It was the best of privilege times, it was the worst of privilege times. A federal court sustained Tesla‚Äôs privilege defense to avoid producing its internal investigation even though there was some evidence that its investigations were ‚Äústandard practice.‚ÄĚ Tesla, Inc. v. Cao, 2020 WL 8515010 (N.D. Cal. Dec. 10, 2020) (available here). But, later, the court rejected Tesla‚Äôs attempt to obtain a competitor‚Äôs privileged investigation even though the competitor‚Äôs executive publicly disclosed the results of that investigation. Tesla, Inc. v. Cao, 2021 WL 540351 (N.D. Cal. Jan. 19, 2021) (available here).

It was the Age of Wisdom, it was the Age of Foolishness

Tesla sued one of its former engineers, Guanghi Cao, alleging that he uploaded Tesla‚Äôs Autopilot source code and took that proprietary information to a competitor, Xiaopeng Motors Technology Company. Calling this source code the ‚Äúcrown jewel of Tesla‚Äôs intellectual property portfolio,‚ÄĚ Tesla sought significant monetary damages.¬† For his part, Cao admitted uploading the source code, but denied that he used it at Xpeng.

And although the case recently settled, two privilege opinions related to internal investigations remain relevant.

It was the Epoch of Belief

During discovery, Cao sought production of the notes from and summaries of interviews conducted by Tesla‚Äôs internal investigators. Tesla lawyers did not prepare these notes and summaries but attended some‚ÄĒbut not all‚ÄĒof those interviews.¬† Cao further claimed that, as admitted by a Tesla employee, it was ‚Äústandard practice‚ÄĚ of conducting interviews and writing summaries during an investigation.¬† For these reasons, Cao argued, Tesla conducted the internal investigation for routine business purpose and not for the purpose of obtaining legal advice.

The court noted, however, that the corporate attorney‚Äďclient privilege protects communications from the client‚Äôs employees to the client‚Äôs lawyer‚ÄĒor the lawyer‚Äôs subordinates. And Tesla proved that the primary purpose of the interviews was to secure legal advice. Tesla showed that its interviewers, while not lawyers, conducted the interviews for counsel to provide legal advice. Tesla‚Äôs lawyers reviewed the interview transcripts and assessed the legal landscape by reviewing the notes and summaries saved to an investigation file.

The court brushed aside the ‚Äústandard practice‚ÄĚ testimony, saying that, even if true, that does not foreclose a finding that Tesla conducted this particular investigation for the purpose of obtaining legal advice. And because Tesla proved the legal-advice element, the court upheld the privilege.

It was the Epoch of Incredulity

Xpeng, too, conducted an internal investigation into whether the engineer Cao or other Xpeng employees used Tesla’s Autopilot source code. Tesla wanted access to the investigation results but Xpeng, following Tesla’s earlier lead, claimed that the privilege protected it.  Understanding the court’s position on privileged internal investigations, Tesla challenged the privilege objection on waiver grounds, not legal-advice grounds.

And with good reason.¬† Xpeng‚Äôs CEO, Xinzhou Wu, filed a declaration, available here, stating that, to his knowledge, Cao never provided Tesla‚Äôs source code to Xpeng employees. Tesla‚Äôs lawyers deposed him and asked the basis for this statement and Wu said that the basis was Xpeng‚Äôs investigative report.¬† But Xpeng‚Äôs lawyers objected to further questioning about the report’s content, claiming privilege.

The court rejected Tesla‚Äôs waiver argument because Wu‚Äôs testimony about the basis of his denial was ‚Äúconclusory and undetailed.‚ÄĚ The court held that waiver does not occur where a disclosure about an internal investigation is ‚Äúlittle more than ‚Äėundetailed conclusions about its investigation,‚Äô and were not used in support of a legal claim.‚Ä̬† Xpeng‚ÄĒhere a third party‚ÄĒwas not discussing its investigation as part of claim or defense but in response to discovery-related questions.¬† And that is insufficient, the court ruled, to find privilege waiver.

So, Tesla enjoyed the spring of privilege hope but also endured the winter of privilege despair. Let us all remember why in our own privilege tales.
