摘要： 不受判决拘束的案外人的权益可能受判决损害，另诉未必能使其获得救济。美国也有第三人撤销之诉，德国的部分案外人异议之诉实为第三人撤销之诉。美、德、法的不受判决拘束者均可提起撤销之诉。由于案外人是初次就系争事项进行诉讼，难以适用我国的再审程序，故案外人的救济途径应为第三人撤销之诉。对判决的撤销，原则上应是相对撤销(原判决对其当事人仍有效)，但当下只能采绝对撤销。应当扩大第三人撤销诉讼的适用主体和适用范围，放宽损害要件，且设置一般债权人起诉的特别要件，废弃预决效力的规定。

Abstract: Nonparty’s not bounding by a judgment doesn’t mean he may not be adversely affected by it. Institutingan ordinarily action can not necessarily give remedy to him. USA and Germany have nonparty’s revocation litigation too，and persons not bound by judgment can also lodge this kind of litigation. Nonparty has not litigated on the cause of action，making retrial procedure very difficult to use，so nonparty’s remedy should be revocation litigation. Revocation should be relative in principle，but we have to adopt absolute revocation atpresent. The existing nonparty’s revocation litigation can widely apply to the third party. Legislation institutionand the Supreme Court should both devote to perfecting the current law. We should extend the range of application of revocation litigation，permit nonparty lodging suit as soon as suffering danger, abolish evidence requirement of filing litigation，cancel nonparty’s motion for new trial，set up additional requirement for ordinary creditor, discard pre-determined effectiveness of judgment.
