Key points

  • ▪The Supreme Court examined a phone identification mechanism that exposed sensitive medical data using only an ID number.
  • ▪Clalit Health Services changed its identification mechanism following the legal hearing to link recognized phone numbers with the HMO's systems.
  • ▪The Supreme Court ruled that the request was not a frivolous lawsuit and provided real benefits to members.
  • ▪The proceedings ended with the dismissal of the certification request after the HMO resolved the technological issue.
  • ▪Clalit was ordered to pay compensation and legal fees to the appellant and her counsel, canceling a previous cost order from the District Court.

The Supreme Court recently addressed the issue of member privacy at Clalit Health Services, as part of an appeal against the dismissal of a class action certification request filed by Nona Day. At the heart of the proceedings was the identification mechanism in the HMO's telephone service center, which allowed for the retrieval of personal and medical information, including future appointments, physician identities, and clinic locations, solely by entering an ID number.

During the hearings, Justice Ofer Grosskopf illustrated the importance of the issue with a hypothetical example of a public figure, demonstrating how the disclosure of medical details could infringe upon patient privacy. The appellant argued that the disclosure of such information could reveal medical behavioral patterns and daily routines. In contrast, the HMO argued that the information provided was technical in nature and that the call center is essential for populations that do not use advanced technological means.

Following comments from the Supreme Court during the hearing, Clalit acted to change the technological mechanism. Under the new policy, automated services are provided only to members calling from a mobile phone number updated in the HMO's systems and linked to their ID number. If there is no match between the phone and the ID, the information is not provided. Furthermore, procedures on the website and in the patient guide were updated. Following these changes, the appellant no longer insisted on continuing the certification request.

However, the dispute regarding the compensation and legal fees remained for the court's decision. In the verdict, delivered by Justices Yael Willner, Ofer Grosskopf, and Ruth Ronen, it was determined that the request raised a substantial and important issue in the field of privacy protection and that this process indeed yielded benefits for the group members, totaling approximately 5. 5 million people. The Court overturned the District Court's decision, which had dismissed the request and ordered the appellant to pay legal costs, and instead dismissed the certification request.

Clalit was ordered to pay compensation to the appellant and legal fees to her representatives, as well as to reimburse the paid court fees. The Court clarified that the dismissal does not prevent individuals who believe they suffered damage from the previous mechanism from filing individual lawsuits on the matter.
