The Grand Justices have reiterated that the right of property shall be guaranteed to the people. However, this has not been able to set things into the right way when government agencies are performing their duties. Why is this happening? One of the reasons why there are so many excessive land expropriation in Taiwan should be that the redemption right, which is the last but not least phase of the land expropriation compensation, has not been exercised properly. The original intent of the redemption right is to prevent any excessive land expropriation by any government agencies in the name of public interest. Nevertheless, over the years, the language of the statute, the administrative practice, court decisions, the resolutions of the judge-council and the interpretations of Grand Justice Counsel have been very strict on the application of the redemption right. This leads to the possibility of excessive land expropriation due to an extremely narrow interpretation of redemption right by the statute, the administrative orders, the decisions and resolutions of Supreme Administrative Court and the interpretations of Grand Justices Counsel. In light of the difficulties of interpreting the redemption right of land expropriation, this article aims to provide other possible interpretations.
