Though claiming ignorance of this as a doctrinal position, Toole as much as admitted the doctrinal position remains in effect because he offered some of the same explanations for why the position was invoked in the first place. So the doctrinal position of TWS remains intact, which means the part dealing with statements made under a sworn oath also remain intact.
