The Subpoena Surge: Why Growing Request Volumes Are Creating a New eDiscovery Backlog Crisis

The Subpoena Surge: Why Growing Request Volumes Are Creating a New eDiscovery Backlog Crisis

For years, the eDiscovery industry has focused on one problem: too much data.

Today, there is a second problem that may be just as consequential:

Too many requests.

Subpoenas, litigation demands, regulatory inquiries, third-party records requests, and public-records requests are all placing greater demands on organizations.

And the volume is accelerating.

The result is a growing operational gap between what organizations are being asked to produce and their ability to respond quickly, accurately, and defensibly.

The numbers are sending a clear signal

The increase isn't theoretical.

Recent data from Wolters Kluwer indicates that U.S. subpoena activity increased 67% from 2019 through June 2026. Subpoena-related legal-record orders have reached a seven-year high.

At the same time, government agencies are experiencing record levels of public record information requests.

The Department of Justice received 159,743 FOIA/PPR requests in FY2025, while its backlog grew to more than 29,000 requests.

HHS reported approximately 55,000 FOIA/PPR requests in FY2025—a 66% increase compared with FY2021. Its backlog increased by nearly 65% during the year.

The message for corporate legal departments is straightforward:

The demand for records is growing faster than many organizations' ability to process that demand.

This is not simply a staffing problem

The traditional response to a growing workload is to add people.

That strategy is becoming increasingly difficult to sustain.

Today's requests can span email, text messages, Teams, Slack, cloud applications, databases, mobile devices, collaboration platforms, and increasingly, AI-generated information.

The challenge isn't simply reviewing more documents.

It is finding the right information across an expanding information ecosystem—and proving that the search was complete and defensible.

That changes the economics of eDiscovery.

Every subpoena creates a data-management event

A subpoena may contain only a few lines.

The response can trigger dozens of activities:

Intake. Scope. Custodians. Preservation. Collection. Processing. Search. Deduplication. Review. Privilege. Redaction. Production. Documentation.

Now multiply that workflow by hundreds or thousands of requests.

The problem quickly becomes a queue.

And queues create backlogs.

Backlogs create risk.

The hidden cost of the backlog

A growing subpoena backlog doesn't just consume legal resources.

It can affect deadlines.

It can delay investigations.

It can increase litigation costs.

It can pull IT and business personnel away from their primary responsibilities.

And perhaps most importantly, it can increase the risk of an incomplete or inconsistent response.

When response teams are overwhelmed, even sophisticated technology can become reactive rather than strategic.

Data complexity is making the problem worse

The industry is also moving beyond traditional document discovery.

Structured databases, application data, hyperlinks, collaboration platforms, mobile communications, and generative AI are becoming part of the discovery conversation.

A database cannot always be treated like a collection of documents.

A Teams conversation cannot necessarily be treated like an email.

And an AI interaction may create information that never existed in a traditional records-management system.

The definition of "where the records are" is changing.

Organizations that don't understand their information environment will struggle to respond efficiently when the demand arrives.

AI can be the answer, but it is also the next challenge

Artificial intelligence can help organizations manage growing volumes.

AI-assisted review, enterprise search, classification, analytics, and automated workflows can dramatically reduce manual effort.

But AI also creates new information.

Prompts.

Outputs.

Interaction histories.

Agent activity.

Audit logs.

Generated documents.

The organizations adopting AI therefore face an important paradox:

AI can reduce the cost of responding to records requests while simultaneously expanding the universe of potentially discoverable information.

The answer isn't more people. It's a better system.

Organizations cannot sustainably solve a 67% increase in subpoena volume by simply adding reviewers. Digital WarRoom Private Cloud can be a solution for as little as $1,000/month.

They need to rethink the operating model.

The most resilient organizations will build centralized, repeatable processes for:

• Request intake and prioritization
• Custodian and data-source identification
• Preservation
• Enterprise-wide collection
• AI-assisted search and review
• Deduplication and analytics
• Production
• Audit and reporting

The objective is not simply to process today's request.

It is to create a system capable of handling the next thousand requests.

eDiscovery is moving upstream

This is the bigger transformation.

eDiscovery can no longer be viewed solely as something that begins when litigation starts.

Organizations need to think about information readiness long before the subpoena arrives.

Where is the data?

Who controls it?

How long is it retained?

Can it be searched?

Can it be preserved?

Can it be collected without disrupting the business?

Can the organization demonstrate what it did?

Those questions belong to legal, IT, records management, compliance, and executive leadership—not just the eDiscovery team.

The new competitive advantage: response readiness

The organizations that perform best in this environment won't necessarily be the ones with the biggest legal departments.

They'll be the ones that can respond faster, more consistently, and more defensibly.

The subpoena surge is exposing a fundamental weakness in traditional approaches to records response.

Volume is no longer an exception. Volume is the operating environment.

And when volume becomes the norm, organizations need systems designed for volume.

The Bottom Line

The future of eDiscovery isn't simply about finding information faster.

It's about building an organization that is always ready to find it.

The question executives should be asking isn't:

"How will we handle the next subpoena?"

It should be:

"What happens when we receive 1,000 of them?"
