《联合国国际货物销售合同公约》中的很多条款涉及到了“通知”。考察公约对不同条款的要求是不一样的,有的通知是采取到达原则,有的是采取发信原则。公约根据不同的情况规定发出通知的时间也不同,还规定不同情况下当事人未发通知的法律后果。但是,公约也有不完善的地方。比如,对通知的形式没有作出明确规定,由此产生的问题是合同当事人用行为的方式表示的默示通知是否有效?因为公约没有涉及这样的问题,各个国家的做法也不一样。 Many articles in the UN Convention on Contracts for the International Sale of Goods deal with “notification ”. It is not the same to examine the requirements of the Convention for different clauses, some of them are based on the principle of arrival and some are based on the principle of sending letters. The Convention stipulates the timing of the notification according to different circumstances and also stipulates the legal consequences of the parties’ non-notification under different circumstances. However, the convention also has imperfections. For example, the form of the notification is not clearly defined. The question arises as to whether the implied notification by the parties to the contract is valid. Since the convention does not deal with such issues, the practice of each country is different.
