About the book

In 1996, Judge Rosalyn Higgins noted that ‘fair and equitable treatment’ was a legal term of art well known in the field of overseas investment protection. In 2015, fair and equitable treatment has emerged as a rule of considerable practical importance in dispute settlement on the basis of investment treaties. According to the most recent review of investment arbitrations conducted by UNCTAD, ‘[o]f the seven decisions finding States liable [that were rendered in 2013], five found a violation of the fair and equitable treatment (FET) provision and two of the expropriation provision’ (UNCTAD, Recent Developments in Investor-State Dispute Settlement (ISDS), IIA Issues Note no 1/2014, 10).

Similarly, in 2012, ‘[o]f the twelve decisions finding State’s liability, six found a violation of the FET provision, five of the expropriation provision, two of the umbrella clause and one of the prohibition of certain performance requirements’, (UNCTAD), ‘Recent Developments in Investor-State Dispute Settlement (ISDS)’ (IIA Issues Note no 1/2013) 5).

Debates about the best approach to interpretation and application of fair and equitable treatment therefore touch upon the most important aspects of contemporary international investment law. The launch of the paperback edition of Martins Paparinskis new book, The International Minimum Standard and Fair and Equitable Treatment (OUP, 2014) provides an opportunity for a reflection upon these issues.
