The sixth hearing of the trial of Forkorus Yaboisembet and his four colleagues took place on 21 February at which seven witnesses for the prosecution were called to give evidence. According to the executive-director of the LB3PH, Yan Christian Warinussy, six of the seven of the witnesses were members of the police force who  had been involved in the attack against the Third Papuan Peace Conference (KRP-III) on the third day of the event, 19 October 2011.Six of these witnesses were unable to answer questions from the chief prosecutor regarding the declaration that was allegedly read out at the end of the  conference nor could they say whether the five defendants had been involved in a criminal conspiracy to set up the Federal Republic of West Papua.One of the witnesses who had been summoned was Drs Alfons Rumbekwan, a member of the Majelis Rakyat Papua. Speaking for the defence team, Olga Helena  Hamadi said that this person should not testify at the trial because the majelis of which he is a member is the cultural body of the indigenous Papuan people. Since the trial was related to the political aspirations of the Papuan people, his appearance might cause a conflict between the MRP and the Papuan people. It was agreed that Drs Rumbekwan  would not be called to give testimony.

According to a lengthy report of the hearing in Bintang Papua, the police witnesses appeared not to know the defendants and were unaware of the declaration by Forkorus calling for the re-establishment of the Federal Republic of West Papua.

According to Bintang Papua, for example, the first witness, Lambertus Limbong Sattu, a member of the Jayapura City police force who reportedly told the hearing that he did not know the identity of one of the accused, Agustinus Sananay Kraar, when he pulled him into the police vehicle but only knew his name after they reached police headquarters. He told the court that he had not seen the document proclaiming the establishment of the Federal Republic of West Papua but confirmed that there was a banner  on which were inscribed with the words: ‘Let Us Affirm the Basic Rights of the Papuan Indigenous People, Today and in the Future’.

The second witness, Aamet Mahu told the court that he was in the vicinity of the venue of the KRP-III  on 19 October 2011 and was there on orders to handle security of the conference.

The defence team of the five defendants said that all the testimony given on that day in court was in way related to the charges in the indictment.
