Ong-arj said Democrat leader Abhisit Vejjajiva called the meeting after the chief of the National Council for Peace and Order issued an order to partially relax the political party ban.
Ong-arj said the Democrat’s charter required the executive board to be informed of what decisions would be made during a party assembly.
Ong-arj said the assembly would need to amend the party’s regulations on the election of the party’s leader and executives.
He said Abhisit has proposed extending to non-executive members the right to elect the party leader.
