There was a doubt earlier whether intercaste marriage can be registered under this rule. At that time Government clarified that intercaste marriages can only be registered under Special Marriages Act. But now it is clarified that all marriages can be registered under this Rule irrespective of whether it is a intercaste or inter religious marriage.
The Hindu Marriages can also be registered under Hindu Marriages Act.
