The court on Sunday had declared the Head of State, Tuimaleali'ifano Va'aleto'a Sualauvi II, acted unlawfully on Saturday in suspending parliament.
The extraordinary session of the Supreme Court found in favour of the newcomer Fa'atuatua i le Atua Samoa ua Tasi (FAST) party's challenge to Tuimaleali'ifano's edict voiding his previous call for parliament to convene tomorrow.
FAST was expected to declare its majority when parliament met, and announce Samoa's first woman prime minister Fiame Naomi Mata'afa.
