مفهوم کالای معیوب در تحقق خیار عیب در فقه و حقوق بارویکردی بر نظر امام خمینی

One of the methods of prevention of injury or damage to parties to a deal is the practice of option of defection by the person entitled to option. the parties to a deal are entitled to such a right only when the subject of the deal is found to have been defected at the time of contract. but if the concept of defection is not properly defined or if there is no criteria or standard for definition of the concept of defection, then the practice f option of defection becomes difficult. as a result, legislation of the law on compensation of the injury is not practicable. attempts have been made in the present paper to critically study the definitions given by the jurisprudents and refer to their shortcomings in the complicated industrial society today. also in order to delimit the concept of defection, attempts have been made to make a distinction between this concept and other close concepts such as lack of attribute, lack of quality, etc.
