The point I think OP was making is that you can say anything with a reasonable evidentiary basis in a complaint. (And some lawyers don't bother with the evidentiary basis part—see the post-election lawsuits that are being sanctioned for just that.) It's not about whether the language is in the article or the legal document; the legal document itself is merely a lawyer saying something that is in their client's interest.
