Pheu Thai member Wicharn Meenchainant said party candidates will lodge complaints against the EC for negligence of duty and abuse of authority.
He said the EC has made no progress in attempts to complete the polls, despite a constitutional requirement that the House of Representatives be convened within 30 days of a general election.
Mr Wicharn said the party will launch a campaign to have the election declared void if it cannot be completed on time.
Caretaker Information and Communication Technology Minister, Anudith Nakornthap, said the delayed election process has hindered the government. He noted there are several bills pending parliamentary scrutiny.
Meanwhile, EC member Somchai Srisuttiyakon said the EC will ask the government to clarify its decision not to issue a royal decree for a new election in 28 constituencies of eight southern provinces where there were no candidates.
The government needs to make clear it has resolved not to issue the proposed decree so the EC can ask the Constitution Court to intervene, he said.
Mr Somchai said the caretaker government is following a suggestion from its legal adviser, the Council of State, not to issue the decree.
The Council of State’s opinion is likely to go to the cabinet today, he said.
Mr Somchai insisted that a meeting planned for March 7 to find a solution to the incomplete election will proceed, even though the government might not attend.
He said the government should drop its intention to seek talks with the EC over plans to raise funds by issuing government bonds to pay debts to farmers. He said the EC has no authority over the issue.
