The Human Rights Protection Party (HRPP) has now lost a total of five seats and holds 20 compared to the election winning FAST party's 26.
Two cases were heard today, with another deferred until tomorrow.
Today's case against the Faatuatua I le Atua Samoa ua Tasi (FAST) party's Gagaemauga No 1 seat holder and Deputy Prime Minister-elect Tuala Tevaga Ponifasio was settled amicably, and withdrawn.
RNZ Pacific's correspondent in Samoa, Autagavaia Tipi Autagavaia, says the other was withdrawn but the seat will be contested again.
