Evidence that it was only intended to last for the duration of the war
“All we have to do at the moment is to give the Government such powers as are necessary for the specified purposes for which they ask for them. They ask for them in order to regulate the sale and supply of intoxicating liquor in any area where they think it should be controlled by the State, on the ground that War material is being made, or loaded, or unloaded, or dealt with in transit. That is the primary and the great ground of necessity put forward. It is really in connection with the supply of munitions of war that this Bill is introduced. When the War comes to an end that special necessity will come, to an end; the real reason for the Bill will be at an end, and the sooner we can stop our liabilities in the matter the better it will be.”
