Mobile Phone Radiation Litigation
Mobile phone radiation litigation has involved manufacturers, employers, occupational compensation authorities and regulatory institutions in several countries. The proceedings have addressed different questions, including alleged product-safety failures, consumer information, occupational health, the admissibility of scientific evidence and access to regulatory documents.
This article examines selected cases and legal developments, outlining the allegations, relevant court decisions and reported procedural outcomes. It distinguishes claims made by the parties from judicial findings and identifies where the available information does not establish a case’s final status.
Claims Against Manufacturers
1. In re Wireless Telephone Radio Frequency Emissions Products Liability Litigation
United States | 2001–2006 | Consolidated proceedings involving five class actions
Issue: Could mobile phone manufacturers face state-law claims over alleged health risks associated with radiofrequency (RF) emissions?
Five class actions were filed in different states. The court consolidated the cases for pretrial proceedings in a federal court in Maryland.
The plaintiffs alleged that RF emissions from mobile phones posed health risks and that manufacturers had failed to provide adequate protection or warnings.
In 2003, the federal district court dismissed the five cases on the basis of implied conflict pre-emption. This doctrine can prevent state-law claims from proceeding where they conflict with federal law or its regulatory objectives.
In 2005, the U.S. Court of Appeals for the Fourth Circuit held that federal courts lacked subject-matter jurisdiction over four cases—Pinney, Farina, Gilliam and Gimpelson—and returned them to state courts. In the fifth case, Naquin, the court reversed the dismissal on pre-emption grounds and sent the case back for further proceedings.[1]
The subsequent procedural histories differed. Motorola’s 2006 Form 10-K reports that the plaintiffs dismissed Pinney without prejudice in April 2006 and Gilliam without prejudice in March 2006. The report also records that the Naquin plaintiffs dismissed their case without prejudice on 6 November 2006.[2] Motorola’s 2005 Annual Report records that the Gimpelson plaintiff dismissed that case without prejudice on 30 January 2006.[3] Farina continued separately, as discussed below.
These proceedings illustrate the distinction between a federal court’s authority to hear a case and the effect of federal law on particular state-law claims. The cases followed different procedural paths, and the appellate decision did not establish that mobile phone RF emissions cause or do not cause adverse health effects.
2. Farina v. Nokia Inc.
United States | 2001–2011 | Putative class action
Issue: Did manufacturers fail to provide adequate protection or warnings about RF exposure from mobile phones, in violation of state law?
Francis J. Farina filed a putative class action in 2001, alleging that mobile phones were unsafe to use next to the head without headsets because of RF exposure. His claims included alleged breaches of warranty and violations of Pennsylvania consumer-protection law.
The federal multidistrict litigation initially included this case. In 2005, the Fourth Circuit declined to rule on the merits of the pre-emption defence to Farina’s claims because it lacked jurisdiction. The court directed the parties to return the case to Pennsylvania state court. The court’s separate pre-emption ruling in that appeal concerned Naquin, not Farina.[1]
In a subsequent appeal, the U.S. Court of Appeals for the Third Circuit affirmed the dismissal of Farina’s amended complaint on 22 October 2010. The Third Circuit held that federal law pre-empted the claims because allowing a jury to find FCC-compliant phones unsafe on the basis alleged would conflict with the objectives of the federal regulatory framework.[4]
The U.S. Supreme Court declined to review the decision on 3 October 2011.[5]
The case illustrates how federal regulation can limit certain state-law product-safety and consumer-protection claims against mobile phone manufacturers. The decisions addressed jurisdiction and legal pre-emption; they did not constitute a comprehensive scientific determination of the health effects of RF exposure.
3. Cohen v. Apple Inc.
United States | 2022 | Product-safety and consumer-protection claims
Issue: Whether Apple could be held liable for allegedly misrepresenting or failing to disclose the RF emissions of its iPhones.
A group of iPhone users alleged that Apple misrepresented or failed to disclose the phones’ RF emissions, including allegations that the devices exceeded the applicable federal exposure limit. The plaintiffs brought claims under state tort and consumer-protection laws.
