The article challenges some normative and evaluative prerequisites and consequences of distinct approaches put forward in the current German debate on (physician-) assisted suicide. First, two alternative types of understanding and using the concept of self-determination (Selbstbestimmung) within this debate are identified, concluding with the result of rejecting one while justifying the other. Second, it is argued in favour of a state preferring a rule of law which secures and supports a relationship-oriented and inclusion-sensitive lifestyle of as many citizens as possible. Against this background, the consequence is drawn to sustain the general prohibition of physician- assisted suicide within the established Professional Code for Physicians in Germany.
