Hoisting canadian flag on house of nri when he come to india

Sir,

Can Canadian immigrant (NRI) hoist Canadian flag on his house when visiting his home in India . If so any permission required or not .

Depends on where he is living. Is state Govt run by BJP or Congress, what is major political influence in city etc. Rules written in law books are irrelevant in these type of matters. In India these type of matters are usually decided by mobs and rules of jungle rather than in premises of a court.

Please state facts of the case

Sir,

One NRI now lives in India.For the heck of it he hoists Canadian flag on 6-7 pole that too not fixed properly. Will such action be objectionable? Is it illegal to hoist foreign Nations flag in india on your house tops. If it is illegal we want to advise him accordingly.