On 26 August 2022, the U.S. Court of Appeals for the Ninth Circuit upheld summary judgment for Apple, holding that federal law pre-empted the state-law claims. On appeal, the plaintiffs conceded that the iPhones complied with the FCC’s RF exposure limits but argued that the devices could still be unsafe despite that compliance. The court held that federal law pre-empted state-law claims seeking to impose liability based on RF emissions below the levels permitted by the FCC.[6]
4. Murray v. Motorola, Inc., and Related Proceedings
United States | Litigation beginning in 2001; appellate decisions in 2025 and 2026 | Consolidated personal-injury claims
Issue: Whether long-term mobile phone use caused brain tumours or brain cancer, as alleged by plaintiffs and the estates of people who had died from brain cancer.
The litigation began in 2001 and involved multiple appeals. The plaintiffs alleged that long-term exposure to mobile phone radiation had caused brain tumours, including gliomas and acoustic neuromas.
In earlier proceedings, the D.C. Court of Appeals held that federal law did not completely pre-empt the claims.[7] In a subsequent decision in 2016, the court adopted the Daubert standard for assessing the admissibility of expert testimony and remanded the litigation for further proceedings.[8]
On 17 July 2025, the D.C. Court of Appeals affirmed the exclusion of the plaintiffs’ expert testimony on general causation and the resulting summary judgment for Motorola and other telecommunications defendants. The appeal concerned 13 consolidated cases. The court also upheld the trial judges’ case-management and discovery decisions.[9]
The court concluded that the plaintiffs had not presented admissible expert evidence sufficient to establish general causation—that mobile phone radiation could cause the relevant types of brain tumours.
Brooks v. Mitsubishi Electric & Electronics USA, Inc. (2026)
In a related development, the D.C. Court of Appeals upheld summary judgment for the cellphone companies on 16 July 2026. The majority held that the Brooks plaintiffs had agreed to be bound by the Murray ruling on the admissibility of expert evidence concerning general causation and by the procedural rulings leading to that decision. Because the Murray plaintiffs’ expert testimony had been excluded and the Brooks plaintiffs lacked the required admissible expert evidence, the court upheld summary judgment against them. Senior Judge Thompson dissented, arguing that the Brooks plaintiffs had not agreed to be bound by the Murray case-management arrangements and should have been allowed to conduct their own discovery and present their own experts.[10]
Case status: On 27 August 2026, the D.C. Court of Appeals issued its mandate following its 16 July 2026 decision affirming summary judgment for the cellphone-company defendants. The official docket lists no pending post-decision matter or further scheduled action as of 28 October 2026.
5. Briganti v. Apple Distribution International Ltd.
Italy | 2026 | Consumer information and product safety | Remitted for reconsideration
Issue: Whether a mobile phone manufacturer adequately informed a consumer about potential health risks associated with prolonged RF exposure and measures that could reduce exposure.
The claimant alleged that she had not received adequate information about potential health risks associated with prolonged RF exposure from her iPhone SE or about measures that could reduce exposure.
On 24 July 2026, the Italian Supreme Court of Cassation issued Order No. 24015/2026, setting aside the Bologna Court of Appeal’s earlier judgment and remitting the case to that court for reconsideration by a differently constituted panel.[11]
The court held that compliance with technical standards or CE marking did not, by itself, exempt the manufacturer from its duties to provide adequate consumer information and take appropriate precautions. It explained that additional measures, including suitable warnings about risks not immediately apparent to consumers, may be necessary to protect consumer health.[11]
Case status: At the time of writing, the case had been remitted to the Bologna Court of Appeal for reconsideration. No subsequent final outcome could be confirmed from the publicly available sources reviewed.
Legal scope: The decision interprets Italian law within a framework that includes EU law. It does not automatically create legal obligations worldwide or determine the outcome of similar claims in other countries. Its reasoning may be relevant to comparable consumer-information disputes, depending on the applicable law and the facts of each case.
The ruling did not establish that Apple was liable, that the iPhone caused illness, or that RF exposure causes adverse health effects. It addressed the manufacturer’s legal duties and the need for adequate consumer information and appropriate precautions.
6. Canadian Class-Action Proceedings Against Apple and Samsung
Canada | Developments in 2022–2025 | Class-action proceedings
The Canadian proceedings concern allegations relating to RF exposure, consumer protection and the adequacy of safety information provided to cellphone users.
