Disclaimer: I am not an attorney (tho I grew up in a family of attorneys). I had to retype the passages quoted; any typos are mine.
The complaint has two main parts: that Plaintiff was injured by using Njoys; and that Njoy engaged in fraudulent and deceptive advertising and marketing to lure people into buying its products, knowing they were harmful.
Here is what seems to be the main argument for injury:
His "ecigs are dangerous" allegation seems to be based solely on the FDA 2009 study. The 5 references given are: transcript of the FDA press conference announcing the release of the FDA 2009 study; a CNN news article covering the study release (ref'd twice); and the CNN consumer info page on ecigs (referenced twice), which has not been updated for content since 2009. Note that several links were not followable as given in the court document; I had to reroute to arrive at them.
The only other footnote not referencing Njoy's website or packaging refers to an article listing the nicotine content of various vegetables.
The "Consumer Class" McGovern purports to represent is described thus:
The part alleging Njoy's fraud and deception is heavy on legalese, references to various state and federal statutes covering advertising and marketing, and quotes from Njoy's website and packaging. I haven't researched those yet, but gut reaction is that Njoy (having been through this once before in court as we well know) has had their attorneys carefully vet all language used and claims made before releasing them, so I doubt there's much of a case to be made in that regard.
And that's my homework submission for today... Time for recess.
