Dred Scott v. Sandford is a landmark decision enacted by the US Supreme Court in 1857. Dred Scott a was black men and also a slacve who had sued for his freedom after his owners brought him to a free state, where slavery was unconstitutional.
The US Supreme Court declared that those who had been imported and sold as slaves, independently on whether they were slaves or free men afterwards, could never have access to US citizenship and therefore could not enjoy the rights of a US citizen such as standing to sue in a federal court.
