California has enacted Senate Bill 690 (SB 690) to block the torrent of demand letters and lawsuits alleging that websites have violated a California Invasion of Privacy Act (CIPA) provision covering pen register devices.
SB 690, which applies retroactively to cases filed in 2025 or after, would affect 27 percent of CIPA cases, according to the CIPA Reform coalition. The amendment “has the unintended effect of removing the claim that was easiest to plead but most difficult for plaintiffs to justify as a concrete injury,” Baker Donelson of counsel David Oberly told the Cybersecurity and AI Law Report.
While it eliminates one category of CIPA claims, SB 690 preserves the law’s wiretapping and eavesdropping causes of action, but 2026 court decisions are raising the pleading burden on those remaining theories. Over a dozen judicial decisions between July and September 2026 have set some clearer dividing lines for what counts as a concrete privacy injury that allows cases to advance.
This article, with insights from Oberly and litigation parters at Duane Morris and Manatt, examines how SB 690 may alter the CIPA litigation landscape; reviews 2026 court decisions that are drawing clearer lines on standing, consent and class certification; and provides practical guidance for mitigating litigation and regulatory risk.

SB 690’s Dual Impact
The amendment to CIPA removes only one cause of action, which will refocus court arguments and settlement negotiations.
Plaintiffs’ Focus Shifts to Wiretapping and Eavesdropping Claims
SB 690 prohibits private lawsuits that allege a Section 638.51 violation – the statute’s pen register and trap-and-trace provision – arising from conduct occurring on an “internet website, online application, or mobile application.” From April 2025 to July 2026, the number of filed cases with these claims jumped from 600 to 4,000, according to the sponsoring assemblymember.
The pen register cases have flourished because plaintiffs can start a lawsuit quickly and without much investigation. A person can allegedly acquire a claim “within milliseconds because it is collecting browser and device information” before the user consents, Duane Morris partner Colin Knisely told the Cybersecurity and AI Law Report. The plaintiffs’ claim is based on the theory that collecting metadata through web cookies, pixels, software development kits and other trackers is the same as tracing telephone digits dialed, the original focus of this 1967 law section.
The courts are jammed with CIPA cases because plaintiffs’ attorneys have decided they can target any website that in good faith uses widely available and standard tools, like analytics or cybersecurity software, despite adhering to the CCPA, Knisely explained. Plaintiffs also see opportunity in courts’ differing interpretations of how Section 638.51 applies to websites.
“SB 690 gives plaintiffs’ attorneys one less avenue for exerting leverage, which is good for defendants” and may reduce the burden of combatting the nuisance demands, Manatt partner Brandon Reilly told the Cybersecurity and AI Law Report. CIPA’s wiretapping and eavesdropping laws require plaintiffs to make more substantial arguments to prove the defendant accessed the “contents of a communication,” he noted.
As legislators introduced the reform in 2025, “a lot of firms have already been broadening their claims,” Knisely reported. “I don’t expect the demand letters to slow down,” or many plaintiffs’ firms “to walk away from the money train,” he said.
Companies’ Risk Expands to California Regulators
While it reduces exposure to private litigation, SB 690 increases regulatory risk for companies. The amendment shifts enforcement of Section 638.51 to the California AG, with penalties of $5,000 per occurrence remaining without the need to show actual damages.
“Both the AG and CalPrivacy have spent much of the last two years policing exactly the conduct at issue in digital privacy and web tracking disputes – including cookie banners that don’t disable tracking cookies despite purporting to do so, consumer opt-outs, and missteps regarding adherence to data minimization and purpose limitation obligations,” Oberly noted.
Legislators also gave the California AG an enforcement boost, granting it a budget of up to $1.5 million and providing for the addition of six DOJ positions for SB 690 enforcement. Private litigants will continue pursuing CIPA cases under other theories, but “regulators’ leverage on the same facts has increased by a significant margin,” Oberly cautioned.

Emerging Dividing Lines in CIPA Disputes
Court decisions are drawing clearer lines around three recurring issues in CIPA litigation: standing, consent and class certification. The decisions discussed below illustrate how judges are approaching each question.
