Brandeis, the associate justice on the Supreme Court of the United States filed a brief citing scientific and sociological studies to demonstrate that because women had less strength and endurance than men, long hours of labor were dangerous for them.

Oregon was  made by the Supreme Court, which justifies on sex discrimination, women’s working condition and limitation on their maximum working hour to protect  women’s safety and health.
