Does anyone have a source of what the citations were?

I didn't see them mentioned in the article.

The article links to the opinion[1], which notes more than once that "the quoted language does not appear anywhere in the opinion," and "Goldstine appears to be a fabricated case." I don't know whether it's easy to get a copy of the complaint in question.
