Pablo Fajardo Mendoza is an Ecuadorian lawyer and activist. He led the litigation against Chevron Corporation related to the environmental disaster he alleged was caused by the oil operations of Texaco in the Lago Agrio oil field between 1964 and 1990. In this process, Fajardo represented the over 30,000 local inhabitants affected by the spill of crude oil and toxic waste. Chevron, which instead blames Petroecuador and has not paid the judgement, has had repeated success in arguing against it. The judgement has been validated by further Ecuadorian courts and the Supreme Court of Canada but it has been declared fraudulently obtained by the United States District Court for the Southern District of New York and an arbitration court in The Hague.
