Explanation:

Section 11 of the Indian Evidence Act deals with the plea of alibi. Which says that evidence can be given of facts which have no other connection with the main facts of a case except this that they are inconsistent with .a fact in issue or a relevant fact. Their inconsistency with the main facts of the case is sufficient to warrant their relevancy. Thus this section enables a person charged with a crime to take what is commonly known as the plea of alibi, which means the presence elsewhere at the time of crime. This plea establishes the impossibility of crime and the presence of the accused at the scene of the offence.
