How often can a resolution approving the continuance be passed by both Houses of Parliament for a Proclamation to remain in force?
The context states that the Proclamation will continue in force for a further period of six months from the date on which it would otherwise have ceased to operate under this clause, if and so often as a resolution approving its continuance is passed by both Houses of Parliament. So, theoretically, there is no specified limit on how often such resolutions can be passed for the Proclamation to remain in force.
