Court Certifies TCPA Class Action in Unsolicited Fax Case

Just when you thought unsolicited fax litigation had shuffled off to the same dusty shelf as floppy disks and dial-up tones, a federal court reminded everyone that the junk-fax era still has teeth. And not tiny teeth either. The kind that can chew through a defendant’s budget one $500 statutory penalty at a time.

The headline issue is simple: a court certified a TCPA class action in an unsolicited fax case, allowing the plaintiffs to pursue claims on behalf of a larger group instead of slogging through hundreds or thousands of one-off disputes. In plain English, that is a big deal. Class certification is often the moment when a routine lawsuit turns into a full-blown legal migraine.

For businesses, healthcare providers, marketers, and anyone who still thinks fax outreach is a harmless throwback tactic, this ruling is a useful warning shot. For plaintiffs’ lawyers, it is a reminder that fax cases are not dead. They are merely sitting quietly in the corner, waiting for someone to hit “send all.”

What Happened in the Unsolicited Fax Case?

The case most closely tied to this headline is Douglas Phillip Brust, D.C., P.C. v. Opensided MRI of St. Louis, LLC, a federal case out of Missouri. The plaintiffs alleged that Opensided MRI sent a series of unsolicited fax advertisements to members of the St. Louis medical community during the early months of the COVID-19 pandemic. According to the court record, the faxes promoted the imaging center’s services and emphasized that it remained open while other radiology providers were closed.

That factual setup matters because the Telephone Consumer Protection Act, or TCPA, sharply restricts unsolicited fax advertisements. The statute allows private plaintiffs to seek either actual damages or statutory damages of $500 per violation, with the possibility of treble damages for willful or knowing misconduct. Suddenly, what looked like a marketing campaign can start to resemble a math problem from a very expensive law school exam.

In the Missouri case, the court noted allegations that 7,522 fax advertisements were sent to about 1,583 fax numbers over five dates in spring 2020. That kind of volume is exactly why class actions show up in TCPA litigation. One fax may be annoying. Thousands of them can become headline material.

Why the Court Certified the TCPA Class

Class certification does not decide whether the defendant ultimately violated the law. It decides whether the case can proceed on a representative basis under Rule 23 of the Federal Rules of Civil Procedure. That rule requires a proposed class to satisfy familiar requirements such as numerosity, commonality, typicality, and adequacy, and for a damages class, common issues must predominate over individual ones.

Here, the Missouri federal court concluded that the proposed class cleared those hurdles. Numerosity was not exactly a close call. When a case involves more than 1,500 alleged recipients, joinder is not practical unless someone has discovered teleportation for court filings.

The court also found common issues that could be resolved across the class. Those included whether the faxes were advertisements, whether they were unsolicited, whether the defendant was the sender, and whether the campaign followed a common course of conduct. In a junk-fax case, those are the kinds of questions that make or break class treatment. If the answers depend heavily on one unified fax blast rather than dozens of individualized conversations, plaintiffs have a much better shot at certification.

Perhaps most importantly, the court found predominance and superiority. That is the legal way of saying the common issues mattered more than any individualized ones and that a class action made more sense than forcing everyone to sue separately for relatively small statutory amounts. That logic is common in TCPA cases. A $500 claim is real money, but it is rarely enough to make a solo federal lawsuit attractive. Bundle enough of those claims together, though, and the courtroom suddenly gets crowded.

The Online Fax Problem That Keeps Haunting TCPA Cases

Now for the twist that makes fax litigation weirdly technical: not every fax is really a “fax” for TCPA purposes in the modern sense. Some recipients use traditional machines that print onto paper. Others receive fax transmissions through online fax services, where the message lands more like an email attachment than a sheet spit out by a humming office dinosaur.

That distinction has become a major fault line in unsolicited fax litigation. In 2019, the FCC issued the Amerifactors declaratory ruling stating that an online fax service is not a “telephone facsimile machine” under the TCPA. That ruling gave defendants a valuable argument: if a message was received through an online fax service rather than a traditional machine, maybe the TCPA’s junk-fax ban did not apply.

In the Missouri case, the defense raised exactly that argument. One named plaintiff allegedly received the fax on a traditional machine, while another allegedly received it via an online fax service. The court still certified a class, effectively rejecting the idea that online fax issues defeated certification in that case. At the time, the court leaned in part on authority such as the Sixth Circuit’s decision in Lyngaas v. Curaden AG, which had taken a broader view of fax liability.