Standing
As evidenced by 2026 decisions, courts are converging on two primary standing questions in web tracking class actions: whether the disclosed information was sufficiently sensitive, and whether plaintiffs plausibly alleged they were personally tracked.
Generalized Tracking Allegations Fall Short
Under constitutional principles of standing, plaintiffs must allege a concrete privacy injury to bring a federal action. Article III standing decisions have been encouraging for defendants, with federal judges increasingly finding no actual injury from digital tracking, Reilly observed.
In California federal courts, standing disputes are largely governed by Popa v. Microsoft Corp., in which the U.S. Court of Appeals for the Ninth Circuit held that generalized allegations of injury from web tracking are constitutionally insufficient to confer standing. Where trackers gather routine website interaction data like mouse movements, clicks or URLs visited, the collection is more akin to “a store clerk’s observing shoppers in order to identify aisles that are particularly popular or to spot problems that disrupt potential sales” than to an actionable intrusion, the Popa court reasoned.
See “Will Supreme Court’s New Standing Test Tame the Real World of Class Actions?” (Jul. 28, 2021).
Data Sensitivity Required to Establish Privacy Injury
In April 2026, the U.S. District Court for the Central District of California dismissed a lawsuit against Blackhawk Networks for failure to allege a sufficient injury. The lead plaintiff alleged that two dozen advertising trackers fired on her site visit despite her having selected “required only” cookies. The court cited Popa in dismissing the case, holding that the plaintiff did not, as required, “allege facts that indicate: (1) Defendant used tracking technologies that collected especially sensitive or wide-reaching information; and (2) those tracking technologies were actually installed on Plaintiff’s computer.”
In subsequent 2026 rulings, courts have continued to focus on the sensitivity of data shared with third parties without consent. “District court decisions [in summer 2026] in Zeta Global, Magliocca, Rack Room Shoes and Felsen provide a clear dividing line: the sharing of single-site retail browsing, IP addresses, device data and email addresses” does not give rise to an actionable injury, Oberly observed. In contrast, an injury can arise from sharing “full financial card numbers, authenticated financial activity, and cross-site ‘cradle-to-grave’ profiles,” he explained.
In Zeta Global, a Southern District of New York court dismissed the suit because the complaint alleged disclosure of the plaintiffs’ PII without specifying the categories of data that were shared beyond email address, browser information and “campaign identifiers.” The court held that this information does not constitute the sensitive information needed to plead a cognizable privacy injury.
Many wiretapping cases around the country target healthcare entities. The U.S. District Court for the Eastern District of California’s August 2026 decision in Magliocca v. United Healthcare provided strong support for defendants in these cases, Oberly opined. In Magliocca, the plaintiff alleged that she was tracked when she browsed Medicare plans on its website. The court held that such information does not “reflexively” become private because the operator is a health insurer, unlike information about health conditions. Nor does an age-related inference create the “cradle-to-grave profile” of sensitive information that the Ninth Circuit requires for a concrete injury. The Magliocca finding shows how the Popa standing framework “can shut down even healthcare-related class actions at the threshold,” he said.
In contrast, a Pennsylvania federal court in Felsen found standing in September 2026, holding that Vanguard’s sharing of the plaintiffs’ investment-related website activity involved sufficiently sensitive information to constitute a privacy injury.
See “Litigation Landscape for Cookie and Tracking Technology Claims Brought Under Federal Privacy Statutes” (Jan. 21, 2026).
Plaintiffs Must Demonstrate They Were Actually Tracked
Multiple courts have held that plaintiffs must show that tracking technologies were installed on their own devices. In July 2026, a Northern District of California court rejected standing in Barrales v Reckitt Benckiser because the complaint lacked details about the named plaintiffs’ own website experiences. “Most of the allegations are framed in terms of the collective class experience or the experience of a composite consumer,” the court noted.
The Zeta Global court similarly noted “that speculation about what a defendant ‘likely’ collected cannot support standing,” Knisely said.
