The Oversight Board is a body that makes consequential precedent-setting content moderation decisions (see below) on the social media platforms Facebook and Instagram. Facebook CEO Mark Zuckerberg approved the creation of the board in November 2018, shortly after a meeting with Harvard Law School professor Noah Feldman, who had proposed the creation of a quasi-judiciary on Facebook. Zuckerberg originally described it as a kind of "Supreme Court", given its role in settlement, negotiation, and mediation, including the power to override the company's decisions.
