[Recent developments in medical law].

The most spectacular aspect is the extremely rapid expansion of medical law. Even if there is a close connection between developments in medicine and in law, the question must be asked as to what extent new discoveries and advances in medicine play a dominant role here, and to what extent the emphasis is on the further development of law. How advances in medicine can give rise to new legal problems was most impressively demonstrated some time ago by the discussion about cerebral death. In view of the progress made in the field of re-animation and intensive care, the current question is whether or not the physician's duties and rights to maintain life should be limited in hopeless cases when patients are incapable of making decisions themselves. This is demonstrated in particular by the discussion about the binding character of "patient testaments" in which healthy subjects declare that they do not want treatment under such circumstances. The decisive factor will continue to be the presumptive will of the patient at the respective time, and this will have to be ascertained considering all circumstances prevailing at that time. New questions with regard to the ethical and legal limitation of the technically feasible also arise from the possibility of culturing embryos from legal abortions or extracorporally fertilized ova to obtain transplants, and from the possibility of implanting extracorporally fertilized ova into the uterus, perhaps that of a "hired childbearing wet-nurse." In addition to ethical and legal problems, questions of parentage would arise here similar to those already of current interest in connection with artificial heterologous insemination. For physicians practicing these methods, questions concerning liability and the limitation of professional secrecy vis-à-vis the semen donor might become the issue of law suits in the near future. Current problems of "unsuccessful sterilization" and nonperformance of an abortion through the physician's fault although abortion was indicated for eugenic reasons are, on the other hand, primarily due to the fact that the law--possibility even for acceptable reasons--establishes legal obligations for the physician which, in the last analysis, aim at preventing human life from coming into being.(ABSTRACT TRUNCATED AT 400 WORDS)
