laches
laches n. 迟误 指当事人在主张或实现其权利方面的疏忽、懈怠或有不合理的拖延。迟误是衡平法上的一项制度，即如果原告疏于主张其权利或者有不合理的拖延，而其疏忽和拖延已经损害了对方当事人的利益，则衡平法院可以拒绝原告提出的救济请求。迟误制度的根据是「衡平法佐助警醒者，而不佐助怠惰者」〔equity aids the vigilant and not the indolent〕这一衡平法原则。所以，与普通法上的时效制度类似，如果一项衡平法上的权利像普通法上的权利那样，在通过起诉来实现该权利时受一定时效期间的限制，则衡平法院可以将普通法上关于时效的规定同样适用于该项衡平法上的权利。

Law French
Law French 法律法语 指自12世纪60年代到爱德华三世〔Edward Ⅲ，1327-1377〕统治时期用于法律文书和诉讼程序中的盎格鲁-诺曼语〔Anglo-Norman〕。这种法语直到18世纪早期还在法律文书中被经常使用。根据议会立法，于1733年最终废止。当最初引入英格兰时，这一类法语是在诺曼底〔Normandy〕使用的标准语言。到了14世纪，经过一种语言的隔离，它又变成了一种充斥着讹误的语言，当然这是以纯正的法语为比较对像而言的。在判例汇编中运用法律法语的现象一直持续到了17世纪末，晚至18世纪早期甚至还有人为法律法语而辩护。这些人认为：「实际上法律很难用英语来确切地表达。」尽管法律法语对讲英语的律师来说可能有一些艰深晦涩，但它确实在法律语言中留下了许多专业用语，如appeal, attainder, assault, arrest, counsel, defer, escheat, heir, indictment, joinder, laches, mortgage, nuisance, ouster, process, reverter, suit, tort, verdict等。法律法语通常是一门高度专门性的术语，并保留了许多古老的盎格鲁-诺曼语的特点，但最终仍被英语的语言形式、曲折变化、词序、词的配列等替代。因此，尽管英语中保留了许多法律法语的词汇，今天的英美法律师已不再试图以法律法语来交流了。
