The nine Congress MLAs challenged their disqualification by speaker by Assembly speaker Govind Singh Kunjwal in March this year.
They were disqualified by Speaker after the rebel Congress MLAs joined hands with the BJP during proceedings on the Appropriation Bill on March 18.
The court's decision has brought cheers on faces of those who have been supporting Harish Rawat.
However, the MLAs have now approached the Supreme Court for urgent hearing against high court's decision dismissing their plea which challenged their disqualification.
Supreme Court is likely to hear their plea at 2 pm.
