You will need to use the exists keyword.
 
Without digging around for the manual you need to do something like:-
 
when
exists (
    LineItem( $parent: parentId )
    LineItem( id != $parent )
)
then
    // raise the exception
end

Is 30 correct, you are not clear. Did you want one exception for any number
of violations?
