Study Description(click to expand)

Switzerland is the only country in the world that enables assisted suicide by lay people, i.e., people who are not physicians. All other countries that have adopted aid-in-dying legislation require that a physician provides this assistance. This project probes the reasons for adopting this policy, and the advantages and the disadvantages of the Swiss model at the end of life. Are the Swiss aid-in-dying volunteers able to provide well-informed assistance to patients in need? Is the Swiss model one to be followed by other nations? The project will focus on the work of the Swiss aid-in-dying societies. The study draws on research in the fields of ethics, law and medicine. Its novelty lies in incorporating different methods of analysis, reflecting on the right to die with dignity within a liberal framework that aims to respect fundamental human rights.
