The Ethical Rules for Researching Jurors: What Every Attorney Must Know Before Jury Selection

For most of legal history, researching jurors meant sending an investigator to knock on doors or hiring a jury consultant to dig through public records. The ethical considerations were manageable because the tools were limited. That calculus changed completely with the internet — and then changed again with social media.

Today, an attorney can access a prospective juror's social media profile, professional history, public records, and years of posted opinions in minutes. The potential intelligence value is enormous. So is the potential for ethical missteps. Bar associations across the country — and the American Bar Association itself — have issued formal guidance to help attorneys navigate this landscape. But the rules are nuanced, jurisdiction-specific, and widely misunderstood.

This article breaks down the legal and ethical framework governing juror research: what's permissible, what's prohibited, and what your obligations are when research uncovers something that changes everything.

Why Ethical Considerations in Juror Research Have Become Unavoidable

The jury selection process has always involved some degree of background research on potential jurors. What's changed is the scale, speed, and depth of what's now possible — and the legal implications of how attorneys use those capabilities.

A generation ago, conducting online research on a juror panel simply wasn't an option. Today, it's the baseline expectation. Attorneys who fail to research jurors prior to voir dire may be failing their clients. Attorneys who research jurors without understanding the applicable ethical rules may be failing their professional obligations — and putting their verdicts at risk.

State and local bar associations were among the first to recognize this tension and issue guidance. The ABA followed with formal opinions that established a national framework. Courts have weighed in with standing orders and jury instructions. And disciplinary bodies have sanctioned attorneys who crossed lines — sometimes without knowing those lines existed.

The consequences of non-compliance are serious. A sanction for improper communication with jurors can range from a formal reprimand to fee forfeiture to referral for disciplinary proceedings. In more serious cases, evidence of attorney misconduct during the jury selection process has been used to support motions for a new trial. A verdict won on a tainted jury is not a verdict worth having.

That makes understanding the ethical framework around researching jurors not just a matter of professional responsibility — it's a matter of protecting your client and your case.

How to Investigate Jurors Within the ABA Framework

The definitive national guidance on juror research comes from ABA Formal Opinion 466, issued by the ABA's Standing Committee on Ethics and Professional Responsibility in 2014. It remains the foundational ethics opinion on this issue and the primary reference point for attorneys and ethics committees nationwide.

The core holding of Formal Opinion 466 is straightforward: an attorney may review a juror's publicly available social media profile and conduct internet research on prospective jurors, provided that research is passive and does not involve any communication with the juror.

Under ABA Model Rule 3.5, which governs conduct with jurors and venire members, counsel is prohibited from communicating with a juror or prospective juror except as permitted by law or court order. This is an absolute prohibition — it does not have a good-faith exception, and it applies regardless of the attorney's intent.

Reviewing a juror's public social media profile is, in the ABA's framing, no different from driving down the juror's street to observe their neighborhood. It's passive observation of information that is publicly accessible. The juror has made that information available to the world, and an attorney reviewing it is doing nothing more than what any member of the public could do.

The ABA model framework is clear on several specific prohibitions:

• Sending a friend request or connection request to a prospective juror constitutes an impermissible communication, regardless of whether the juror accepts it
• Asking a third party to conduct research that the attorney themselves could not ethically conduct is equally prohibited
• Any communication prohibited by Model Rule 3.5 remains prohibited whether it occurs in person, by phone, by email, or through a social media platform

What State Bar Associations Say About Online Research of Prospective Jurors

While the ABA framework provides the national baseline, state bar associations have issued their own ethical opinions that attorneys must also consult. State and local bar associations have been active in this space, and in some jurisdictions the guidance is more specific — or more restrictive — than the ABA Model.

The New York City Bar Association's Committee on Professional Ethics issued a formal opinion addressing electronic social media research of prospective jurors that largely tracks the ABA approach but adds important nuance around what constitutes an impermissible communication in the context of automated platform features. The NYC Bar's guidance has been influential in shaping how attorneys in New York approach online investigations.

The San Diego County Bar Association similarly issued ethics guidance addressing online research of prospective jurors, focusing on what counsel may access through social media searches without triggering contact rules. Like the ABA, the San Diego County Bar draws the line at publicly available information and prohibits any conduct that would put the juror on notice of being researched.

The state bar associations of California, Colorado, and New York have all addressed these issues through formal opinions or ethics committee guidance. Each jurisdiction has its own rules regarding what is permissible, and attorneys practicing in multiple jurisdictions must check the applicable guidance for each court where they appear.

The consistent thread across state bar positions is this: passive review of a juror's public social media profile is generally permissible; anything that triggers awareness in the juror that they are being researched, or that involves accessing non-public information, is not.

The Automated Notification Problem: Where Technical Features Create Ethical Landmines

One of the most important and often overlooked issues in juror research ethics is the automated notification problem — and it's the area where well-intentioned attorneys have most frequently found themselves in trouble.

