Elon Musk is seeking to dismiss a defamation claim by saying that “over-the-top” paedophilia claims he tweeted should not be taken seriously.
He is being sued by Vern Unsworth, who aided the rescue of 12 boys from Thailand’s Tham Luang caves.
The two clashed over how to free the boys in an exchange that led to Tesla’s chief calling Mr Unsworth “pedo guy”.
Mr Musk’s lawyers said the “insult” had been made in response to Mr Unsworth’s own disparaging remarks.
Mr Unsworth is from St Albans, Hertfordshire, but now lives near Chiang Rai in Thailand.
