The petition contained the signatures of 100,732 voters. Under Section 256 of the Constitution, 50,000 signatures are needed to have a draft amendment considered by Parliament.
The petition campaign was launched on August 7 this year and gathered signatures at anti-government rallies and by mail.
ILaw manager Yingcheep Atchanont said the campaign aimed to reform the Constitution and end the power of the National Council for Peace and Order (NCPO).
