TORONTO (AP) — An attempt by Ecuadorian villagers to have a Canadian court enforce a $19 billion judgment awarded in their country against multinational oil giant Chevron Corp. faced a judge’s skepticism Thursday.

Ontario Superior Court Justice David Brown heard arguments on Chevron’s motions to challenge jurisdiction but wondered whether he could issue a ruling since an appeal is pending in Ecuador’s constitutional court. He also said the case should be heard in the U.S., not Canada.
