Taiwan’s high court has upheld the death sentence passed last year on Cheng Chieh. In 2014, Cheng killed four people and injured 22 others in a random knife attack on the Taipei Metro system.
The high court rejected an appeal of the sentence and handed down its ruling on Friday.
The high court ruled that there is nothing illegal about upholding a death sentence under the International Covenant on Civil and Political Rights or the International Covenant on Economic, Social and Cultural Rights. Taiwan signed the two human rights conventions into law in 2009.
The high court also said that Cheng was arrested at the scene of the crime with clear criminal evidence and that he was not insane when he committed the crime.
The high court also said it will not avoid approving death sentences before Taiwan reaches a consensus on the abolition of capital punishment.
The husband of one victim responded to the ruling Friday by saying that justice has been served.
