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.
