The armed intrusion in Kampung Tanduo, Lahad Datu, occurred between February 12 and April 10, 2013, resulting in the deaths of nine security personnel [1, 2].

In 2024, the Federal Court of Malaysia upheld death sentences for seven men, including a nephew of Jamalul Kiram, for waging war against the Yang di-Pertuan Agong related to the Lahad Datu intrusion [1, 2].

Attorney-General Tan Sri Mohd Dusuki Mokhtar, who acted as deputy public prosecutor during the trial, described the case as a test of Malaysia’s justice system and its role in upholding sovereignty. He said, "There are security personnel who are willing to risk their lives to defend the country. After that, investigators, prosecutors, judges and many others each have their own responsibilities to ensure that justice is upheld" [2].

Tan Sri Mohd Dusuki emphasized that the prosecution carefully based the case on law and evidence, ensuring a transparent, fair, and impartial process despite the sensitive national security context. "A sovereign nation must be firm in protecting its security while ensuring that those accused of threatening national security are dealt with through a transparent, fair and impartial legal process," he said [2].

The case involved many accused persons, numerous witnesses, and extensive evidence requiring meticulous examination. "We were dealing with a complex case involving many accused, a large number of witnesses and evidence that had to be examined very carefully," Mohd Dusuki noted [2].

The Federal Court’s affirmation of the death sentences marks a firm legal conclusion to the events surrounding the Lahad Datu intrusion. The ruling reaffirms the authority of Malaysia's legal system in addressing challenges to the nation's sovereignty.

No further appeals appear pending, setting the stage for the enforcement of the court's decisions.
