One of the most important — and most heavily litigated — issues in TCPA cases is not whether unlawful calls were made. In many cases, that part is relatively straightforward. The real battleground is attribution: who is legally responsible for those calls?
In today’s telemarketing ecosystem, the entity placing the call is often several steps removed from the entity benefiting from it. Sellers rely on layers of marketers, affiliates, lead generators, and call centers — creating distance that is then weaponized in litigation.
That is why vicarious liability is not just a legal theory in TCPA cases — it is the backbone of meaningful enforcement.
From a plaintiff’s perspective, building a strong vicarious liability argument requires more than citing agency law. It requires developing a factual record that demonstrates control, benefit, and connection between the caller and the seller. When done correctly, it transforms a case from “wrong number dialed by a rogue actor” into “systematic telemarketing conducted for the defendant’s benefit.”
Here is how that is done.
UNDERSTAND THE LEGAL FRAMEWORK — BUT DON’T STOP THERE
The FCC has made clear that sellers may be held liable under federal common law agency principles, including:
• Actual authority
• Apparent authority
• Ratification
Most defense arguments focus on narrowing these doctrines — emphasizing lack of direct control, contractual disclaimers, or independent contractor relationships.
But courts consistently look beyond labels.
The key is not what the contract says — it is how the relationship actually functions.
A strong plaintiff-side argument starts by recognizing that these agency theories are flexible and fact-driven. The goal is to develop evidence that fits within multiple theories simultaneously, rather than relying on just one.
CONTROL: THE MOST MISUNDERSTOOD FACTOR
Defendants often argue that they lack control because they do not physically place the calls or directly supervise the dialers.
But control, in the agency context, is broader than that.
It includes:
• Setting marketing guidelines or scripts
• Requiring compliance with brand standards
• Approving or rejecting marketing partners
• Dictating how leads are generated or transferred
• Monitoring performance metrics
• Retaining the right to terminate relationships
Even indirect control can be sufficient.
Plaintiffs should focus discovery on uncovering how the seller influences the telemarketing process — not just whether it pushes the “dial” button.
For example:
Did the defendant provide approved language?
Did it require certain disclosures?
Did it control how leads were delivered?
Each of these facts supports an inference of control.
APPARENT AUTHORITY: WHAT THE CONSUMER EXPERIENCED
Apparent authority is often one of the most powerful — and underutilized — tools in TCPA litigation.
The question is simple: would a reasonable consumer believe the caller was acting on behalf of the defendant?
This shifts the focus from internal contracts to external reality.
Evidence supporting apparent authority includes:
• Use of the defendant’s name, products, or services during the call
• References to prior inquiries or applications tied to the defendant
• Transfers to representatives associated with the defendant
• Follow-up communications branded with the defendant’s identity
Plaintiff testimony is critical here.
Consumers can describe what they were told, what they believed, and why they associated the call with a particular company.
When multiple plaintiffs report similar experiences, the argument becomes even stronger.
Because at that point, it is no longer anecdotal — it is a pattern.
RATIFICATION: FOLLOW THE MONEY
Ratification focuses on what the defendant did after the calls were made.
Did the company accept the benefits of the telemarketing?
If the answer is yes, liability becomes significantly easier to establish.
Key evidence includes:
• Payments for leads generated through telemarketing
• Revenue derived from customers obtained through those leads
• Failure to investigate or stop unlawful practices
• Continued relationships with known violators
This is where financial discovery becomes critical.
If a company is paying for leads, and those leads are generated through unlawful calls, the defendant cannot simply look the other way.
Courts have repeatedly held that accepting the benefits of unlawful conduct — especially with knowledge or willful blindness — supports ratification.
In practice, this often becomes one of the strongest plaintiff arguments.
Because money leaves a trail.
BUILDING THE FACTUAL RECORD: START EARLY
Strong vicarious liability arguments are not built at summary judgment. They are built from day one.
Everything begins with intake.
Plaintiff firms should prioritize collecting detailed information about:
• The content of the call
• The identity (or claimed identity) of the caller
• Any transfers or follow-up communications
• Phone numbers used
• Timing and frequency of calls
• Any resulting transactions or applications
This information becomes the foundation for later discovery.
It also allows counsel to identify patterns across multiple plaintiffs — which is often the key to tying calls back to a seller.
Once litigation begins, discovery should be targeted and strategic.
