Hello sujnyanendra, you are correct that a computer printout can be presented as evidence. However, you need to understand the context in which the computer printout can be taken as evidence. Only in the cases where the source is computer itself and not something where the computer was merely acting as a display unit for XYZ website.
Please understand the “spirit” and don’t be fooled by the words of the electronic evidence. Imagine you write a book, now you want that whatever you mention in that paperback should be taken as evidence in the court of law for anything mentioned in it. My question to you, will such a book be taken as evidence for all the data that’s published in it?
Another way to look at this is, do you know of any personal website which has evidentiary value for all the documents it has published quoting data or information from other sources? You may say Wikipedia, but try quoting Wikipedia in a court, it will not be taken as evidence because its managed by wiki authors and they rely on primary sources like published research papers as well as newpapers, which cannot be used as evidence. I am a wiki editor, so I know what I am talking about here J
I hope you have got answer by now.
