25.—(2) (a) Every registered end year producer licensed by the Board to sell milk by retail, semi-retail or wholesale shall pay to the Board a contribution of such amount as the Board may determine in respect of every litre of milk (whether sold as whole milk or otherwise) of his own production which he has sold in the final trading period, or any part thereof, by retail, by semi-retail or by wholesale. The Board may determine different rates of contribution for different descriptions of milk and for the avoidance of doubt it is hereby declared that the Board may, in exercise of the power conferred upon them by this subsection, for any such rate fixed by them in that period determine in the first accounting period after Vesting Day that some other rate shall be payable. Such contributions shall be payable on such dates as may be fixed by the Board and shall be a debt due by the registered end year producer to the Board and recoverable by the Board accordingly. In determining the rate of any such contribution the Board shall have regard to the extent to which the prices determined by the Joint Committee for milk (whether sold as whole milk or otherwise) of the same description as that sold by the registered end year producer for the appropriate accounting period, as estimated by the Board, exceed the producers' prices for that period as so estimated by the Board.
(b)In addition to the contribution determined by the Board under subsection (2)(a) hereof, the Board may require registered end year producers, in respect of every litre of milk (whether sold as whole milk or otherwise) of their own production sold by them in the final trading period, or any part thereof, by retail, semi-retail or wholesale, to make contributions of such amounts as the Board may determine towards the expenses of the Joint Committee and towards the cost of advertising milk in the final trading period, or any part thereof.
(3) (a) Sale by retail means the sale by a registered end year producer, licensed as aforesaid, of milk (whether sold as whole milk or otherwise) of his own production by his own hand or by the hand of a member of his family or that of a person directly employed by him to domestic consumers.
(b)Sale by semi-retail means the sale by a registered end year producer, licensed as aforesaid, of milk (whether sold as whole milk or otherwise) of his own production by his own hand or by the hand of a member of his family or that of a person directly employed by him to a hospital, hotel, restaurant or such other class or classes of buyers (not being domestic consumers or persons carrying on business as distributors of milk or manufacturers of milk products) as the Board may determine.
(c)Sale by wholesale means the sale by a registered end year producer, licensed as aforesaid, of milk (whether sold as whole milk or otherwise) of his own production packed on his premises in retail containers and sold by him to a purchaser for subsequent retail sale. Provided that the Board may, at their discretion, fix the quantity of milk (whether sold as whole milk or otherwise) which may be sold by any individual registered end year producer by wholesale under the provisions of this section.
