《合同法》中对于无效合同是否受诉讼时效限制没有作出相应规定,从而造成理论派和务实派之间对此争论不休,在司法实践过程中适用的标准也不一致。结合最近最高人民法院《关于无效合同所涉诉讼时效问题的规定》(征求意见稿),本文拟论述确认合同无效请求权是否受诉讼时效的限制,并进一步探讨合同无效后的财产返还请求权是否受诉讼时效限制,及若适用诉讼时效如何确认起算点的问题,通过该文笔者意在对无效合同的处理起到抛砖引玉的作用。 There is no corresponding stipulation in the Contract Law whether the invalid contract is limited by the limitation of action, which leads to the endless debate between the theoretical school and the pragmatic school and the inconsistent standards in the judicial practice. Combined with the recent Supreme People's Court, “Provisions on the Limitation of Litigation over Invalid Contract” (Draft for Comment), this article discusses whether to confirm the contract invalid claims are subject to limitation of action, and to further explore whether the right to return the contract after the property claims are Subject to the limitations of the limitation of action and how to confirm the starting point if the applicable limitation of action expired. Through this article, the author intends to play a valuable role in the handling of the invalid contract.