Other courts have permitted plaintiffs to provide only broader details showing they were likely tracked. In September 2026, in D’Antonio v. Smith & Wesson Inc., a different Northern District California court rejected defendants’ argument that the allegations had to specify individual cookies and transmissions going to named third parties. “Smith & Wesson reads a level of specificity into the pleading requirements that is unrealistic,” the court stated, rejecting the company’s motion to dismiss.
See our four-part series on tracking technologies: “Privacy Regulation, Enforcement and Risk” (Jan. 17, 2024), “A Deep Dive on What They Are and How They Work” (Jan. 31, 2024), “A 360‑Degree Governance Plan” (Feb. 21, 2024), and “Compliance Challenges and Solutions” (Apr. 17, 2024).
Detailed Allegations Can Survive Dismissal
Complaints are becoming more detailed. “Plaintiffs almost all include screenshots now. They also may attach a HAR (HTTP Archive) report,” which records browser interactions in detail, Knisely observed. With plaintiffs providing more technical support for their allegations, defendants’ IT departments or web developers should check the accuracy of complaints. “Sometimes we’ll bring in experts from the outside to give a better idea of what plaintiffs might be seeing in their scanning,” he shared.
That increased specificity is already influencing courts’ standing analyses. The Northern District of California court in Briskin v. Shopify held for the plaintiffs because they offered enough concrete details about the website’s data processing, Knisely noted. “Expect well-pleaded complaints with specific, nonconclusory factual allegations to survive dismissal,” he cautioned. Although the court in Briskin held that issues requiring an evidentiary record should be addressed on summary judgment, defendants should still challenge whether plaintiffs have pleaded specific facts supporting each theory of harm, he advised.
Detailed allegations alone, however, will not necessarily survive a motion to dismiss. The data shared still must be sensitive, Oberly stressed. The plaintiff in Magliocca, for example, alleged that United Health deployed “155 third-party trackers, including 47 cookies, 19 different canvas fingerprints and one session recorder” from a host of vendors, and tracked at least 12 categories of information, including ZIP code location, persistent identifiers and the plaintiff’s journey through the website. Defendants argued that none of the data tracked was sufficiently sensitive. The court agreed and dismissed the lawsuit.

Consent
The adequacy of consent remains a central issue in wiretap litigation. Two 2026 Northern District of California cases illustrate the dividing line for consent, Oberly highlighted. If a user validly consents to the collection or sharing of data, it “is a complete defense to most causes of action asserted in digital privacy and web tracking class disputes,” he pointed out. “Consent must be three things – prior, affirmative and technically enforced,” he added. In re Adobe, a September 2026 ruling, provides the stronger precedent for defendants, holding that a plaintiff must plead facts that show lack of consent. “According to the court, ‘the internet is not a place where users have a reasonable expectation of privacy,’” he noted.
Two weeks earlier, in finding for the plaintiffs, the court in Asercion v. Ulta held that the existence of a privacy policy cannot serve as consent when trackers fire the instant that a page loads and before any user could see the policy. The court in Felsen similarly held that a privacy policy buried in a footer link does not constitute consent. When a site’s banner does not block the firing of trackers until after the user has completed the consent process, plaintiffs may cite that as evidence that consent was not obtained, Oberly noted.
See “Cookie Compliance Strategies for 2026” (Apr. 15, 2026).
Class Certification
Class certification has emerged as another key battleground in CIPA litigation, with courts closely scrutinizing whether individualized issues predominate over common questions.
In July 2026, the U.S. District Court for the Central District of California delivered a defense victory on class certification in Lewis v. Magnite, Knisely highlighted. The court in Lewis denied certification because determining whether a tracking ID was set required an individualized, technical inquiry. The answer varied based on each user’s browser, device, privacy settings and page configuration, making it difficult to resolve key issues through common evidence applicable to the entire class, the court concluded.
The Lewis ruling underscores that defendants may still have a class certification argument even if a case survives dismissal. To support that argument, companies should consider presenting expert evidence early in the pleading phase that class membership cannot be determined through common proof, Knisely advised.
Compliance Steps
The following measures incorporate lessons from SB 690, 2026 case law and web-tracking litigation in other states – like Florida, Pennsylvania, Michigan and Massachusetts – to help companies reduce litigation and regulatory risk and strengthen potential defense.
