal principles rather than leaving such important determinations up to laypersons without any formal legal training or expertise.
