《体育仲裁规则》第R58条规定了体育仲裁院上诉程序的实体法律适用规则。该条款于2013年修订,内容上不同于国际商事仲裁的实体法律适用。首先,它虽然尊重当事人选择的法律规则,但优先适用有关的体育规则;其次,在当事人没有选择的情况下,主要适用作出被上诉决定的体育联合会、体育协会或其他体育组织住所地的国家法,仲裁庭认为适合的法律规则仅仅是补充。此种实体法律适用的差异是由体育行业纠纷的特别性质造成的,应该引起重视。 Section R58 of the PEA Rules sets out the rules applicable to the substantive law of the procedure of appeal in PE courts. This provision was revised in 2013 and is different in content from the substantive law applicable to international commercial arbitration. First of all, while respecting the legal rules chosen by the parties, it gives priority to the relevant sports rules and secondly, it applies mainly to the countries where the sports federations, sports associations or other sports organizations where the appeal is decided have no choice Law, the legal rules that the arbitration tribunal considers appropriate are mere supplements. The differences in the application of such substantive law result from the special nature of disputes in the sport industry and deserve attention.