That made the certification ruling notable. The court was not persuaded that the online-fax wrinkle automatically destroyed standing, predominance, or class cohesion. Instead, it allowed the case to proceed as a certified class action.

Why This TCPA Fax Ruling Still Matters After Later Cases

Legal stories rarely stay frozen in amber, and unsolicited fax law has changed in important ways since that Missouri certification order. That is precisely why this topic remains interesting for SEO readers, compliance teams, and litigators alike.

1. The Supreme Court Shook the Ground Beneath TCPA Cases

In 2025, the U.S. Supreme Court decided McLaughlin Chiropractic Associates, Inc. v. McKesson Corp. The Court held that district courts are not automatically bound by the FCC’s legal interpretation of the TCPA under the Hobbs Act. Translation: lower courts now have more room to interpret the statute themselves instead of simply saluting whatever the FCC previously said.

That is huge for junk-fax litigation. Before McLaughlin, litigants often treated FCC interpretations as highly controlling. After McLaughlin, the picture is messier. Some courts may still find the FCC’s reasoning persuasive. Others may not. If you enjoy certainty, this was not your favorite Supreme Court opinion.

2. Other Courts Have Refused to Certify TCPA Fax Classes

The Missouri certification ruling did not create a one-size-fits-all rule. Quite the opposite. Other courts have refused to certify unsolicited fax classes where individual issues became too dominant.

For example, the Fourth Circuit in Career Counseling, Inc. v. Amerifactors Financial Group, LLC upheld denial of class certification where the plaintiff could not readily identify which recipients used traditional fax machines versus online fax services. That ascertainability problem mattered because eligibility for recovery depended on how the fax was received.

Likewise, the Third Circuit in early 2025 affirmed denial of class certification in a case against Fox Rehabilitation, finding that questions of consent would require too many individualized inquiries. That is another reminder that class certification in TCPA litigation often turns less on the statute itself and more on whether the evidence can be handled in one big package rather than thousands of mini-trials.

3. Fax Cases Are Narrower Than They Look, but Still Dangerous

These recent decisions tell a consistent story: TCPA unsolicited fax claims are still viable, but certification depends heavily on the facts. A single mass fax campaign with common proof may support class treatment. A messy record involving individualized consent, uncertain recipient equipment, or disputed sending methods may sink it.

So yes, the court certifying a TCPA class action in an unsolicited fax case is important. But the bigger lesson is not “plaintiffs always win certification” or “defendants can always knock it out with online-fax arguments.” The real lesson is that these cases are becoming increasingly fact-sensitive and strategically complex.

What Counts as an Unsolicited Fax Advertisement?

Under the TCPA, the issue is not simply whether a fax was sent. It is whether an unsolicited advertisement was sent to a telephone facsimile machine without satisfying the law’s requirements. That seems straightforward until litigants start arguing about what counts as an advertisement, whether the recipient gave prior express invitation or permission, whether an established business relationship existed, and whether the required opt-out notice appeared in the right form.

That is why healthcare-related fax cases show up so often. Healthcare businesses often send informational material, appointment reminders, surveys, referral communications, and service announcements. Somewhere between “helpful update” and “please buy our thing,” a fax can cross the line into advertisement territory.

The Missouri case reflects that gray area. A message announcing that an imaging center was open and touting its services during a period of market disruption may sound practical on one level. On another, it can look very much like classic marketing. Courts examine the content, purpose, and context, not just the sender’s self-serving label.

Why Businesses Should Pay Attention Right Now

If you run a business and still use fax-based outreach, the practical takeaway is not subtle: audit that process immediately. Fax marketing is one of those old-school habits that survives in niche industries long after everyone assumes it has gone extinct. Healthcare, legal, insurance, finance, and certain B2B sectors still lean on fax workflows more than the average smartphone-saturated consumer might expect.

That creates risk in at least three ways. First, old recipient lists can be stale, inherited, or poorly documented. Second, companies may not know whether they are dealing with traditional machines or online fax services. Third, teams often assume that because a communication feels industry-specific or business-to-business, it must be safe. The TCPA has a marvelous habit of punishing that assumption.

