Opposition parties and rights groups in Malaysia have launched a campaign to free jailed former deputy prime minister Anwar Ibrahim, who is serving two consecutive terms totalling 15 years for corruption and sodomy. The country's highest court is preparing to hear an application to review his conviction on the grounds that his trial was deeply flawed. Last July, the Federal Court upheld Anwar's conviction and six-year sentence for corruption, but in an about-turn it has agreed to hear arguments for a review. The review, which had been scheduled for today has been postponed at the government's request to allow for a full bench of five judges to hear the application. A new date would be fixed soon, said court registrar Kalyana Kumar. The court, if it does not reject the application outright, could also order a re-trial. If his application were rejected, Anwar would remain behind bars until 2009, dashing any hopes for a political comeback. Last Friday, lawyers rushed to file fresh papers offering new evidence. They say public prosecutors attempted to extort fabricated evidence from a witness. The evidence, in the form of an affidavit filed by a past president of the Bar Council, relates to an attempt to obtain a 'confession' detrimental to Anwar from a former friend who was at that time facing a death sentence for firearms possession. Prosecutors have denied the allegations. Next Monday, another court will hear Anwar's long delayed appeal against a nine-year sentence for sodomy. Anwar's supporters are campaigning to have him released on bail on April 14, arguing that on this date his six-year sentence would end after a one-third remission for good behaviour - an argument rejected by the Prisons Department. The supporters have been holding meetings in houses, offices and mosques to avoid the ban on open-air political rallies. Little of these events are reported in the country's mainstream media, representing a setback for the political opposition. Observers also see the retirement of the reformist minded Chief Justice Mohamed Dzaiddin as a blow for judicial independence. He threw Anwar a legal lifeline when he ordered the judicial review, but the final outcome is now in the hands of his successor, Justice Ahmad Fairuz, who took over yesterday. Raja Petra Kamaruddin, head of the Free Anwar campaign, said: 'Anwar is denied bail, has to serve his two sentences consecutively and worst still, his nine months in jail before he was charged is not counted.'
