A divided Michigan Supreme Court ruled in a 4-to-3 decision that the state’s attorney general may proceed with an investigation into Eli Lilly over its insulin pricing practices. The ruling overturns a lower court decision, reviving a probe launched four years ago by Attorney General Dana Nessel under state consumer protection laws.
In Plain English: The Clinical Takeaway
Reviving the State Probe Into Pricing Strategies
The Michigan Supreme Court’s 4-to-3 ruling removes legal barriers that had previously stalled an investigation initiated four years ago by Michigan Attorney General Dana Nessel. According to state court documents, the probe centers on allegations that Eli Lilly artificially inflated the costs of three widely prescribed insulin products: Lispro, Humalog, and Basaglar.
State filings argued that these pricing practices forced vulnerable patients to ration their doses, restrict necessary dietary intake, or seek less-effective alternative treatments.
