David Lienhelm & Sarah Hanson Young

Did Lienhelm based on what he said on Sky Outsiders in regards to Sarah Hanson Young or at any time. Expose himself to legal action from Sarah Hanson Young? I've tried reading a little bit online on this issue and watching some videos. However I am finding it rather difficult to conclude if what he said was legal or not. I airing on the side of it being illegal but am I right? More information can be found via Google since this subreddit does not permit for certain links.
