Discovery as Strategic Leverage
Discovery is expensive, disruptive, and strategically significant. In complex litigation, discovery costs routinely exceed the cost of all other phases of the case combined. The decisions made at the outset of discovery — how aggressively to pursue it, which requests to prioritize, how to structure depositions — shape the case's trajectory more than almost any other early decision.
Most discovery strategy is based on experience and intuition. Data on how courts have ruled on discovery disputes in similar cases, what deposition strategies have been effective in similar fact patterns, and how courts have responded to proportionality challenges can sharpen that intuition significantly.
Scoping Initial Discovery Requests
The discovery proportionality principle — embedded in Rule 26's 2015 amendments — requires courts to limit discovery whose burden or expense outweighs its benefit. In practice, courts apply this analysis with significant variation: some courts are aggressive about limiting overbroad requests, others largely defer to the parties to work discovery out.
Understanding your judge's approach to discovery disputes before you file your initial requests is valuable intelligence. A judge who consistently grants protective orders against overbroad requests calls for more targeted, defensible initial discovery requests. A judge who rarely grants protective orders and expects the parties to fight it out creates different incentives.
Depositions: What the Data Shows About Effectiveness
Deposition strategy is where attorney style and judgment are most important — but patterns still emerge from analyzing successful cases. In document-intensive commercial litigation, depositions that effectively use documents to lock witnesses into positions that are hard to walk back at trial tend to be more effective than exploratory depositions that don't have a clear document foundation.
In employment and civil rights cases, deposition sequencing matters: deposing lower-level witnesses before senior decision-makers typically creates a cleaner foundation for establishing pretext than deposing the decision-maker first.
ESI: Where Discovery Battles Are Actually Won and Lost
Electronically stored information management is where modern discovery strategy is most consequential and most technically demanding. The key decisions:
- Custodian selection: Which employees' communications and documents are most likely to contain the relevant evidence? Analytical tools that analyze email patterns and document metadata can identify key custodians more reliably than organizational chart analysis alone
- Search term negotiations: The hit rates and responsiveness rates from search term testing should drive term selection — terms that generate 5% responsiveness rates are worth fighting for; terms that generate 0.2% responsiveness rates may not be
- Technology-assisted review: Courts have become increasingly comfortable with TAR/predictive coding; the litigation record on TAR protocol disputes is well-developed enough that known-effective protocols should be adopted rather than invented from scratch
Discovery Sanctions: What Gets Courts' Attention
Analysis of discovery sanction decisions reveals what truly gets courts to act: ESI preservation failures after clear litigation holds are triggered, documented discovery responses that are materially false (not just incomplete), and persistent discovery obstruction after court intervention. Courts are generally reluctant to impose dispositive sanctions — adverse inference instructions and cost-shifting are the more common remedies — but they will act decisively when spoliation is clear and significant.
Understanding the standard for sanctions in your jurisdiction before a discovery dispute arises allows you to both comply with your own obligations precisely and to build a clear record when opposing counsel is failing to comply with theirs.
Integrating Analytics into Discovery Planning
The most effective integration of data analytics into discovery strategy happens at the planning stage — before the initial conference with opposing counsel. Understanding how courts have resolved discovery disputes in similar cases, how your judge approaches proportionality, and what deposition strategies have been effective in similar fact patterns creates a discovery plan that is strategically grounded rather than reflexively aggressive or defensive.
