This paper intends to explore the influences of feminist legal activism in Taiwan and therefore to theorize feminist action from the perspective of legal pluralism. The three influences are as follows: challenging law as patriarchal, changing law’s practice through new institution, and revealing power relationship by legal consciousness raising. Although these three aspects all face their own difficulties to deepen the influences, the author lastly propose an optimistic legal feminism that does not focus on law's social effect or law's power to social change but on the reflexibility and possibility of prompt responses of legal feminism for social problems.
