The 2024 decision in In re StubHub Refund Litigation marked a turning point in how courts view discovery obligations. The issue was whether producing massive volumes of electronically stored information (ESI) was proportional to the needs of the case. The court’s reasoning was clear: discovery must be defensible, measured, and cost-conscious, not a limitless burden.

StubHub is more than a precedent. It reflects the ediscovery challenges that now define e-discovery in 2025—managing explosive data growth, integrating AI responsibly, meeting rising expectations of technical competence, ensuring preservation across ephemeral platforms, and protecting sensitive information in high-stakes disputes.

Each area presents risks, but also opportunities for firms that adopt smarter practices. So, let’s take a look at the ediscovery challenges, solution and impact.

E-Discovery Challenges and Strategies Every Legal Team Must Know

1. Data Volume and Proportionality

In StubHub, the dispute centered on whether the scope of production was disproportionate to the burden. Courts signaled that sheer volume is no defense—lawyers must show how discovery aligns with the principles of proportionality.

  • Challenge: Data sets in 2025 extend beyond emails to terabytes of Slack messages, shared documents, and video files. Traditional review approaches collapse under this weight.
  • Solution: Early case assessment and analytics-based culling help narrow data before review. Using sampling and predictive filtering demonstrates a disciplined approach to proportionality.
  • Impact: Firms that master proportionality cut discovery costs, reduce client frustration, and build credibility with courts. Those who fail risk sanctions and wasted resources.

2. AI and Privilege Review

StubHub did not hinge on AI-assisted review, but its scale illustrates why AI is increasingly relied upon. While AI accelerates classification, it also raises privacy risks that cannot be ignored.

  • Challenge: Misclassification by AI can expose privileged or confidential materials, jeopardizing strategy and inviting disputes.
  • Solution: Pair AI with human-in-loop verification, maintain audit trails, and negotiate robust clawback provisions tailored to AI risks.
  • Impact: This balance preserves the efficiency benefits of AI while protecting privilege and demonstrating to courts that review methods are defensible.

3. Technology Competence

A broader lesson from StubHub is that courts expect legal teams to competently manage the tools they employ. Technical missteps are no longer viewed as excusable mistakes but as professional lapses.

  • Challenge: Inadequate command of discovery platforms or AI tools undermines both client confidence and judicial trust.
  • Solution: Regular training, reliance on litigation support professionals, and clear documentation of workflows ensure that counsel can meet rising expectations.
  • Impact: Demonstrates compliance with the duty of technological competence, mitigates malpractice risks, and reassures clients that their cases are handled with rigor.

4. Preservation Obligations

StubHub also underscores the importance of proactive preservation. Courts today are less tolerant of discovery gaps, particularly as ephemeral data becomes central to disputes.

  • Challenge: Messaging apps and collaboration platforms auto-delete or overwrite content, creating spoliation risks.
  • Solution: Implement litigation holds early, engage IT to capture high-risk data sources, and document all preservation steps.
  • Impact: Avoids sanctions, protects evidentiary integrity, and signals to courts that preservation has been handled responsibly.

5. Specialized Litigation Risks

Though StubHub was not an intellectual property matter, its lessons extend easily. In IP disputes, discovery often involves proprietary research and trade secrets. Mishandling such data can cause competitive harm that extends far beyond the courtroom.

  • Challenge: Balancing discovery obligations with safeguarding sensitive IP and confidential business data.
  • Solution: Use protective orders, targeted production, and confidentiality protocols that protect IP while meeting obligations.
  • Impact: Preserves competitive advantage, ensures compliance, and demonstrates to clients that litigation risks are being managed strategically.

Conclusion

In re StubHub Refund Litigation is not just a 2024 precedent; it is a roadmap for 2025. The case illustrates that discovery is no longer about producing “more,” but about producing smarter—with proportionality, defensibility, and competence as guiding principles.

For firms and in-house counsel, the path forward is clear: adopt structured approaches to proportionality, govern AI responsibly, invest in competence, and preserve proactively. These steps not only avoid judicial sanctions but also reassure clients that discovery is being managed strategically and efficiently.

For many, the most practical way to achieve this will be through litigation support services that combine technology oversight, cost management, and compliance expertise. StubHub’s lesson is simple: in 2025, discovery will define outcomes—and those prepared to meet its challenges will define success.