On 22 September 2022, the Quebec Superior Court authorised part of the proposed class action, including claims that inadequate safety instructions could breach Quebec’s Consumer Protection Act and support a claim for punitive damages. In September 2024, the Quebec Court of Appeal dismissed the manufacturers’ appeals, leaving the authorisation in place.[12]
In May 2025, the Supreme Court of Canada dismissed Apple’s and Samsung’s applications for leave to appeal the Quebec Court of Appeal’s judgment. The Court dismissed both applications with costs to the respondents.[13][14]
The Supreme Court’s refusal to grant leave was not a determination of the scientific merits of the RF-exposure allegations. It did not establish that either manufacturer was liable for harm or had breached consumer-protection requirements.
The Quebec class-action registry lists further case-management orders dated February and July 2025. However, the publicly listed documents reviewed for this article do not establish whether discovery has concluded or whether a trial date has been set. The current procedural stage beyond these recorded developments could not be confirmed from the publicly available registry.[12]
The proceedings allow the authorised claims to continue, but the allegations have not thereby been proven, and liability and damages have not been determined.
Regulatory Transparency and Access to Documents
Phonegate Alert and the European Commission: Access to iPhone 12 Documents
European Union | 2026 | Access-to-documents dispute
Phonegate Alert is challenging the European Commission’s decision on access to documents concerning the radiofrequency (RF) exposure compliance assessment of the iPhone 12 A2403.
In a confirmatory decision dated 10 August 2026 (C(2026) 5810), the Commission granted full access to some documents, partial access to others and refused access to certain information. The decision concerns documents relating to technical aspects of the iPhone 12 assessment, including testing procedures, technical configurations and the Time Averaged SAR (TAS) procedure.[15,17]
Phonegate Alert argues that further disclosure is needed to enable independent scrutiny of the testing and market-surveillance process. The association challenges the withholding of information on commercial-confidentiality grounds and argues that environmental-information law and the public interest in transparency support greater disclosure. These are the association’s legal arguments; they have not yet been determined by the Court.[15,17]
On 19 October 2026, Phonegate Alert brought an action for annulment before the General Court of the European Union, challenging the Commission’s decision. Registered as Case T-697/26, Alerte Phonegate v Commission, the case is pending.[16]
The dispute concerns access to regulatory documents and the balance between commercial confidentiality and public transparency. It is not a direct personal-injury claim against Apple. The filing does not establish that the Commission acted unlawfully, that testing was deliberately manipulated or that the iPhone 12 caused harm.
Occupational Health: Claims Involving Mobile-Phone Use at Work
Italian courts have considered several individual occupational compensation claims brought by workers who attributed tumours affecting nerves in the head to prolonged use of mobile or cordless phones at work. These proceedings concerned entitlement to compensation from INAIL, Italy’s workers’ compensation authority.
The courts assessed the evidence in each individual case, including the reported exposure history and medical expert opinions. The outcomes must be understood in the context of the facts and legal standards applicable to each claim; they do not, by themselves, establish that mobile-phone use generally causes tumours.[18]
Marcolini v. INAIL (Italy, 2012)
In judgment No. 17438 of 12 October 2012, the Italian Court of Cassation rejected INAIL’s appeal, leaving in place an award of occupational disability compensation to a worker who had used mobile and cordless phones at his left ear for approximately five to six hours daily over 12 years.[18]
The diagnosed tumour was a neurinoma of the Gasserian ganglion, affecting the trigeminal nerve. This is distinct from an acoustic neuroma, which affects the vestibulocochlear nerve. The Brescia Court of Appeal had awarded an occupational disability pension based on an assessment of 80% disability.
The lower court had found the evidence sufficient to support a probable causal link between the worker’s prolonged occupational exposure and his illness under the legal standard for recognising an occupational disease. The Court of Cassation found no legal error warranting reversal of that decision.[18]
Outcome: The occupational compensation award was upheld. The decision recognised a causal contribution in this individual case under the applicable occupational compensation standard; it did not establish that mobile-phone use generally causes tumours.
Romeo v. INAIL (Ivrea, 2017; Turin Court of Appeal, 2020)
In Romeo v. INAIL, the Ivrea Labour Court, in judgment No. 96/2017, recognised Roberto Romeo’s claim for occupational compensation relating to an acoustic neuroma. The court found that the condition had caused permanent biological impairment assessed at 23% and ordered INAIL to pay the corresponding benefit.[19]
INAIL appealed. On 13 January 2020, the Turin Court of Appeal, in judgment No. 904/2020, rejected the appeal and upheld the award. After reviewing additional medical expert evidence, the court concluded that the evidence supported a causal link between Romeo’s prolonged occupational use of mobile phones and his illness, applying the civil-law standard of “more likely than not”. [20]
Outcome: The occupational compensation award was upheld on appeal in 2020. No subsequent decision by the Italian Court of Cassation could be confirmed from the publicly available sources reviewed.
