“12.22 There is no limit to the number of persons who can be claimants or defendants to an action. There is therefore no impediment to a large number of claimants suing together or to a large number of defendants being sued together, but the multiplicity of parties, all of whom exercise their right to participate in the proceedings, may hinder the effective resolution of a dispute by causing duplication and confusion. Yet, it might be equally inefficient if each of a multitude of claimants with similar cases were required to establish their claims independently of each other, because it would require the court to deal with identical issues many times over. As Uff observed, two different sorts of interest may arise in the multi-party proceedings context. One is the true collective interest, where all those concerned share a single common interest (e.g. pollution; anti-discrimination). The second arises where individual substantive rights happen to be shared by several persons relating to a single event or similar transactions (e.g. personal injury claims following mass disasters; product liability claims). The procedural process suitable for administering one such sort of claim is not necessarily suitable or most appropriate for administering the other. AccordinglyCPR 19 provides two principal devices for handling multi-party actions. One is the representative action. The other is the group litigation order…”
“8. The Claimants were direct or indirect purchasers or both of air freight services from the Defendant and also from one or more of the undertakings identified in paragraph 4 above between December 1999 and March 2006. As such they are representative of all other direct or indirect purchasers of air freight services from the Defendant and also from those undertakings between December 1999 and March 2006.”
“By virtue of the inflated prices, the direct or indirect purchasers, including the Claimants, have suffered losses, including losses, under one or more of the following three heads: (1) the inflated element of the price, in so far as it was passed on to them [and not passed on by them],[ and/or] (2) loss of sales volumes in so far as the inflated price was passed on by them to their own buyers, and (3) loss of sales volumes of other products as a result of brand damage.”
“10. In the circumstances the Claimants claim on their own behalf and on behalf of all direct or indirect purchasers of air freight services from the Defendant and from the undertakings identified in paragraph 4 above between December 1999 and March 2006 a declaration (1)that the Defendant was a party to the agreements or practices described in paragraph [2]; (2) that the object or effect of those agreements or practices was as described in paragraph 3; (3) that the agreements or practices spanned the period between December 1999 and March 2006, as described in paragraph 4; (4) that the agreements or practices involved one or more of the undertakings identified in paragraph 4; (5) that the object or effect of the agreements or practices was to inflate the prices at which airfreight services were supplied to purchasers above those which would have prevailed had there been no such agreements or practices, as described in paragraph 6; (6) that the agreements or concerted practices constituted infringements of Article 81(1) EC (Now Article 101 of the Treaty on the functioning of the European Union), Article 53 of the EEA Agreement andsection 2 of the Competition Act 1998 , as described in paragraph 7; and (7) that damages are recoverable in principle from the Defendant by those purchasers in respect of each of the three types of loss described in paragraph 9.”
