A jury decided that Elon Musk had not defamed British caver Vernon Unsworth in a Los Angeles federal court on Friday.
"My faith in humanity is restored," said Musk in court after the verdict was delivered.
The jury deliberated for only an hour before delivering its verdict in the case, which went to trial earlier this week.
In his testimony during the defamation trial this week, Musk apologized to Unsworth and said he did not believe the cave explorer was a pedophile.
Musk and his defense team, led by attorney Alex Spiro, argued that "pedo guy" was simply heated rhetoric and not meant as a statement of fact.
He said Musk could "stick his submarine where it hurts," and viewed the escape pod as "just a PR stunt.".
Vernon Unsworth vs. Elon Musk was one of the first major defamation lawsuits --brought by a private individual over a tweet-- to ever go to trial. »
