The Supreme Court of India has deemed certain sub-rules of the Bihar Registration Rules, 2019, invalid. These rules required proof of mutation, such as Jamabandi, for property registration, which the court found to be an arbitrary precondition. The court stated that demanding proof of mutation effectively required evidence of title, exceeding the Registration Act's scope and infringing on the right to property. It clarified that registration of a transfer deed is separate from establishing title, a matter for civil courts, not registration offices.