See our two-part series on CCPA private actions after the CPRA: “Key Issues and Defense Strategies” (Oct. 18, 2023), and “Settlement Considerations and Mitigating Risk” (Oct. 25, 2023).
Inventory Tracking Technologies
It is important for companies to determine what each tracker collects, who receives the data and when it fires relative to consent. Companies can use this inventory to write detailed and accurate disclosures and confirm no mismatch occurs between disclosures and actual practices, Oberly said.
Gate the Firing of Trackers
Companies should engineer their consent management platforms (CMPs) to block non-essential pixels, cookies and tags until the visitor sees the disclosures and clicks to consent. Engineers and compliance teams can verify the suppression work through HTTP records, Knisely suggested.
Additionally, “consent events should be logged with timestamps and language version,” Oberly advised.
See “Practical Strategies for Effective Consent Management” (Sep. 25, 2024).
Audit and Revise Notices and Disclosures
Companies should “align words and wires – privacy policies, cookie notices, banner text and CCPA Do Not Sell/Share Links must describe what actually happens,” Oberly warned. Misalignment could lead to claims under consumer fraud laws, he added. When drafting policies, it is good practice to assume regulators will be quoting the language in an action. Companies’ disclosures about third parties need to name specific third parties where possible, and list data categories and purposes for which the third party uses the data, he advised.
The updated disclosures must require a click or other affirmative interaction with a banner or box that details the third-party sharing, Oberly recommended. Companies should not rely solely on footer links to provide notice. With state regulators, the FTC and plaintiffs’ attorneys increasingly scrutinizing tracking practices, and new California opt-out requirements taking effect in 2027, companies’ records should include versions of notices and banners, logs of changes and enough detail to offer proof of compliance, he said.
Separate the Sensitive Data
Companies should consider “quarantining sensitive surfaces. No third-party marketing tags” should attach to that data, Oberly urged. Contractual limits on vendors’ use of sensitive data should complement those technical controls, he added.
Alternatively, for areas that collect sensitive data, such as authenticated sessions involving financial data, companies should strictly enforce a policy of using only first-party tags. They also should consider converting to “server-side tagging,” which routes the user interaction through a company server to help ensure that only necessary and compliant data is shared with third-party services.
See “Roadmap for Building an Efficient Global Privacy Program: Organizational Structure” (May 4, 2022).
Minimize Data
“A good rule of thumb is: data that is never collected cannot support a claim,” Oberly offered. Companies can further their minimization by imposing retention limits, using hashed identifiers and applying restricted data processing modes.
Augment Vendor Contracts
Companies’ contracts with vendors should include appropriate data-sharing terms, such as restrictions on vendors’ use of data for their own purposes, Oberly advised, noting those provisions can help support the party exception defense to wiretapping claims.
Companies also should require vendors to implement “pre-consent suppression” for processing and honor global privacy control signals.
Preserve Records for Enforcement and Litigation
Companies should assume that the California AG’s investigations under CIPA Section 638.51, now supported by funding under SB 690, will “look the same as CCPA investigations,” Oberly suggested. “Opt-out logs, tracker audits and risk assessments are key” pieces of evidence, he noted.
Companies with robust recordkeeping have been able to prevent litigation before it begins, by supplying evidence to respond to demand letters, likely driving plaintiffs’ attorneys to move on to another company, Oberly observed.
To establish records in advance of needing to defend a wiretap lawsuit, companies should preserve all versions of their opt-out banners, CMP logs and configurations of tag managers. Documenting “variation in the privacy disclosures encountered by different putative class members” can combat certification, Knisely offered, referencing the Lewis court “finding that individualized issues of cookie identification, consent and standing predominate over common questions in tracking technology cases,” he explained.
Update Playbook for Demand Letters
Companies should set a policy of calling counsel within 72 hours of receiving a demand letter, Oberly advised. Response protocols also should be updated to reflect the changing litigation landscape, with less emphasis on pen register claims and greater attention to allegations involving sensitive data.
As a final step, companies should create procedures and designate internal owners for producing consent records on short notice.
