"No registering authority under the Registration Act shall register any document in respect of any land which has been notified as water body in the revenue records of the State," the Madras High Court ruled on Thursday. "The authorities concerned should mandatorily obtain a statement from the applicants, who want to register their property or seek approval for the lay-out or building construction or assessment of property tax or electricity or water connection, that the property concerned is not located on a water body," the first bench of Acting Chief Justice MN Bhandari and Justice P D Audikesavalu said.
