Hey just saw your reply after posting my earlier reply. I do not think what you qouted about constitution law is in the constitution of India (Bare Act). It might be a qoute in a judgment or by someone. I might be able to research on a judgment about this qoute. Let me know if you need help.
Agreed.
Any judgement passed by any High Court or The Supreme court where that quote is directly mentioned then you can use that case and quote as a referring point of argument, but that should be done in court during a trial if such a situation arises. Digging up documents based on just a quote can turn out to be costly (in my experience).
