A woman had an IUCD inserted and her GP believed it had fallen out. The woman later wished to become pregnant and had difficulties conceiving. It was subsequently discovered the IUCD had perforated the wall of the uterus and translocated into the peritoneal cavity. The IUCD was removed and the woman conceived shortly afterwards. The medical evidence was that the IUCD would have been continuing to prevent conception. The woman claimed for ACC cover for her prolonged infertility. ACC accepted cover for the perforation of the uterine wall but declined cover for the infertility, finding that infertility was not a physical injury. The District Court disagreed, finding two possible grounds for cover for the prolonged infertility. The first ground was that the infertility itself was a physical injury as it was caused by a physical mechanism, namely a "physically altered state of [the woman's] biological process". The second ground was the chain of causation between the covered personal injury (the perforation of the uterine wall) and the prolonged infertility. The Court granted the woman cover for her prolonged infertility. SR v Accident Compensation Corporation [2011] NZACC 355.
