Adjudication can be a frustrating experience, particularly for those who have been faced with a decision of the adjudicator that is quite obviously (to you) wrong, but nonetheless enforceable.
This situation arises because it has long been accepted that, in adjudication, “the need to have the “right” answer has been subordinated to the need to have an answer quickly…” per Chadwick LJ in Carillion v Devonport Royal Dockyard  EWCA 1358.
The Court’s stance on this issue is born from the original intent of the statutory scheme, which was to provide a means for contractors and subcontractors to address cash-flow problems caused by illegitimate delays or refusals to pay. In order to achieve that, adjudication decisions have to bear the weight of authority, otherwise every adjudication decision would immediately be challenged by the losing party.
The Courts also take into account the fact that the adjudicator is tasked with deciding often very complex and detailed disputes in a very short period of time. Errors in decision-making from time to time are therefore inevitable, but the Courts have determined that that shouldn’t be allowed to undermine the process.
