If the defendant doesn't show up, and no valid reason is given for his/her absence, the arbitrator will hear the plaintiff's claim and make a decision based on the plaintiff's evidence in the defendant's absence.
Arbitration might be the right choice for some cases. Limited discovery rights and costs might be useful when less is at stake. Arbitration might feel less adversarial, which could be an advantage where ongoing relationships are hoped to be preserved. Arbitration lends some confidentiality.
Some potential consequences may include: Breach of Contract: If arbitration is a contractual requirement and one party refuses to participate, they may be in breach of the contract. The non-complying party may be held liable for damages resulting from the breach.
Section 4 of the Federal Arbitration Act (FAA) says "a party aggrieved by the alleged failure, neglect or refusal of another to arbitrate under a written agreement for arbitration may petition any U.S. district court ... for an order directing that such arbitration proceed in the manner provided for in such agreement."
If neither party appeals the decision, it will be binding, like an order by a judge. However, a party unhappy with the arbitrator's decision can request a new trial before a judge.
Always get straight to the merits without berating the other side or whining about how badly it has treated you. Another threat to your credibility is the “kitchen sink” arbitration demand or a response that includes numerous claims or defenses that have little chance of succeeding.
If one party feels the decision is erroneous, there is very limited opportunity to correct it. There are many cases in which arbitration can become more expensive than court proceedings. Quality arbitrators can demand substantial fees that would not apply in court.

Arguments should flow easily from the relevant facts and applicable law. Avoid exaggerating the strengths of your case as well as disparaging the opposing side. Remember that professionalism and credibility are critical to persuasiveness.
