The alleged plotters, Malele Atofu Paulo also known as King Faipopo and Lema'i Faioso Sione, have been in custody for six months after police arrested them last August.
Malele and Lema'i were released on strict conditions including not to interfere with Tuilaepa or police witnesses.
They are also ordered not to post on social media anything that could interfere or relate to the pending trial.
