In July 2018, the Legislative Yuan passed the high-profile amendment to the Taiwan Company Law ("the Company Law"). Director's right to information is one of the most, if not the most, controversial proposed amendment. The proposed Article 193-1 drafted by the Executive Yuan has included the right herein, nonetheless, the Article was turned down by lawmakers across the aisle, thereby becoming one of the few draft proposals which are not put into law at the end. This paper suggests that, in the wake of the failed proposal, another attempt to stipulate director's right to information in the Company Law is much needed under current circumstances. This paper first examines the related provisions on the right to information in the Company Law, especially the Article 218 regarding supervisor's right to information, which offers the supervisor unrestricted access to information. In light of historic and systematic interpretation of the Company Law, this paper strongly argues that lawmakers have never intended to confer the same right to information to directors as to supervisors since the overhaul of the Company Law in 1966. Based on the finding, this paper further looks into the development of the legal regime of director and that of supervisor, and offers a critical analysis on the supervisor's unrestricted right to information. To conclude, this paper offers legislative suggestions on director's and supervisor's right to information.
