Chapter 4 deals with a complex set of problems that have arisen in determining the relationship between parallel claims in investment arbitration and other forms of dispute resolution, including proceedings in host State courts. Five issues which arbitral tribunals have had to confront in considering the impact of other forms of dispute resolution upon their jurisdiction are explored in particular: (1) the distinction between breach of contract and breach of treaty; (2) election, waiver, and ‘fork in the road’; (3) prior resort to local remedies; (4) internationalised contract claims and ‘umbrella clauses’; and (5) parallel treaty arbitration. The chapter considers the extent to which the general doctrines of lis pendens, res judicata, election, waiver, and abuse of process are capable of application in investment treaty arbitration.
