Ilya Somin, writing at The Volokh Conspiracy:
Last week, the United Nations Human Rights Council adopted a resolution supporting the suppression of speech that “defames” religion. The resolution is not considered to be binding international law in and of itself, but many experts claim that such resolutions should be considered in determining what counts as “customary international law.” . . .
The UN Human Rights Council resolution also exemplifies a crucial procedural weakness of international human rights law: the extensive role of repressive authoritarian states in determining its content. Most of the nations that voted for the Human Rights Council resolution are oppressive dictatorships, whereas most liberal democracies opposed it.
