I et notat med overskriften »1989 Issues and Objectives«, er det anført, at det skal undersøges, om meromsætningsrabatterne er lovlige, ligesom alternativerne skal tages under overvejelse.
ICI's own documentation shows however that it was aware that its rebate system was of questionable legality: a note headed '1989 Issues and Objeaives' reads 'consider legality of top-slicing and alternatives'.
