67Furthermore, those considerations distinguish the present case from those which gave rise to Commission Decision 85/74/EEC of 23 November 1984 relating to a proceeding under Article [81 EC] (Case IV/30.907 — Peroxygen products) (OJ 1985 L 35, p. 1), Commission Decision 86/398/EEC of 23 April 1986 relating to a proceeding under Article [81 EC] (Case IV/31.149 — Polypropylene) (OJ 1986 L 230, p. 1), and Commission Decision 89/191/EEC of 21 December 1988 relating to a proceeding pursuant to Article [81 EC] (Case IV/31.866, LdPE) (OJ 1989 L 74, p. 21) respectively. Those decisions relied upon by the applicant concern situations where there was a transfer of activities affected by the infringement between groups of undertakings without structural links and therefore do not bear any similarity with the present case.
