Tesla Inc. CEO Elon Musk earned the nickname "Teflon Elon” by successfully fighting off multiple legal challenges. But a recent court ruling suggests his run of personal victories may be endangered.

Last week, it was revealed that a San Francisco judge had determined that one of Musk’s 2018 tweets about taking his company private was a lie.

It’s one of at least a dozen high-profile cases that Tesla or Musk are involved in years after he posted the infamous "funding secured” tweet, sending shares soaring and inviting the wrath of the U.S. Securities and Exchange Commission.
