The decision comes less than a month after Thaksin's sister, former Prime Minister Yingluck Shinawatra, was banned from politics for five years by the junta-appointed legislature stacked with former or serving officers of the military, which has twice toppled governments led by her family.
"We have found 250 MPs guilty of acting unconstitutionally. We will forward the case for impeachment to the national legislature," Wicha told reporters.
The NACC said the former MPs acted dishonestly. They face a five-year ban from politics if found guilty by the NLA.
The case aims at destroying the Shinawatra political machine, said Paul Chambers, research director at the Institute of South East Asian Affairs affiliated with Chiang Mai University.
"The NACC is forwarding the case to the military-dominated NLA. Thus we see here how the judiciary and the military cooperate to boost an arch-royalist agenda," Chambers told Reuters, adding that the case was an attempt to destroy the Shinawatra family and their allies.
A court ruled that efforts to change the composition of the Senate were an attempt to "overthrow" the country's democratic system.
Of the 250 lawmakers charged by the NACC, 223 are former Puea Thai Party lawmakers. Banning them would deliver a serious blow to the party ahead of the next general election, planned for 2016.
The latest crisis began in November 2013 and culminated in a May 22 coup.
