Deputy Public Prosecutor James Chew said life imprisonment would not be disproportionate to the man’s culpability and the gravity of the offence, which warrants a sentence at the high end of the sentencing range.
The prosecutor noted that the court has the discretion to enhance an offender’s sentence in the absence of an appeal by the prosecution if the interests of justice call for such an increase.
The three-judge court, led by Chief Justice Sundaresh Menon, dismissed the man’s appeal, rejecting his arguments that he has shown remorse and that he should be given a sentencing discount for pleading guilty.
Chief Justice Menon said the court will issue detailed grounds to explain its decision in due course.
The judges, who also included Justice Steven Chong and Justice Judith Prakash, also imposed 12 strokes of the cane, which were part of the original sentence.
However, the man will not be caned as he was medically certified in 2024 to be permanently unfit for caning, on account of his degenerative disc disease and a disc compression.
The High Court had allowed the name of his daughter, Ayeesha, to be published.
Ayeesha was five years old when she died from a head injury after her father rained blows to her face. Her brother was then four.
The man had Ayeeseha and her brother from his previous marriage. He has three other children with his second wife, whom he married in 2015.
The man, who had martial arts training, started abusing Ayeesha and her brother in 2015.
He hit the two children and left them malnourished.
From February to October 2016, the couple confined the children in a “naughty corner”, which was barricaded with a bookshelf and a wardrobe to keep them there.
The children were let out only for meals and baths.
The man also installed a CCTV camera to monitor the children.
The children were confined naked in the toilet for nearly 10 months, from October 2016 to Aug 11, 2017.
