À la suite de l' adoption du règlement d' exemption en 1992, la plupart des notifications transmises à la Commission ont été retirées, mais pas toutes, vu que les parties concernées considéraient que le règlement ne répondait pas assez clairement à la question de savoir si leurs accords étaient éligibles à une exemption.
