Vorachai said the issue was not under the NACC’s authority. The anti-graft body’s pursuit of the case amounts to an attempt to override the higher authority of the legislative body that the MPs were elected to sit in, he said.
Vorachai said the bill the MPs had pushed for did not yield any benefits to anyone, contrary to people’s fears.
The amnesty bill was among several bills pushed in late 2013 before the military coup. Opponents alleged that the proposed legislation was intended to benefit certain figures including self-exiled former PM Thaksin Shinawatra.
One of the 40 MPs has filed a lawsuit demanding compensation from the NACC.
The court will hear the first testimony on the case in February.
