What is the significance of the phrase "nothing in article 19 shall restrict the power of the State as defined in Part III" during an emergency?
During an emergency, the phrase "nothing in article 19 shall restrict the power of the State as defined in Part III" signifies that the restrictions imposed by Article 19, which safeguards fundamental rights such as freedom of speech and expression, assembly, movement, etc., do not apply. The State has the power to make any law or take executive action without being limited by the provisions contained in Article 19. However, this power is only valid for the duration of the emergency, and any law enacted during that time will cease to have effect as soon as the emergency ends.
