"Madam, please. This matter has not travelled to this court," a bench comprising Chief Justice Dipak Misra and Justices A M Khanwilkar and D Y Chandrachud said when activist and author Madhu Kishwar raised the matter during the hearing.
Kishwar said that such types of offences were "hate crimes" and needed to be dealt with sternly.
The court today asked khap panchayats not to behave like the conscience keeper of society, pointing out that a marriage between two adults was governed by the law.
