Samoa's Attorney-General has filed a complaint with the Supreme Court, claiming Monday's swearing in of the FAST party was unconstitutional.
The Supreme Court heard it for mention yesterday afternoon, and set down a hearing for Thursday at noon.
The attorney-general named the FAST party leader, incoming Prime Minister Fiame Naomi Mata'afa, all of its MPs and their lawyers as respondents.
In a statement last night threatening action, the attorney-general's office said those who conducted the ad-hoc swearing in ceremony held Monday afternoon had no legal authority.
