Today, since the amendment of the Criminal Procedure Code in 1992, all capital cases are heard by a single judge in the High Court instead of two judges. After conviction and sentencing, the sentenced has one appeal to the Court of Appeal. If the appeal fails, the final recourse rests with the President, who has the power to grant clemency on the advice of the Cabinet. In exceptional cases since 2012, the Court of Appeal would be asked to review its previous decisions in concluded criminal appeals where it was necessary to correct a miscarriage of justice, most of which involved drug cases attracting the death penalty. The exact number of successful appeals is unknown. In November 1995, one Poh Kay Keong had his conviction overturned after the court found his statement to a Central Narcotics Bureau officer was made under duress. Another case was Nadasan Chandra Secharan, who was initially convicted of murder and sentenced to death by the High Court in June 1996, but later acquitted of murder by the Court of Appeal in January 1997, after they found the evidence against him was insufficient to show that he had murdered his lover Ramipiram Kannickaisparry. A more recent case was that of Ismil bin Kadar, who was initially sentenced to death for a 2005 robbery-murder case in Boon Lay, but eventually acquitted of the crime as the Court of Appeal found that based on the evidence, Ismil was not involved in the case and that it was solely his younger brother Muhammad bin Kadar who was responsible for the robbery and murder; Muhammad was subsequently executed in April 2015. Successful clemency applications are thought to be even rarer. Since 1965, the President's clemency has been granted six times to death row inmates, whose sentences were commuted to life imprisonment (not counting the clemency pleas of the underaged offenders serving TPP). The last clemency granted to a death row inmate was in April 1998 when then President Ong Teng Cheong pardoned a 19-year-old death row inmate and convicted murderer Mathavakannan Kalimuthu, and reduced his sentence to life imprisonment.
