Applicability of Chapter provisions to establishments, with electronic application, employee consent, deemed permission, and strict maintainability conditions. Rule 3 permits an employer to apply electronically for Chapter III or Chapter IV to be made inapplicable to an establishment, subject to written agreement by the employer and the majority of employees. The application must be decided within sixty days, and if no decision is taken within that period, permission is deemed granted from the expiry of sixty days. The rule further bars applications where the establishment has subsequently become covered, where five years of coverage have not elapsed, or where returns, dues, and self-certification requirements are unmet.
