He added that the Chilean government is to file its rejoinder to Peru’s reply by July 11. After that, the international court will set a date for the oral stage or the public hearing.
"What we know is that Chile must file its rejoinder to our reply on July 11 and that after that, at some point, the Court is going to set the date for the oral stage, that is, the public hearing for the Peruvians. Then, the Court takes its time to review the case and prepare his sentence."
He estimated that the sentence could be ready by 2012 or perhaps in 2013.
Peru took Chile to the International Court of Justice (ICJ) in the Hague to establish a maritime borderline as it claims that there is not any formal agreement for maritime delimitation between the two neighbouring nations.
Chile, in turn, believes that the maritime borderline has already been demarcated in agreements of 1952 and 1954.
