Section 18(7) marks the endpoint of the transitional employment regime: once the option period (maximum two years, per Section 18(2) and its proviso) lapses, all transferred officers and employees who chose to remain (i.e., did not opt out under Section 18(2)) become fully governed by the Authority's OWN rules and regulations on service conditions - not the erstwhile IAAI/NAA rules, not general Central Civil Services Rules, and not a 'most beneficial' comparative standard. This finally completes the personnel integration process that began with the divisional structure under Section 18(1), culminating in a unified service regime under the Authority's own regulatory framework.
