How did the lawyer for the state of Oregon convince the supreme court to uphold a law that limited women to a 10 hour work day?

The lawyer for the state of Oregon argued that the law limiting women to a 10-hour workday was justified on the grounds of protecting women's health and welfare, as well as their role in society. He emphasized the physical demands of labor and the need for safeguards to ensure women's well-being, appealing to a societal interest in preserving maternal health and family stability. The argument framed the law as a means to promote the broader social good, which ultimately convinced the Supreme Court to uphold the regulation.
