In May 2004, Health Minister Khaw Boon Wan informed Parliament that the NKF had treated 1,414 patients in 1999 and 1,512 patients in 2003.
In August 1997 and December 1998, NKF volunteer Archie Ong and aero-modelling instructor Piragasam Singaravelu respectively were hauled to court separately for defamation when both said that T.T. Durai had been flying first class.
Opposition politicians, notably Chee Soon Juan, have noted that the issues at NKF would probably not have been revealed if T.T. Durai had not sued the Straits Times.
