I refer to your memorandum dated 7th January, 1946, forwarding for consideration a plan for the post-war organization of the potato industry. The plan appears to comprise four principal matters, as follows:
- Control of production of potatoes (including licensing of growers and allocation of acreage);
- Marketing of potatoes;
- Maintenance of quality of potatoes;
- Fixing of prices of potatoes.
The Commonwealth has no constitutional power with respect to (a).
