Arbitration has long been viewed as a faster, more efficient alternative to litigation. But anyone involved in construction disputes today knows that is not always the case. The process can be just as costly, sometimes taking as long as a court case. Yet one thing remains consistent, and it is the most important point for everyone in the construction process to understand before signing an arbitration clause: once an arbitrator decides, that decision is almost always final.

That reality was reinforced in a recent Tennessee Court of Appeals decision, MidSouth Construction, LLC v. Burstiner (June 12, 2025) (pdf). The case involved a homeowner who tried to overturn an arbitration award following a dispute about defective deck construction. The homeowner argued that the arbitrator’s decision was “fundamentally irrational.” The court rejected that argument.
