Pawaskar was sworn-in late Wednesday night by Governor Mridula Sinha, hours after he along with another legislator Manohar Ajgaonkar broke away from the Maharashtrawadi Gomantak Party (MGP) and joined the BJP.
A first-time MLA, Pawaskar won from the Sanvordem constituency of South Goa in the 2017 polls.
Ajgaonkar and Pawaskar split from the parent party in the early hours of Wednesday, formed their own legislature wing and then merged it with the BJP, which is heading the coalition government in the coastal state.
The MGP, Goa's oldest regional party, had won three seats in the 2017 assembly polls. Now, the outfit, which once ruled Goa, is left with only legislator - Dhavalikar.
