After gunning down the DAP, the People's Alternative Party (PAP) has urged the Home Ministry to probe the alleged wrongdoing of the Registrar of Societies (ROS).

This follow's the party's chairman Zulkifli Mohd Nor urging Home Minister Ahmad Zahid Hamidi on April 22 to explain why the DAP was allowed to contest in the Sarawak state polls.

PAP national organising secretary Rahmad Isahak said the Home Ministry should form an internal team to investigate how ROS could allow DAP to contest in the Sarawak election.

"How could ROS allow DAP candidates to contest in the 11th Sarawak state polls when the agency does not recognise the party's central executive committee," Rahmad said in a statement.

"Something appears to be wrong when ROS' own order to DAP under Section 16 (1) of the 1996 ROS Act failed to be applied to DAP," he added.

"This issue involves public interest as ROS has failed to act against DAP although three years have passed," he said.

In September 2013, DAP re-elected a new central executive committee but ROS has refused to ratify the new leadership line-up.

ROS said it was still receiving "new complaints" about the DAP’s re-election exercise.

Rahmad claimed that Penang DAP chief Chow Kon Yeow on April 30 this year had verified that ROS has not recognised the party's CEC.

He accused ROS of keeping silent towards the PAP's queries about its conduct towards the DAP.

He also said that DAP's 31 candidates in the Sarawak polls were "illegal" as their letters of appointment (watikah) were issued by a CEC that was not recognised by ROS.

"This has given rise to negative public impression against the ROS," he said.

"So please initiate an internal probe to see who is the black hand behind the ROS, and why the agency has given the DAP such special treatment," he added.
