Can you explain how a Proclamation can be extended for additional six-month periods by both Houses of Parliament?
The context explains a mechanism for extending the period of operation of a Proclamation beyond its initial six months. According to this procedure, a Proclamation that has already been approved by both Houses of Parliament can be extended further if a resolution approving its continuance is passed by both these Houses again. This additional approval will allow the Proclamation to remain in force for another period of six months from the date when it would have otherwise ceased to operate under this clause, but it cannot continue beyond three years in total.
