I find the title is misleading. Title implies that the vote was wether to condemn or not.

While I did not read the full PDF (underlaying document for this vote), the title of the document is Declaration of the Trafficking of Enslaved Africans and Racialized Chattel Enslavement of Africans as the Gravest Crime against Humanity and part of it is about paying reparations.
