Sources said that the opinion was sought by Governor Ch Vidyasagar Rao from the Attorney General who has cited the 1998 Supreme Court judgement in the Jagdambika Pal case in which the apex court had ordered a floor test in the Assembly to determine who among the two claimants -- Pal and Kalyan Singh -- had majority for chief ministership of Uttar Pradesh.
The opinion, the sources said, has stated that "he (Governor) should call a special session within a week's time and have a composite floor test as was ordered by the Supreme Court in the Jagdambika Pal case".
The opinion on floor test was given as the two claimants are from the same party and they will be pitted against each other to determine who commands majority support in the Assembly, the sources said.
