A WP editor just happens to find a copy of the original suit and writes about it in Joe Foo's article. Nobody anywhere else is writing about Joe Foo getting sued.
Since nobody else has written about Joe Foo getting sued, the suit itself is non notable and therefore the information in Joe Foo's article about the suit is removed by Jimbo.
No. Jimbo never mentioned notability. He removed it on OR and NPOV grounds. (Mainly NPOV, I think, the comments about OR were just to explain where the writer had gone wrong.)
