They sought an appeal against the original sentence on the grounds that the original trial judge had drawn unwarranted inferences from
circumstantial evidence and had erred on several points. Other arguments of the appeal revolved around the credibility of the arresting officer's testimony, and questions of whether Barlow and Chambers acted with a "common purpose" in trafficking in the drugs. On 15 December 1985 they were transferred to
Kuala Lumpur for their appeal to the
Malaysian Supreme Court. There they were imprisoned in
Pudu Prison. Barlow continued to profess his innocence.
Pudu Prison had been built in 1895 to hold about 700. By 1986 it held around 6,000 prisoners, almost 50 of whom were drug dealers sentenced to death. Singh attempted to have Galbally charged with contempt. The day after the row, Galbally was asked for, and submitted, an apology to the court for his words in court. The appeal court on 18 December 1985 upheld the trial judge's decision to invoke the death penalty because the amount of the drug carried was in excess of the cut-off point used to distinguish users from traffickers. On death row, Chambers had taken up biblical studies with a Western Catholic Missionary. He broke down and wept in her arms in the dock when three appeals judges upheld the conviction. Galbally was not in court for the final decision of the appeal; Australian officials reported that he had left Malaysia on the night of 17 December after apologising to the Supreme Court over the row over contempt. After the result was publicised Galbally suggested that Barlow would have been found not guilty had the medical evidence he wanted introduced been admitted by the court. The evidence he wanted heard at the appeal was that Barlow had a nervous shake; the prosecution had used Barlow's shake at the time of his arrest as grounds for his guilt. After the rejection of the appeal, Australia's Foreign Minister Bill Hayden contacted the Governor of Penang asking that the sentence be commuted to imprisonment on humanitarian grounds. Hayden stated that "I have always been and remain firmly opposed to capital punishment, and accordingly I will be pressing the presentation of this appeal for clemency with a great sense of urgency." Through the ordeal of Barlow and Chambers, their mothers, Sue Chambers and Barbara Barlow, publicly supported the defence of innocence. However, in a joint letter to the
Yang di-Pertuan Agong (Malaysian head of state)
Sultan Iskandar pleading for their lives, they acknowledged their sons' guilt, saying they "regretted their wrongdoing." ==Execution==
