Every year, Oppenhoff welcomes six Willem C. Vis Moot Court teams from various German universities to its Cologne office. Due to Corona, this year's Cologne Vis Moot School, which serves as preparation for the "serious case" in Vienna, will once again take place online. Together with their coaches, the mooties will be specifically prepared for the competition in international business law. Before the pleadings, there is comprehensive voice coaching and argumentation training with external coaches. Afterwards, the mooties can hold their pleadings in front of our lawyers, who act as referees.