Smart compliance now means documenting consent, reviewing opt-out language, distinguishing informational communications from advertisements, checking vendor practices, and keeping records that can actually survive discovery. Because once a case reaches the class-certification stage, “we thought it was fine” is not exactly a premium defense strategy.

Practical Lessons for Plaintiffs and Defendants

For Plaintiffs

Plaintiffs need a class definition that matches the available proof. If the class includes people who may have received faxes through noncovered methods, defendants will attack ascertainability, standing, and predominance. If consent varies wildly, certification becomes much harder. The cleanest fax cases are the ones built around a discrete campaign, common content, uniform transmission records, and minimal individualized defenses.

For Defendants

Defendants should focus early on consent evidence, the nature of the equipment used by recipients, and whether the fax was truly promotional. They should also evaluate whether the FCC’s earlier interpretations remain persuasive after McLaughlin. The days of relying on regulatory gravity alone are over. Courts may now engage more directly with the statutory text, which means briefing quality matters more than ever.

Experience From the Real World of Junk Fax Litigation

In practice, unsolicited fax cases often begin in the least cinematic way possible. No one slams a phone. No one dramatically gasps. Instead, someone in an office notices a weird promotional fax, shrugs, and tosses it aside. Then someone else notices the same fax. Then a lawyer notices a pattern. Suddenly, a marketing experiment from years ago has become a federal class action with commas in all the wrong places.

One of the most common real-world experiences tied to these cases is poor recordkeeping. Businesses frequently inherit fax lists from prior vendors, sales reps, old acquisitions, or office staff who have long since moved on. By the time litigation begins, the company may know that faxes were sent, but not precisely why a given number was on the list, whether permission was ever granted, or whether the recipient used a paper machine, a fax server, or an online service. That gap between “we sent something” and “we can prove we were allowed to send it” is where trouble loves to live.

Another familiar experience is the mismatch between operational reality and legal assumptions. A business team may view a fax as a quick professional update: a reminder that services are available, a notice about hours, a product announcement, or a referral option. Legal analysis, however, asks a colder question: was this an advertisement? If the message promotes commercially available goods or services, even with a polite tone and professional formatting, courts may see it as marketing in a necktie.

Healthcare providers, in particular, have learned this the hard way. Offices still use fax because the industry never fully broke up with it. Referrals, records, scheduling, and vendor communications all pass through the same channel. That makes it dangerously easy for promotional content to travel through a system everyone treats as routine. A fax can feel ordinary inside the office and still be actionable inside a complaint.

There is also a human experience on the recipient side that courts do not entirely ignore. Even when the cost per fax seems tiny, recipients often describe the same irritation: interrupted workflow, wasted staff time, cluttered systems, and one more unwanted commercial message inserted into a business day that was already doing too much. The law’s concern has always been about more than paper and toner. It is also about shifting the burden of marketing onto the recipient.

And then there is the settlement pressure. Once a class is certified, defendants often experience a very abrupt change in mood. A case that looked manageable as a dispute over a handful of faxes starts to carry aggregate exposure that can reshape litigation strategy overnight. That is why class certification remains the hinge point. It changes the conversation from “did we send this?” to “what is our total exposure if a jury dislikes the answer?”

The strongest lesson from real-world TCPA fax experience is brutally simple: old technology still creates modern liability. Fax marketing may feel quaint, but in court it is not quaint at all. It is a statutory regime with sharp penalties, evolving case law, and very little patience for sloppy compliance.

Conclusion

The phrase “court certifies TCPA class action in unsolicited fax case” may sound niche, but it captures a larger truth about modern compliance litigation. Legacy communication tools still create real legal exposure. A single fax campaign can become a class action. A seemingly narrow procedural ruling can determine whether a defendant faces a modest dispute or a bet-the-case fight.

The Missouri ruling shows that plaintiffs can still win certification in the right unsolicited fax case, especially where the alleged campaign is uniform and the proof is common. But later decisions from other courts, along with the Supreme Court’s McLaughlin opinion, also show that this area of law is getting more complicated, not less. Consent, ascertainability, equipment type, and statutory interpretation all matter. A lot.

So no, the fax machine is not exactly cool again. But from a litigation standpoint, it remains surprisingly influential. And if your company still uses it for promotions, now would be an excellent time to make sure your compliance strategy is more modern than your office hardware.
