Resjudicata

Sir. We are sunnihanafi family..in our family our grandmother was survived by only 2 daughters and her only son had predeceased her leaving behind a son and a daughter. The 2 daughters filed a declaratory suit against predeceased sons children seeking declaration that only 2 daughters are entitled to inherit the left over property of their mother,but court dismissed suit saying 2 daughters are entitled for 2/3rd share only rest 1/3rd will go to residuaries in this case predeceased son and daughter... hence we filed a new partition suit for seperate possesion of our 2/3 share in left over properties of our mother which are in joint possession with predeceased sons children.. Question: Whether filing a partition suit after the dismissal of declaratory suit seeking seperate possession of 2/3rd share of 2 daughters amounts to Resjudicata ?
