This guidance note proposes the use of a charter of acceptable standards in alliance behaviours to guide the conduct of the alliance Participants. This is another way that the value proposition of the no fault - blame proposition could be improved. Any breach by an alliance Participant of the behaviours set out in the charter could be characterised as a 'wilful default'. This would give Non-Owner Participants some comfort that, if the behaviour is not adhered to, there is a mechanism the Owner Participant can use to enforce its bargain.
