The article analyzes the results of the legislation on accelerated nuclear phase-out in Germany developed by German government. The decision was taken in short time and without discussing with business reps what led to significant infringement of rights of the nuclear industry which decided to seek judicial protection. As a consequence the German government ended up as a defendant in Federal administrative court, Federal constitution court and as a respondent in ICSID. The results of those litigations were mostly unfavorable for German government what once again proves the necessity of making more thorough legal and business impact analysis while passing a legislation.
