However, the judicial jury system was met with inefficiencies, because it became harder for the jurors to decide if a person is guilty or not due to their lack of professional legal background. It was also harder for the jury to sentence people to death. Besides, the jury verdicts were decided not based on facts, evidence and law, but based on emotions, which allowed cases where people are clearly guilty as charged, yet escaped the penalties they deserved with lesser crimes or go scot-free, or cases of wrongful convictions or sentences or both. As such, the jury system was completely abolished with effect from January 1970 onwards, effectively making the murder trials of Tan Cheng Eng William, Freddy Tan Seng Keng and Ho Joon Toh as the last jury trials conducted for capital cases in Singapore. The capital cases were instead heard before two judges in the High Court; this practice lasted from 1970 to 1992.
