Dr Simpson


An arbitrator's subject-matter expertise is important, and arbitrators add value and efficiency when their work is interdisciplinary.

Disputes rarely occur in a silo, and disputes rarely adhere to the nicities of subject-matter boundaries.  A dispute involving energy production, for example, will undoubtedly involve a range of subject areas, whether in environmental law, public-private partnerships and procurement regulations, antitrust, subsidies, commercial contracts, health and safety, criminal, or even employment law.  Likewise, an employment dispute may involve issues related to reasonable accommodations, commercial contracts, fraud, tax, or wage and hour concerns.  All of these disputes will involve further procedural, due process, and/or evidentiary complexities.

Regardless of who is appointed, that arbitrator will need to be able to identify, address, and manage each of these complex issues.

Even where disputes do not involve the immediate subject matter of other disciplines, they can benefit from the dispute resolution tools that have been developed elsewhere.  Just as international commercial and investment disputes have their foundations in the procedures that were developed for US labor disputes, domestic mass claims arbitrations can benefit from the document exchange processes that were developed to facilitate international matters.


Prof. Dr. Karl-Heinz Boeckstiegel (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 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."
