The article examines the need to give reasons in an Award and when a challenge under Arbitration Act 1996 (AA 1996) s 68 can be made in the event that there is a failure to give reasons. A reasoned award is one that allows the reader to understand how the tribunal arrived at its conclusion. It should set out what happened, having regard to the evidence, and should explain succinctly why, in the light of what happened, the tribunal reached its decision and what that decision is. A failure by an arbitrator to provide a reason or sufficient reasons for its award may make the award susceptible to challenge. However, a failure to consider evidence or an award which is manifestly wrong or irrational may not be open to challenge under AA 1996 s 68.
