Which of the following is Douglass referencing in his speech?

This infamous decision of the Slaveholding wing of the Supreme Court maintains that slaves are within the contemplation of the Constitution of the United States, property; that slaves are property in the same sense that horses, sheep, and swine are property; that the old doctrine that slavery is a creature of local law is false; that the right of the slaveholder to his slave does not depend upon the local law, but is secured wherever the Constitution of the United States extends; that Congress has no right to prohibit slavery anywhere; that slavery may go in safety anywhere under the star-spangled banner; that colored persons of African descent have no rights that white men are bound to respect; that colored men of African descent are not and cannot be citizens of the United States.
