What Brady compliance looks like in 2026

In 1958, a man named John Leo Brady was sentenced to death for his role in a robbery-turned-murder. There was just one problem: prosecutors had withheld a written statement from his accomplice admitting that he, not Brady, had done the killing. That single suppressed document became the basis for one of the most consequential rulings in American criminal law.

When Brady v. Maryland reached the Supreme Court in 1963, the justices held that withholding evidence favorable to a defendant violates due process whenever that evidence is material to guilt or punishment. More than sixty years later, that principle, known simply as the Brady Rule, remains a cornerstone of prosecutorial ethics. But the world it was written for looks almost nothing like the one prosecutors work in today.

A rule built for paper files, applied to petabytes

In 1963, discovery meant a handful of documents. Today, discovery often involves vast amounts of digital information gathered over extended periods of time. What was once a relatively straightforward review process now requires managing a significantly larger volume of material.

Meanwhile, the people responsible for reviewing all of it haven’t gotten more time or staff to do it. Prosecutors’ offices are managing 80 to 150 active cases per attorney, and a striking number are running on fumes: 74% of government legal departments report staffing shortages, and 71% report rising workloads with no corresponding increase in resources.¹ Discovery was never simple. It has become dramatically less so, and the volume shows no sign of slowing down.

The combination of exploding evidence and static resources is exactly the condition under which good people miss things. Not out of carelessness, but because meticulous manual review has limits, and those limits get tested every single day. When something slips through, the costs aren’t abstract: delayed proceedings, resource-draining remediation, and when a Brady violation becomes public, real damage to the public’s trust in the system itself.

The quiet parity problem no one’s talking about

Here’s the part of this story that doesn’t get discussed enough: public defenders and federal courts already have AI tools built for this. Federal public defenders use CoCounsel Legal. So do federal courts and the U.S. Supreme Court. A growing number of state public defender offices have adopted it, too, often because they had smaller budgets and higher caseloads, not despite it.

That creates an uneven courtroom. A prosecutor without a comparable tool is now going up against opposing counsel who can upload a 600-page case file and get a complete analysis — witness lists, timelines, inconsistencies, potential Brady material — in minutes. This isn’t a hypothetical arms race. It’s already happening, and it’s already shaping how cases get prepared and disclosed.

What an AI tool built for this actually looks like

This is where CoCounsel Legal’s design choices matter more than its marketing copy. It’s the only AI legal solution built directly on Westlaw and Practical Law, which means outputs are grounded in authoritative legal content rather than open-web data — and CoCounsel Legal can’t access the open web or fabricate citations. Every case it cites is checked against KeyCite, and every answer arrives with linked, verifiable footnotes.

The efficiency numbers are hard to ignore. Discovery review that used to take eight-plus hours now takes about 90 minutes. Grand jury prep that took 7 to 12 hours drops to roughly 16 minutes.¹ Witness lists that took an hour or two now come together in under two. Drafting time across charging documents, trial briefs, and victim notifications is cut in half.

But speed isn’t the whole story, accountability is. Every step CoCounsel Legal takes is logged and reviewable, producing a documented disclosure record built specifically to satisfy Brady obligations and hold up under appellate scrutiny. Prosecutors can see what was searched, what was planned, and what actually shaped the result, not just the finished output. And nothing entered into the platform is ever used to train the underlying models or accessed by Thomson Reuters; it’s ISO 27001-certified, SOC 2 Type II-compliant, and built to the security standard government legal work demands.

Crucially, none of this replaces prosecutorial judgment. The attorney still drives every decision — CoCounsel Legal just clears away the hours of manual cross-referencing that used to stand between a prosecutor and that judgment call.

A practical test for any AI tool your office is using

If your office already has an AI tool for discovery, it’s worth asking it some pointed questions: Does it produce a complete audit trail? Can every output be traced to an authoritative source? Does it meet government-grade security standards? How does it handle hallucinations? Does it show its reasoning, or just its conclusions?

If the answers make you uneasy, that unease is the point. The Brady Rule hasn’t gotten any less demanding since 1963; the volume of evidence it applies to has just gotten enormous. The offices that adapt their tools to match that reality will be the ones best positioned to meet their constitutional obligations with confidence, not just hope.
