Can a guy with dual citizenship (Philippine/USA) committed forgery by fabricating an SPA be extradited?

Extradited from USA where he now lives - to the Philippines where the crime was committed if he is served a subpoena. His partner in crime, (co-signer of bogus Special Power of Attorney) still lives in the Philippines. Can both of them be equally prosecuted where crime occurred? They keep selling land that is not theirs using bogus SPA.
