The 12 activists had been sentenced to just eight months in jail for flying Morning Star separatist flags in Manokwari regency, West Papua, several times in March last year. They appealed that the Manokwari District Court decision.

Yan Christian Warinussy, the defendants' lawyer, said Friday the high court had overreacted with its decision.

"The court said in its verdict the defendants had engaged in a rebellion and were trying to set up a separate country. What actually happened in Papua contradicts their view," he said.

The activists hoisted the flags during rallies protesting government regulation 77/2007 which bans the display of separatist flags. (dre)
