TAIPEI (Taiwan News) — The Constitutional Court rejected an appeal brought by three death row inmates on Friday, citing insufficient evidence.

Death row inmates Li Te-jung (李德榮), Peng Chien-yuan (彭建源), and Shen Wen-pin (沈文賓) submitted their appeal to the Constitutional Court after earlier administrative appeals failed, per CNA. In the appeals, the trio argued their constitutional rights were breached.

In its rejection decision, the Constitutional Court noted the trio requested a pardon from former President Tsai Ing-wen (蔡英文) in 2022. Tsai did not respond to the request, after which the group made two failed appeals to administrative courts requesting pardon or commuted sentences.

The High Administrative Court ruled that only the Constitutional Court had jurisdiction over the case in the first appeal. The Supreme High Administrative Court rejected the second appeal, after which the trio made a third appeal to the Constitutional Court.

Li, Peng, and Shen claimed the death sentence deprived them of the right to life. They also argued their constitutional rights may have been infringed because of inadequate legal procedures that undermined their ability to seek pardon.

The Constitutional Court said the trio did not show the interpretation of the law in their original case had deprived them of basic constitutional rights. It said the case was without legal basis, and rejected it.

Li, Peng, and Shen were sentenced to death for the murder of one, five, and two people respectively in separate cases. Each has said the murders were unintentional or blamed mental issues, according to the Taiwan Alliance to End the Death Penalty.
