Background

Investors suing Jack Dorsey and other defendants over allegations concerning Block sought documents that the defendants had supplied to the U.S. Department of Justice during a government investigation. The investigation overlapped substantially with allegations drawn from a March 2023 Hindenburg report that also underlie the civil complaint.

A magistrate judge ordered the defendants to reproduce all nonprivileged documents they had provided to DOJ, except transaction-level customer data. Materials received from DOJ were outside the order. The defendants asked the district judge to set that discovery ruling aside, arguing that production of the collection was too broad and burdensome.

The Court’s Holding

The district court denied relief and left the production order intact. A district judge may overturn a magistrate judge’s nondispositive pretrial ruling only if it is clearly erroneous or contrary to law, a deliberately deferential standard.

The court found that the magistrate judge properly applied Federal Rule of Civil Procedure 26. The overlap between the DOJ investigation and the civil action made the collection likely to contain relevant information, and the magistrate judge had expressly weighed the burden of reproducing the documents against the needs of the case. Excluding customer-level transaction data also narrowed the production. The defendants therefore did not show the definite mistake required to disturb the ruling.

Key Takeaways

  • A prior production to a government investigator can become an efficient and discoverable collection in related private litigation.
  • Privilege remains protected, but a party cannot defeat discovery merely because relevant documents were assembled for a government investigation.
  • Challenges to a magistrate judge’s discovery order face the demanding clearly-erroneous-or-contrary-to-law standard.
  • A proportionality analysis is stronger when the order identifies exclusions and directly compares burden with likely relevance.

Why It Matters

California companies responding to government investigations should assume that nonprivileged productions may later be sought wholesale in overlapping shareholder or consumer litigation. Careful privilege review, defensible collection records, and clear separation of sensitive customer data can materially affect the scope of later discovery.

For litigators, the order also shows the value of framing discovery around an already curated investigative record. Once a magistrate judge makes explicit relevance and proportionality findings, obtaining district-court reversal will usually require more than disagreement over breadth or expense.
