Congress will move Supreme Court against the appointment of Manohar Parrikar as Goa chief minister on Tuesday.
The apex court will have a special hearing tomorrow. The grand old party's decision comes close on the heels of the BJP's decision to stake claim to form government in the coastal state on Sunday evening.
Parrikar stepped down as Defence Minister after he was appointed as the chief minister by governor Mridula Sinha.
Parrikar has been given 15 days to prove majority support after he takes oath tomorrow.
