Two Panamanian prosecutors have deemed the contract unconstitutional after examining legal challenges submitted to the court.
First Quantum did not reply to a request for comment on the future of the contract pending court proceedings.
Panama's mining chamber has urged against canceling the contract, saying First Quantum could sue Panama for at least $50 billion.
Another lawyer said the court could also move to declare parts of the contract unconstitutional, which would not annul it completely.