Focus on:
• Contracts between the defendant and marketing partners
• Lead purchase agreements
• Call center relationships
• Compliance policies and enforcement mechanisms
• Internal communications about telemarketing practices
• Data showing how leads are generated, tracked, and monetized
The goal is not just to obtain documents — it is to map the ecosystem.
CONNECTING THE DOTS: PATTERN EVIDENCE MATTERS
One of the most effective ways to strengthen vicarious liability arguments is through pattern evidence.
A single call may be easy for a defendant to dismiss.
Dozens — or hundreds — of similar calls are not.
By aggregating data across plaintiffs, attorneys can demonstrate:
• Consistent scripts or messaging
• Repeated use of certain phone numbers
• Identical transfer pathways
• Uniform products or services being marketed
This type of evidence undermines the “rogue actor” defense.
It shows that the calls were part of a coordinated campaign — one that ultimately benefits the defendant.
And importantly, it makes it much harder for defendants to claim lack of knowledge.
Because patterns imply system, not accident.
ATTACKING THE INDEPENDENT CONTRACTOR DEFENSE
One of the most common defenses in TCPA cases is the assertion that the caller was an independent contractor.
But this is not a silver bullet.
Courts have made clear that:
• Agency relationships can exist even with independent contractors
• Labels in contracts are not determinative
• The actual conduct of the parties controls
Plaintiffs should focus on exposing inconsistencies between the defendant’s contractual language and real-world practices.
For example:
Does the defendant claim no control, yet provide detailed marketing guidelines?
Does it deny involvement, yet track and optimize lead performance?
Does it disclaim responsibility, yet profit directly from the calls?
These contradictions are powerful.
They show that the independent contractor label is often more about liability avoidance than operational reality.
LEVERAGING TECHNOLOGY AND DATA
Modern TCPA litigation increasingly relies on data.
Call logs, dialing records, CRM systems, and lead tracking platforms can all provide critical evidence.
Plaintiffs should seek:
• Call detail records linking numbers to campaigns
• Vendor databases showing lead sources
• Internal dashboards tracking conversion rates
• Metadata connecting calls to specific marketing partners
In many cases, this data reveals connections that are not obvious from contracts alone.
It can show, for example, that:
• Specific vendors consistently generate leads for the defendant
• Certain campaigns produce high volumes of calls
• The defendant actively monitors and rewards those campaigns
This type of evidence goes directly to control and ratification.
And it is often difficult for defendants to explain away.
THE IMPORTANCE OF NARRATIVE
At the end of the day, vicarious liability is not just about legal elements — it is about telling a compelling story.
A strong plaintiff narrative might look like this:
The defendant wanted more customers.
It engaged a network of marketers to generate leads.
Those marketers used unlawful robocalls and texts.
The defendant benefited from those calls.
And despite knowing (or having reason to know) what was happening, it allowed the conduct to continue.
This narrative resonates because it aligns with common sense.
Companies should not be allowed to outsource illegal conduct and then disclaim responsibility while keeping the profits.
The more your evidence supports this story, the stronger your case becomes.
ANTICIPATING DEFENSE STRATEGIES
Defendants will attempt to:
• Isolate each call as a standalone घटना
• Emphasize contractual disclaimers
• Shift blame to third parties
• Argue lack of knowledge
Plaintiffs should be prepared to counter each of these arguments with evidence showing:
• Systematic conduct, not isolated incidents
• Real-world control, not just contractual language
• Financial benefit and ongoing relationships
• Patterns that imply knowledge or willful blindness
Preparation is key.
Because the strength of a vicarious liability argument often determines the outcome of the case.
FINAL THOUGHT
TCPA enforcement depends on the ability to hold the right parties accountable.
If liability stopped at the dialer, the statute would be easily circumvented:
Outsource the calls.
Deny involvement.
Keep the revenue.
Vicarious liability prevents that outcome.
But it does not establish itself.
It must be built — piece by piece — through careful intake, strategic discovery, and thoughtful presentation.
For plaintiff-side practitioners, the goal is clear:
Connect the call to the campaign.
Connect the campaign to the defendant.
And show that the defendant controlled, benefited from, or ratified the conduct.
Do that effectively, and the argument becomes not just legally sound — but unavoidable.
And that is when TCPA litigation fulfills its purpose:
Not just compensating consumers,
But deterring the very systems that created the harm in the first place.
