Attorney General Mohamed Anil has asked the Supreme Court to declare that MPs who leave their party, joins another party or is expelled from the party will lose their seat.
AÂ first hearing took place Monday afternoon after the constitutional case was abruptly put on the apex courtâ€™s agenda in the morning.
It comes after ten ruling party lawmakers joined the opposition alliance to seek the removal of Speaker Abdulla Maseeh Mohamed. A no-confidence motion was submitted last week with 45 signatures from the 85-member house, signaling theÂ collapse of President Abdulla Yameenâ€™s previously unassailable pro-government majority.
Eight of the ten defectors have quit the ruling Progressive Party of Maldives in recent days amid rumours of the AG planning to seek a Supreme Court ruling to scuttle the July 24 no-confidence vote.
AG Anil reportedly told the court that MPs who switch parties after contesting on a party ticketÂ break their social contract with voters and abandon the ideology that their constituents backed. MPs crossing the floor is an undemocratic practice that poses aÂ threat to independence and sovereignty as lawmakers become subject to external influences, he contended.
MPs are stripped of their seats in India, Singapore, Bangladesh, and England if they switch parties, he noted.
Anil also accused the opposition of seeking to oust President Yameen on numerous occasions, including the 2015 May Day mass protest, the September 2015 blast on the presidentâ€™s speedboat, and an attempt to arrest the president with a fake warrant.
It is unclear if the ruling sought by the AG would apply retroactively.
Nine MPs from the Jumhooree Party, four from the main opposition Maldivian Democratic Party, and four independent MPs had switched to the PPM after the March 2014 parliamentary elections.
The PPM won 33 seats but went on to increase its parliamentary group to 48 by the end of 2016.
The Supreme Court case has sparked an exodus from the PPM withÂ MPs Abdulla Sinan, Saudhulla Hilmy, Abdulla Ahmed, and Ahmed Thoriq announcing their resignations.
MPs Saud Hussain and Mohamed Musthafa, two lawmakers from former President Maumoon Abdul Gayoomâ€™s faction of the PPM, also left the party on Monday after the Supreme Court hearing.
Three PPM MPs who sided with Gayoom in the partyâ€™s leadership dispute â€“ including his son MP Faris Maumoon â€“ were previously expelled by the partyâ€™s disciplinary committee. The PPM was split into rival factions when Gayoom lost a bitter struggle with his half-brother YameenÂ for control of the party.
In late May, the supreme court also declared itselfÂ the final authority to determine the validity ofÂ the parliamentâ€™s removal of the president, vice president, ministers, judges, auditor general, prosecutor general and members of independent institutions.
