Use of 'Nidhi Limited' restricted unless formally declared; amendment enforces statutory naming safeguard for companies. The amendment inserts a proviso into rule 4(5) of the Nidhi Rules, 2014, providing that a company shall not use the name 'Nidhi Limited' unless it is declared as such under the statutory declaration mechanism; the rule change is made under the Companies Act and comes into force upon publication in the Official Gazette.
