Justice B K Sharma, hearing a writ petition stayed the speaker's order disqualifying the MLAs on December 15 and issued notice to the respondents.
He fixed January 7 as the next date of hearing.
The writ was filed by dissident Congress MLAs Pema Khandu and 13 of his colleagues, who were disqualified by Rebia under 10th Schedule of Constitution.
They contended that the order of disqualification was passed by the speaker in violation of natural justice without giving them an opportunity of hearing.
