subdelegated legislation

subdelegated legislation Legislation made under powers conferred by delegated legislation or by subdelegated legislation itself (in which case it is technically sub-subdelegated legislation). Subdelegated legislation is quite common (as when the parent Act authorizes a minister to make regulations and these in turn authorize others to make orders), but sub-subdelegated legislation is rare (though examples have existed in wartime); the chain has not in practice been further extended. Subdelegated legislation is not subject to any form of parliamentary control but it is subject to judicial control by means of the doctrine of ultra vires.
