Dignitas (Swiss non-profit organisation)

Dignitas is a Swiss non-profit members' society providing assisted/accompanied suicide to those members of the organisation who suffer from terminal illness and/or severe physical and/or mental illnesses, supported by (of the organization independent) qualified Swiss doctors. They have helped over 2,100 people die at home within Switzerland and at Dignitas' house/flat near Zürich. Additionally, they do advisory work on palliative care, health care advance directive and suicide attempt prevention and they have been leading and supporting numerous court cases and legislation projects for right-to-die laws around the world. Members of Dignitas who wish for an assisted suicide have to be of sound judgement, themselves able to do the last act which brings about death, and submit a formal request including a letter explaining their wish to die and most of all medical reports showing diagnosis and treatments tried. For people with severe psychiatric illnesses, additionally, an in-depth medical report prepared by a psychiatrist that establishes the patient's condition, is required as to a Swiss Supreme Court decision.

Dignitas was founded 17 May 1998 by Ludwig Minelli, a Swiss lawyer specialising in human rights law. Swiss laws provide that assistance to suicide is legal as long as it is not motivated by selfish motives. The person who wishes to die meets several Dignitas personnel, in addition to an independent medical doctor, for a private consultation. The independent doctor assesses the evidence provided by the patient in advance and is met on two separate occasions, with a time gap between each of the consultations. Legally admissible proof that the person wishes to die is also created, in the form of a signed affidavit, countersigned by independent witnesses. In cases where a person is physically unable to sign a document, a short video film of the person is made in which they are asked to confirm their identity, that they wish to die, and that their decision is made of their own free will, without any form of persuasion / coercion. This evidence of informed consent remains private and is preserved only for use in any possible legal dispute.

Finally, a few minutes before the lethal overdose is provided, the person is once again reminded that taking the overdose will surely kill them. Additionally, they are asked several times whether they want to proceed, or take some time to consider the matter further. This gives the person the opportunity to stop the process at any time. However, if at this point the person states that they are determined to proceed, a lethal overdose is provided and ingested.
