按仲裁法第17條第1項規定，當事人請求仲裁人迴避者，應於知悉迴避原因後十四日內，以書面敘明理由，向仲裁庭提出。但當事人另有約定者，不在此限。該項但書有避免外界所詬病、由仲裁庭自為決定仲裁人迴避的功用。本會仲裁院已將仲裁人迴避事件之審議納為重要職掌事項，以供當事人就迴避事件合意交其決定。惟若無該約定，該院因缺乏權源，迴避事件依法仍應由仲裁庭決定。請詳參本會官網仲裁院迴避決定資料庫（112仲聲迴字第001號決議）。
According to Article 17 paragraph 1 of Taiwan's Arbitration Law, a party intending to request for the withdrawal of an arbitrator shall, within fourteen days after knowing the cause for withdrawal, submit a written application stating the reasons for withdrawal to the arbitral tribunal, “unless the parties have agreed otherwise”. This proviso prevents the arbitral tribunal from deciding arbitrator challenge on its own initiative. One of the most important functions of the CAA Court of Arbitration (CAA Court) is to decide on challenges to arbitrators. However, in the absence of the parties' agreement, the CAA Court does not have the power to make such decisions, as the arbitral tribunal would be the decision-maker pursuant to Article 17 paragraph 1: see Decision 112 Zhong-sheng-hui 001 (Database of Decisions on Challenges of Arbitrators).
