After a four-day-long trial, a jury took less than an hour to decide that Tesla CEO Elon Musk did not defame British caver Vernon Unsworth when he sent a tweet calling Unsworth “pedo guy.”

The verdict was announced Friday afternoon.

Unsworth, who participated in the rescue of 12 boys and their soccer coach trapped for weeks in a Thailand cave last year, had sought $190 million in damages for the shame and humiliation caused by the man his lawyer called a “billionaire bully.”

It took less than an hour for an eight-person jury in Los Angeles federal court to reject Unsworth’s claim after a four-day trial.

Musk said the verdict restored his faith in humanity as he quickly left the court with his security detail.

Musk — who deleted the tweet and later apologized for it — had asserted the expression was nothing more than a flippant insult that meant “creepy old man,” not pedophile.

Unsworth had provoked the attack by belittling Musk’s contribution to the rescue — a miniature sub his engineers built that was never used — as ineffective and nothing more than a “PR stunt.” He further earned the ire of the tech whiz by suggesting Musk stick the sub “where it hurts.”

On Friday, it was Unsworth who felt the pain.

“I accept the jury verdict, take it on the chin, and move on,” Unsworth said outside court.
