限购令效力困惑与破解:溯及力与不可抗力的适用

Puzzle and Solutions on the Effectiveness of Purchase Limit Order: the Application of Retroactivity and Majeure

限购令不具有溯及力,限购令会因合同对外缺乏公示性被轻易规避,导致限购令形同虚设,不仅房价继续非理性上涨,而且使限购令保护公共利益的目的落空。反之,限购具有溯及力,购房合同当事人基于当时授益性的法律规定,依法享有的合同信赖利益无法实现。为了兼顾公共利益和个人利益合理保护,限购令对其生效前不具有公示性的合同具有溯及力,但限购令溯及既往并非导致合同无效,而是构成合同履行障碍。购房合同履行障碍的破解途径:合同或协议解除,或部分履行,或以后继续履行。

If the purchase limit order is not retroactive, it will result in the purchase limit order exists in name only due to lack of external publicity and was easily circumvented. Conversely, if the purchase limit has a retroactive effect, the law will not achieve alliance with the public interest. In order to balance reasonable protection between public interests and personal interests, the purchase limit order will have retroactive effect before its entry into force, but the retroactive lead to the contract performance obstacles instead of invalidity of the contract. The way of solution to overcome obstacles is to lift contract or agree- ment, or to do partial performance, or to perform later.
