It was felt it would be unfair if the new arrangements applied to existing leases, many of which are held by small farmers who would be penalised excessively. It was also felt that, because it was such a fundamental change which may be subject to a legal challenge, it would be better if the new arrangements came into operation from 12 October. I am not saying I received legal advice to that effect but that was deemed to be fairer. Existing leases will not be affected. If more milk is transferred to the temporary leasing scheme — there are three tranches — as the Deputy knows, priority will be given to smaller producers. In the second and third tranches almost all of the milk available will be offered to producers with quotas of less than 30,000 gallons.
