A bench of Chief Justice DY Chandrachud and Justice PS Narasimha asked NGO 'Citizens for Justice and Peace' and the states of Uttar Pradesh, Madhya Pradesh, Uttarakhand and Himachal Pradesh to apprise it about the status of cases challenging the state laws on conversion through marriage. "You all file a note indicating the status of cases, challenge to law, ordinance or amendment and stage of the proceedings before the respective High Court. We want to have conspectus of the matter. We have not taken a conclusive view but if all these cases are pari materia (on the same subject or matter) then we will transfer all of them here or if the proceedings are at an advanced stage, then we will allow the High Courts to proceed”, the bench said.
