According to a report by the Star Online, Jabing, 31, had his bid unanimously thrown out by the Court of Appeal.

We Believe in Second Chances founder Kirsten Han said the appellate court made its decision today.

“Stay of execution lifted, sentence of death upheld,” she told the Star Online.

The 31-year-old from Ulu Baram, Sarawak, was found guilty of killing a Chinese construction worker with a tree branch back in 2008 during a robbery attempt.

Jabing was sentenced to death in 2010.

In 2013, the Singapore government amended the mandatory death penalty that gave judges the discretion to choose between death and life imprisonment with caning for murder, as well as certain cases of drug trafficking.

In August 2013, following revisions to the mandatory death penalty laws, the High Court sentenced him to life and 24 strokes of the cane instead.

The prosecution challenged the decision before the Court of Appeal, which again sentenced Jabing to death in a 3-2 majority decision earlier this year.

On Oct 19 last year, Singapore president Tony Tan rejected a clemency petition.

Jabing was scheduled to be executed on Nov 6, but received a stay the day before, after his lawyer filed a motion raising points of law about the case’s handling.

Jabing’s mother and sister, who were present in court, sobbed loudly upon hearing the verdict.
