In September 2013, it appeared that the Hydra had finally been slain: the long-running, complex and expensive Bell Group litigation had settled just before the hearing of an appeal to the High Court. However, just like the Hydra of myth, it appears that where one head of litigation is cut off, at least one other will grow. The High Court has just ruled in Bell Group N.V. (in liquidation) v Western Australia  HCA 21 that the Bell Group Companies (Finalisation of Matters and Distribution of Proceeds) Act 2015 (WA) (‘Bell Act’), under which the $1.7B settlement sum was sought to be distributed, is constitutionally invalid. The legislation was rushed through the Western Australian parliament last year, but last-minute amendments made in April this year were insufficient to save it. It seems likely that the Bell litigation will continue, as litigation had previously been both threatened and commenced after settlement and prior to the enactment of the Bell Act.
