Several members of organisations in the public health sector have tendered their resignation ahead of the National Anti-Corruption Commission (NACC) rule obliging them to declare their assets and liabilities taking effect next month.

The National Health Security Board (NHSB) held a meeting Monday to appoint four new advisory members after those in the positions resigned.

Public Health Minster Piyasakol Sakolsatayadorn, who chairs the NHSB, said in addition to the four resigned members, he had been made aware that Bangkok governor Aswin Kwanmuang had also decided to step down as a board member.

Referring to reports that members of other organisations in the public health sector are resigning from their positions, Dr Piyasakol said: "I think they are keeping watch on how the NACC might adjust the rule, particularly whether these [assets and liabilities] must be made public.

"This is likely to be made clear by the end of the month," he added.

The rule requires senior officials holding executive positions such as department deputy director-general, university rector and other equivalent positions to declare their assets and liabilities. It also obliges their spouses and children to submit declarations of their assets and debts to the NACC.

It was earlier scheduled to come into force on Dec 2 but the NACC deferred it to Jan 31, following fierce criticism.

Dr Kittinan Anakamanee, CEO of the Healthcare Accreditation Institute, said three out of the organisation's eight advisory board members had tendered their resignation.