A.M. v. INAIL (Florence, 2017)
In Judgment No. 391/2017, the Florence Labour Court considered a claim by a worker whose employment involved prolonged mobile-phone use. The worker had developed a neurinoma of the eighth cranial nerve, also known as an acoustic neuroma, affecting the right side.
The judgment records occupational mobile-phone use from 1994 to 2007, including approximately three hours daily until 1997 and at least two hours daily from 1997 to 2007. After considering medical expert evidence, the court accepted that occupational exposure could have contributed to the development of the illness.[21]
The court ordered INAIL to pay an occupational disability benefit based on a permanent impairment assessment of 16%, effective from 12 February 2013.[21]
Outcome: The court awarded an occupational disability benefit based on a 16% permanent impairment assessment. No subsequent appeal or Court of Cassation outcome could be confirmed from the publicly available sources reviewed.
Aosta Labour Court and Turin Court of Appeal (2020–2022)
This occupational compensation case concerned a worker employed at a steelworks in Aosta who developed a neurinoma of the left acoustic nerve, commonly called an acoustic neuroma. He attributed the illness to extensive mobile-phone use during his employment between 1995 and 2008.
In judgment No. 25/2020, published on 4 July 2020, the Aosta Labour Court partially upheld the claim and ordered INAIL to pay the benefit corresponding to a permanent impairment assessment of 53%.[22]
INAIL appealed. On 3 November 2022, the Turin Court of Appeal, in judgment No. 519/2022, rejected the appeal and upheld the award. The appellate court obtained a further medical expert assessment to examine the causal relationship between the worker’s occupational exposure and his illness.[22]
The judgment records evidence of extensive phone use during working hours and additional use outside working hours while the worker was on call. The expert assessment considered different estimates of cumulative exposure, reflecting assumptions about the exposure period and daily use. The appellate expert assessed overall biological impairment at 57%, but the court could not increase the award because the worker had not appealed the original impairment assessment.
Outcome: The original compensation award, based on a 53% impairment assessment, remained in place after the appeal. The appellate court accepted a causal link in this individual occupational compensation case; its decision did not establish a general causal relationship between mobile-phone use and acoustic neuromas.
No subsequent Court of Cassation outcome could be confirmed from the publicly available sources reviewed.
What do the Italian compensation rulings establish?
Italian court decisions awarding compensation for tumours that claimants attributed to prolonged occupational use of mobile phones are relevant to the debate about radiofrequency (RF) exposure and health. In several cases, courts accepted evidence of a causal or contributory relationship between the claimant’s exposure and the diagnosed condition under the applicable Italian legal test. These findings should not be dismissed or misrepresented.[18–22]
However, a finding in an individual case is not equivalent to establishing a general causal relationship across the population. The courts assessed the evidence presented in particular proceedings, including expert medical opinions, the claimant’s exposure history and the applicable legal standard. The outcomes do not, by themselves, establish the magnitude of any risk to ordinary mobile-phone users or resolve the wider scientific debate.
The distinction works both ways: a court ruling does not, on its own, establish a general scientific conclusion, but neither does uncertainty in the wider scientific evidence invalidate a court’s findings in an individual case. The Italian decisions therefore form part of the legal record and warrant consideration alongside epidemiological research, scientific reviews and assessments by public-health authorities.
Overall Assessment
Mobile Phone Radiation Litigation encompasses several distinct types of legal proceedings. Some cases have been dismissed because of federal pre-emption or because plaintiffs did not present expert evidence that met the applicable admissibility standards. Others have concerned consumer-information duties, the procedural requirements for class actions, individual occupational compensation or access to regulatory documents.
The outcomes must be understood within their respective legal contexts. A decision allowing a claim to proceed is not proof that the allegations are true. A refusal of leave to appeal does not necessarily determine the scientific merits. An occupational compensation award concerns the evidence and legal criteria applied to an individual claimant, while an access-to-documents dispute concerns transparency and the law governing disclosure.
Taken together, these cases illustrate how courts address questions of evidence, regulatory authority, consumer information and access to documents. They do not amount to a single, uniform judicial conclusion about the health effects of mobile-phone radiofrequency (RF) exposure.
