Up to 40 percent of the recommendations made by Royal Commission of Inquiry (RCI) into the death of Teoh Beng Hock have been implemented by the government.

This is according to the former RCI chairperson James Foong, when he was asked if he was satisfied with the actions since the commission published its report in 2011.

"RCI's role is to find out who is right and then make recommendations. Many have failed to realise that the importance of making recommendations, which is good for the future development of the country," Foong (photo) said.

While admitting that the government might not be able to carry out 100 percent of the recommendations made by the RCIs, he said that in this case, at least 20 percent to 40 percent have been implemented.

"In Teoh's case, the improvement had been done in the interrogation (process), where they cannot question (the witnesses and suspects) at the higher floors," he said.

"If you ask me personally if I am satisfied, a commission had been conducted and recommendations have been made. It is up to the government and other parties to move forward to ensure this would not happen again.

"As to why there were no prosecutions, it is not up to RCI, especially the chairperson, to comment," said Foong, who is a former Federal Court judge.

Teoh was the political aide to Seri Kembangan assemblyperson Ean Yong Hian Wah. He was found dead at the then Selangor MACC headquarters on July 16, 2009, where he had been held overnight for interrogation.

The RCI established that Teoh fell to the ninth floor landing from MACC's office on the 14th floor. He was survived by a fiancée and a son.

After much public outcry, the Najib administration established the RCI to investigate the cause of Teoh's death.

It concluded that Teoh was driven to a suicidal state due to the aggressive interrogation methods.

The RCI recommended that the MACC reprimands the three officers who carried out the interrogation. However, this was not carried out.

The Court of Appeal had ruled in 2014 that Teoh had died of a fall that could have been accelerated by unlawful actions of persons unknown, including by MACC officers, and ordered the police to investigate.

Following the verdict, MACC agreed to pay RM600,000 to Beng Hock's family to settle a negligence suit brought by his family.

However, there are still no criminal proceedings to date. Instead, the Attorney-General's Chambers said it found no criminal elements in Teoh's death.
