“Since the narrower or wider community of the peoples of the earth has developed so far that a violation of rights in one place is felt throughout the world, the idea of a cosmopolitan right is not fantastical, high-flown or exaggerated notion. It is a complement to the unwritten code of the civil and international law, necessary for the public rights of mankind in general and thus for the realization of perpetual peace.”

1960s, First court statement (1962)
Context: In its proper meaning equality before the law means the right to participate in the making of the laws by which one is governed, a constitution which guarantees democratic rights to all sections of the population, the right to approach the court for protection or relief in the case of the violation of rights guaranteed in the constitution, and the right to take part in the administration of justice as judges, magistrates, attorneys-general, law advisers and similar positions.
In the absence of these safeguards the phrase 'equality before the law', in so far as it is intended to apply to us, is meaningless and misleading. All the rights and privileges to which I have referred are monopolized by whites, and we enjoy none of them. The white man makes all the laws, he drags us before his courts and accuses us, and he sits in judgement over us.

The Ballot or the Bullet (1964), Speech in Cleveland, Ohio (April 3, 1964)
Context: When you expand the civil-rights struggle to the level of human rights, you can then take the case of the black man in this country before the nations in the UN. You can take it before the General Assembly. You can take Uncle Sam before a world court. But the only level you can do it on is the level of human rights. Civil rights keeps you under his restrictions, under his jurisdiction. Civil rights keeps you in his pocket. Civil rights means you’re asking Uncle Sam to treat you right. Human rights are something you were born with. Human rights are your God-given rights. Human rights are the rights that are recognized by all nations of this earth. And any time any one violates your human rights, you can take them to the world court.
