A Polish man jailed for treason in West Papua is to appeal his conviction and sentence in Indonesia's Supreme Court.
Jakub Skrzypski was in May jailed for five years after a judge in the Wamena District court ruled he had plotted to sell arms to the West Papua Liberation Army.
An appeal filed against the sentence by Skrzypski's lawyer in the High Court in Papua was last month rejected.
State prosecutors had also twice appealed, looking for a doubling of the length of his five year sentence, but the court upheld the sentence as well as continued confiscation of Skrzypski's property seized when he was arrested in August last year.
Furthermore, prosecutors unsuccessfully sought an increase in the four-year sentence of a West Papuan co-defendant, Simon Magal.
Skrzypski, a tourist who had travelled extensively in Indonesia, will now appeal the sentence in the Supreme Court.
Prosecutors are also going to the country's highest court with their own appeal.
