Traces how the Court of Justice built the concerted-practice doctrine: from ICI (Dyestuffs), para 64 (“knowingly substitutes practical cooperation for the risks of competition”) and Suiker Unie, paras 26 & 173–174 (“each operator must determine independently its market policy”), through parallel-conduct proof (Züchner, Wood Pulp II), information exchange (John Deere, Asnef-Equifax), concertation + market conduct + causality & presumption (Anic, Hüls, Aalborg), object + single-meeting doctrine (T-Mobile, Dole), to platform tacit assent (Eturas), attribution (VM Remonts), duration/distancing (Eltel) and vertical/hub-and-spoke (Super Bock). Earliest case on top, latest on bottom — ordered by exact judgment date (day precision). Arrows run from a later case to the earlier case it cites on the concerted-practice point. Click any case to bold all directly connected cases.
