Medical staff at University Hospital Galway denied her request for an abortion following an incomplete miscarriage on the grounds that granting her request would be illegal under Irish law, ultimately resulting in her death from septic miscarriage.
Her death served as a rallying cry for efforts to repeal the Eighth Amendment of the Constitution of Ireland, which prohibited abortion in most instances.In the wake of her death, the passing of the Thirty-sixth Amendment of the Constitution, which repealed the Eighth Amendment, empowered the Oireachtas to legislate for abortion.
It did so through the Health (Regulation of Termination of Pregnancy) Act 2018, signed into law on 20 December 2018.
