This volume contains the papers and proceedings of the 10th Anniversary Juris Conference. Our group of 10 authors again take contrary positions and grapple with the dramatic developments of investment arbitration over the past 10 years. With TPP and TTIP on the horizon, half of our authors take the view that the field is a doomed experiment and the other half of our authors paint a picture of a revolutionary development in a still nascent form, with more greatness yet to come. The debate continues!
