Our view that an instrument does not fall within IHTA84/S142
if it further redirects any item or part of an item that has
already been redirected was upheld by Knox J in Russell v IRC
(1988) STC 195. Accordingly
You should refer to TG any case where this appears to apply, or any case in which there is an IoV and a disclaimer (whatever the order) affecting the same property on the same death.
