Today could be a critical moment in the Anwar Ibrahim sodomy trial as the head of the Serious Crime Unit from the Chemistry Department Dr Seah Lay Hong takes the stand.

Yesterday, Seah, who performed the DNA tests, was on the stand for less than five minutes before erratic power supply during the afternoon at the Kuala Lumpur High Court forced an adjournment.

The court had heard several surprising revelation yesterday, particularly that the pro-forma form used by doctors had stated the alleged incident involving sodomy complainant Mohd Saiful Bukhari Azlan only involve “attempted sodomy” and “attempted oral sex”.

Although former Hospital Kuala Lumpur doctor Dr Khairul Nizam Hassan insisted that Saiful had claimed he was sodomised and was asked to perform oral sex, the defence led by Karpal Singh managed to raise doubts.

Also present in court today is a representative from the Australian Embassy. Other observers includes two Australian specialists Dr David Wells, a forensic pathologist, and Dr Brian McDonald, a DNA specialist, who are hired by Anwar's defence team.
