Example

Using Jus Mundi, what do ICSID tribunals say about umbrella clauses in investment treaties since 2010?

I ran the question under your signed-in account, scoped to ICSID awards from 2010 onward. Two awards support treating an umbrella clause as a basis for contract claims, and one tribunal declined to follow that reading. The sources are labelled stated or inferred, and the research does not establish the rule across all tribunals.
