The chairman leader of the Tautua Samoa party says he's disappointed the government has gone to such lengths to amend the country's electoral act.
Two bills were passed by parliament recently, one relating to an amendment to the Constitution and the other to the electoral act.
The prime minister, Tuilaepa Sailele Malielegaoi, says the two bills introduced are aimed at preventing party hopping in the future.
He also says the measures ensure that parties in the future will be strengthened and that members will abide by the party.
But the chairman of Tautua Samoa, Lealailepule Rimoni Aiafi, says the government's latest action is heading in the wrong direction.
"We were very disappointed and very sad with how low and how far now gone to with the abuse and the misuse of power they have, we are very disappointed."
Lealailepule says the party will be meeting with its lawyers to decide its next step.
