The first notable case regarding the right to water in the ICSID is that of "Azurix Corp v. Argentina". The dispute was between the Argentine Republic and Azurix Corporation regarding discrepancies arising from a 30-year contract between the parties to operate the water supply of various provinces. A consideration in regard to the right to water is implicitly made during the arbitration for compensation, where it was held that Azurix was entitled to a fair return on the market value of the investment. This was rather than the requested US$438.6 million, citing that a reasonable business person could not expect such a return, given the limits of water price increases and improvements that would be required to ensure a well-functioning, clean water system.
