Ex-premier Samak Sundaravej and former foreign minister Noppadon Pattama were among those ex-ministers.
The anti-graft agency voted to charge them for negligence and violating Article 190 of the Constitution, which states that any treaty that would affect Thai territories or sovereign rights must be approved by the National Assembly, said Somlak Jadkrabuanphol, who was in charge of the investigation that led to yesterday's decision.
The ex-ministers attended a Cabinet meeting that resolved to endorse the agreement signed by Noppadon and Cambodia's Deputy Premier Sok An.
The Cabinet members who did not attend the meeting in question were not indicted.
Somlak said the NACC would inform those people in writing so that they can defend themselves against the charges, either in person or in writing.
