There is the limit of the traditional legal hermeneutics and fragmentary or individual theoretical legal approach to suggest the desirable solution of Korean health care law system to have many issues. Law & politics research is the legal research method to suggest the resonable understanding and seeking the measures through various approach, decide and evaluate that the legal methods can be functioned as the optimum system design. Law & politics research has some procedure. 1. It is demanded to catalog the comparison target of legal system by its topic. 2. It is demanded to compare it with Korean situation. 3. The realistic and empirical legal research to the compared policy alternatives is needed. 4. Reflecting the results of this research work, the desirable policy idea must be adopted. 5. The accomplishment of this policy idea must be come true as a specific legislation through interest coordination. 6. This plan must be come into force and the feedback to effect of society must be examined closely. Here I will review generally the contribution of law & politics research to health care law system because of the problem of time and the insufficiency of law & politics research. The constitutional consideration is important to support the interest coordination because of the shortage of resources. The comparative law research can compare our health care system with those of other countries and seek some desirable alternatives. If we discuss the law system plan in a long time and synthetically from different perspectives, more desirable helath care law system can be deducted.
