Section 46 deals with authentication of orders and documents of the Authority, ordinarily requiring signature or authentication by prescribed officers, which helps courts and affected persons verify the legality of actions taken under Chapter VIII. Section 47 declares members, officers and servants of the Authority to be public servants, bringing them within the purview of the Indian Penal Code’s provisions on public servants and related offences.[4][2]

Section 48 restricts the jurisdiction of civil courts in respect of matters that the Act entrusts exclusively to the Authority or to designated appellate bodies, thereby preventing parallel litigation from obstructing planned development, though constitutional remedies under Articles 226 and 32 remain untouched. Section 49 requires previous sanction of the Authority or State Government (as specified) for prosecutions under the Act, which acts as a filter against frivolous or excessive criminal proceedings.[10][2]

Sections 50 to 54 complete the chapter with protection of action taken in good faith, power of delegation of functions by the Authority, savings for certain actions or properties, exemptions for specified areas or undertakings, and provisions deeming plans to stand modified in identified circumstances. These provisions are typical of modern planning and development legislation and are intended to provide stability and flexibility in implementation while preserving accountability.[19][18][3][2]