The issue arises when a social media service sends an automated notice to a user when someone has viewed their profile. LinkedIn is the most common example. When an attorney visits a juror's LinkedIn profile while logged into their own account, LinkedIn's default settings will generate a notification alerting the juror that someone viewed their profile. If that attorney is counsel in a pending matter, this automated notice — generated entirely by the platform, without any deliberate act by the attorney — may itself constitute an impermissible communication.

ABA Formal Opinion 466 addressed this directly. The ABA concluded that when a social media service sends an automated notice to a juror informing them that an attorney has viewed their profile, that notification is a communication to a juror asking the juror — implicitly, at least — to take notice of the attorney's interest. Even though the communication is technically generated by the platform rather than the attorney, it is attributable to the attorney's act of visiting the profile.

This is not a theoretical risk. A juror may become aware through a platform notification that an attorney involved in their case has been reviewing their profile. That knowledge can affect juror behavior, raise questions about intimidation, or form the basis for a misconduct complaint. Several state bar opinions have specifically flagged this scenario as one where counsel must exercise caution.

The practical implication: attorneys must be careful about which platforms they use for juror research and how they access them. Platforms and tools that allow passive, anonymous access to publicly available information eliminate this risk entirely. The same logic extends to any feature that would result in a communication to a juror based on a technical action taken by the attorney or their research tools.

Juror Misconduct: Your Ethical Obligation When Research Uncovers a Problem

The ethical obligations around researching jurors don't end when you find useful information. They also govern what you must do when that research reveals potential juror misconduct — and this is an area where many attorneys are unclear on their duties.

Evidence of juror misconduct can surface in several ways during online investigations. A juror may have posted about the case on social media. A juror may have concealed relevant background information during voir dire. A juror's profile may reveal connections to a party, witness, or counsel involved in the case. In each scenario, identifying jurors who have engaged in misconduct creates an immediate ethical obligation.

Attorneys must disclose evidence of juror misconduct to the court. This is not discretionary. Model Rule 3.5 and corresponding rules in virtually every jurisdiction require counsel to report known juror misconduct to the trial judge. Sitting on that information — or attempting to use it strategically after a verdict — is itself a professional ethics violation.

A juror's social media activity during trial is a specific concern that many courts now address through standing orders and jury instructions that explicitly prohibit jurors from using social media platforms to discuss or research matters involved in the case. When counsel discovers that a juror has violated these instructions, prompt disclosure to the trial judge is required.

The ethical obligation to report is uncomfortable — particularly when the misconduct might benefit your client — but it is non-negotiable. Jurors' social media accounts are a legitimate research tool; they are not a source of tactical advantage when they reveal misconduct that must be reported.

Building a Compliant Juror Research Process for Your Trial Team

Understanding the ethical framework is necessary. Having a research process that implements it consistently is what actually protects you. Here's what a compliant approach to researching jurors looks like in practice.

Start with the ABA framework, then check your jurisdiction. Formal Opinion 466 is the baseline, but your state bar's ethics committee may have issued more specific guidance. Before trial, confirm what is permissible in the jurisdiction where you're appearing and ensure your research process reflects those rules.

Stick strictly to publicly available information. The research of prospective jurors must be limited to what is accessible without logging in, without sending a request, and without triggering any notification. If accessing information requires any action that could put the juror on notice, it's off-limits.

Never send a friend request or connection request. This is the single most common way attorneys inadvertently create an impermissible communication with a juror. A friend request — whether accepted or not — is a communication to a prospective juror. It is prohibited under every applicable ethics opinion and under Model Rule 3.5 directly.

Document your process. Maintain a clear record of what social media searches were conducted, what platforms were used, and what information about jurors was reviewed. This documentation demonstrates compliance and protects you if the research process is ever challenged.

Act on what you find. If review of a juror's profile reveals potential juror misconduct — dishonesty during voir dire, improper case research, undisclosed connections — report it to the court immediately. Your ethical obligation to disclose is not contingent on the tactical consequences.

Use purpose-built tools to eliminate manual risk. The most reliable way to ensure your juror research stays within ethical limits is to use platforms designed specifically for that purpose. PeerProbe's Social Media Review feature was built to handle exactly this — surfacing publicly available social media information on prospective jurors without triggering notifications, sending any form of contact, or accessing non-public information. Every search leaves no footprint. Every finding is documented with a full audit trail.

Conclusion

The ethical rules governing juror research are clear in their principles: passive review of publicly available information is permissible; active contact, however indirect, is not. The ABA, state bar associations, and courts across the country have said as much, repeatedly and consistently. But the technical realities of modern social media platforms — automated notifications, profile view alerts, connection features — mean that well-intentioned research can cross ethical lines without the attorney ever intending it.

The solution isn't to avoid juror research — in the digital age, that would be a disservice to your clients. The solution is to build a research process that is compliant by design: one that stays within the boundaries established by Formal Opinion 466 and applicable state guidance, documents what was found and how, and uses tools that eliminate the manual risk of inadvertent ethical violations.

PeerProbe was built to be exactly that — a platform that gives trial teams complete, documented social media intelligence on every prospective juror in their pool, without the ethical exposure that comes with doing it manually. See how it works here.
