What Are the Main Defenses to a TCPA Lawsuit?

Short Answer

The main defenses to a TCPA lawsuit depend on the statutory theory and facts actually pleaded. Potential defenses can include ATDS functionality, artificial or prerecorded voice allegations, consent and revocation, telephone-solicitation status, the number of contacts, Do-Not-Call eligibility, reasonable compliance procedures, standing, limitations, direct liability, agency or ratification, and class-certification defenses.

Expanded Answer

A TCPA complaint should be separated by statutory subsection before the company chooses its defense. Section 227(b) and Section 227(c)(5) regulate different conduct and do not necessarily require the same proof.

Klemchuk’s In-Depth Guide, “How Should a Company Defend a TCPA Lawsuit in the Northern District of Texas?”, recommends mapping each count to its statutory elements and then investigating the communications, technology, consent history, number and timing of contacts, purpose, called-number status, and third-party relationships that matter to that claim. For the broader NDTX defense context, see Klemchuk’s Ideate article, Defending TCPA Lawsuits in the Northern District of Texas: Claims, Defenses & Damages [ADD LIVE LINK].

Technology can be a threshold issue after Facebook, Inc. v. Duguid. If the plaintiff alleges an ATDS, the company should identify the actual platform, how numbers entered the system, and the relevant functionality rather than accept a generalized allegation that the communications were automated.

Consent, vendor relationships, and compliance procedures can also materially affect the defense. Consent records may bear on individual liability and class certification. Vendor conduct can raise direct and vicarious liability and contractual risk-transfer issues.

No single checklist determines the outcome. The useful framework is to identify the statutory theory first, preserve the evidence tied to that theory, and evaluate merits, procedural defenses, contractual rights, and class exposure together.

Practical Considerations

At the beginning of a TCPA case, preserve call and text logs, consent and opt-out records, platform information, campaign data, lead-source records, vendor agreements, and compliance materials.

For an enterprise defendant, insurance, indemnification, vendor obligations, potential class size, and the data needed to address Rule 23 should be evaluated early.
