The so-called permitted reliability means the people have the right to assume and rely on the well kept abided normal responsibility of other social life attendants. Based on the reliability, the behaviour of people can avoid legal reliability. Moreover, on the basis of risk distribution, under the principle of reliance, it is naturally that the level of tolerable risk rises. If the permitted reliability cannot be a reason to escape legal reliability, the meaning and function of social life rule will be denied, and the life of human beings will become a burden which surpasses the limitation of human beings ability. Recently year, the development of specialization of doctors' jobs, the reduced cure burden under the implemented the national health insurance, and the increase of patients' independent consciousness have been led to that the patients are used to asking more opinions or cures from other doctors. It is questionable whether the doctors can depend on the inspection report from previous doctors in order to avoid other repeated examines. Also, the question whether the doctors can evade legal responsibility under the principle of reliance, if there are medical disputes, is discussed in the report. Following one verdict from the Taiwan Banciao District court, we introduce and analyze these questions. Via case study, the report sheds light on how to apply permitted reliability in cure behaviour.
