Prof. Dr. Karl-Heinz Böckstiegel (2018): Starting from her time some eight years ago when she was at Cologne University, Katherine Simpson has helped me in many of the commercial and investment cases I chaired, as Secretary or Assistant to the Tribunal. She proved to be highly efficient in supporting my case management, researching sources, or providing narrative drafts for decisions the Tribunal had to make. Other members of the tribunal and the staff of various arbitration institutions appreciated her work and she was well respected by counsel of the parties. Obviously, over the years, she gained a large amount of experience and I have no doubt that, by now, she could efficiently and successfully serve as an arbitrator.
Prof. William W. (Rusty) Park (2018): Dr. Simpson has been an excellent Tribunal Secretary and has now doubtlessly arrived at the point where she will provide fine service as an efficient and intelligent arbitrator.
