Commenting on how the Prevention of Corruption Act offers some protection such as the withholding of names and addresses of informants, SMU Associate Professor of Law Eugene Tan noted that certain disclosures may not be forthcoming without the level of assurance that legislation can provide. On subordinates suspecting their bosses of corruption, he said: “These are precisely the people in best positions to sense when something is amiss, but the power difference causes them to hold back on complaints. This is where greater assurance of protection will help." However, Associate Prof Tan also noted that laws meant to protect whistleblowers may also be abused by some to mount personal attacks. He said: “There must be sufficient sanctions and a clear definition of a ‘whistle-blower’ to prevent abuse."
