Siopes v. Kaiser Found. Health Plan, Inc.Annotate this Case
Respondents in this case included Kaiser Foundation Health and Kaiser Foundation Hospitals (collectively, Kaiser). Michael Siopes, a public school teacher, enrolled in a Kaiser health plan offered through the Hawaii Employer-Union Health Benefits Trust Fund (EUTF). Michael was later diagnosed with cancer by a Kaiser medical professional. Michael and his wife, Lacey, subsequently consulted a medical team at Duke University Medical Center. The Duke team determined that Kaiser's diagnosis was erroneous and recommended a different treatment plan. Michael received treatment at Duke that was ultimately successful. Kaiser denied Michael's request for coverage. Michael and Lacey sued Kaiser for, among other things, breach of contract and medical malpractice. Kaiser filed a motion to compel arbitration, arguing that a group agreement entered into Kaiser and the EUTF was applicable to Michael when he signed the enrollment form. The group agreement contained an arbitration provision. The circuit court granted the motion to compel arbitration. The Supreme Court vacated the circuit court's orders, holding (1) the arbitration provision was unenforceable based on the lack of an underlying agreement between Kaiser and Michael to arbitrate; and (2) accordingly, Lacey was also not bound to arbitrate her claims in this case.
