Anne Twomey recently published an interesting video about the eSafety v. Baumgarten court case: https://www.youtube.com/watch?v=t9H3uMvREWg

Essentially eSafety has been issuing takedown requests outside of its statutory functions, using the same communication channels for the statutory takedowns.

When called on it, they claimed these decisions were not reviewable because they were outside of the functions the law said were reviewable.
