Panel chairman Seri Suwanpanont met Monday with the Constitution Drafting Commission to submit the plan for consideration and inclusion in the new charter.
The Lower House of Parliament, he said, should be made up of constituency MPs only, elected from large wards under singlemember districts. That would, in theory, make votebuying more difficult.
The partylist system should be dropped because lists were often filled with greedy people who invest to enter politics and seek to profit, he said.
