A farmer left $10.9 million to build a cancer centre; Mayo Clinic was supposed to get it only if the local hospital lost its independence | World News

Iowa farmer Herman Carl Stille died in September 2020 at 94, leaving an estate worth about $10.9 million. His 2017 will directed the remainder to Floyd County Medical Center (FCMC) in Charles City to establish a cancer centre for local residents. It also named the Mayo Foundation as the alternative recipient, for Alzheimer’s research, if the hospital lost its independence and became part of a major healthcare corporation. Mayo went to court after the hospital found it could not provide radiation treatment. On May 1, 2026, the Iowa Supreme Court ruled in favour of the medical centre.

A farmer’s $10.9 million will with two conditions

Stille was a cattle farmer and factory worker before he retired. He never married, had no children and left no living siblings or other identified heirs. He received care at FCMC for more than a decade and was the largest donor to the hospital’s charitable foundation.He was also a Mayo patient in Rochester, Minnesota, and had given to its charitable foundation. His last gift there came in January 2017. He stopped donating because he was dissatisfied with the care he received, and his later gifts went to FCMC alone.The $10.9 million estate was mostly farmland. After several small charitable bequests, his will, signed in August 2017, gave the remainder to the hospital for a cancer centre. It required an oncologist on staff, office and consultation space, a family area and separate areas for radiation, chemotherapy and other treatments. The gift was contingent on the hospital staying independent. If it lost its independent status and joined a major healthcare corporation, the remainder would go to Mayo Foundation for Alzheimer’s research.Attorney Michael Kennedy, who drafted the will, testified that Stille added the independence requirement in 2017. Stille’s earlier will, from 2011, had no such condition and named Mayo as the backup only if the cancer centre could not be established. Stille’s sister had died from Alzheimer’s complications, and he feared facing the same disease.

Radiation proved impossible

After Stille’s death, FCMC began planning the centre, expecting roughly $10 million from the estate. Administrators soon realised they could not provide on-site radiation. Radiation requires a linear accelerator, which is costly and heavily regulated. In Iowa, a hospital needs a certificate of need, and one is generally not issued when radiation facilities already operate within a certain radius. Several hospitals near FCMC already offered radiation. The machine is also expensive to run, and FCMC lacked the patient base to afford its upkeep.The hospital said the centre could still satisfy the other requirements. It proposed to staff an oncologist through cooperation or subcontracting with other facilities, and to transport patients to another facility for radiation. It also noted that more cancer patients are treated with chemotherapy than with radiation.

Mayo’s challenge

Mayo asked the court to rule that the gift to FCMC had failed. It argued that the will’s conditions went beyond independence, and that the money should pass to it if FCMC could not build the centre Stille described. Kennedy testified that Stille’s intent was for the money to go to Mayo if either condition was unmet.FCMC countered that it had remained independent, so the trigger for Mayo’s gift had never occurred.The Chickasaw County district court, after a three-day bench trial, ruled for FCMC in June 2025. It found that the hospital was independent and that its planned centre would meet five of the six specifications, all but radiation. The judge concluded that Stille cared more about the hospital’s independence than about how the centre would operate, and would not have withdrawn the bequest had he known radiation was impossible.

Iowa Supreme Court affirms on standing

Mayo appealed, and the Supreme Court retained the case. On May 1, 2026, it unanimously affirmed, in an opinion by Justice Thomas Waterman. Justice Mansfield took no part.The court did not adopt the district court’s reasoning. It found no ambiguity in the will, which conditioned the gift to Mayo on FCMC’s loss of independence. Because FCMC remained independent, and Mayo did not dispute that, the court held that Mayo takes nothing under the will. A beneficiary whose condition has not occurred lacks standing to challenge the gift to someone else, so the court affirmed on that basis alone and did not reach the remaining issues.The court noted that FCMC still has a legal and moral obligation to use the funds as intended. Mayo cannot enforce it, but the Iowa attorney general has standing to enforce the terms of charitable trusts.The ruling ends a dispute that began in 2021 and leaves the remainder of the $10.9 million estate with FCMC. The hospital says it will proceed with the Stille Cancer Centre on its campus. It says it is still unclear which cancer services will be available, including how radiation care will be provided for patients who need it.
