"Establishing structure and governance for an independent oversight board," 17 Sept 2019

... We’re announcing more details on the structure of the Oversight Board and its relationship to Facebook in the form of a charter. This central governing document defines the board’s mandate and describes its relationship to Facebook... We often received a key piece of feedback: make sure the board is independent from Facebook. One way we’re addressing this is by establishing an independent trust. The Oversight Board, the trust and Facebook will have separate roles and responsibilities... Both Facebook and its users will be able to refer cases to the board for review. For now, the board will begin its operations by hearing Facebook-initiated cases. The system for users to initiate appeals to the board will be made available over the first half of 2020.
