Defence

Both are essentially the same. When right of self defense is codified into legislative enactment as legal right from Sections 96 to 106 of I.P.C., it has been given the name Right of Private Defense. May read judgment of Supreme Court in Darshan Singh vs State Of Punjab & Anr on 15 January, 2010, Appeal (crl.) 1057 of 2002,, Supreme Court has explained the right of private defense and it's restrictions very clearly.

In Vidhya Singh v. State of Madhya Pradesh (1971) 3 SCC 244, Supreme Court observed that "the right of self-defence is a very valuable right, serving a social purpose and should not be construed narrowly."

It clearly means -

1. Right of self defense is a very valuable right

2. Right of self defense serves a social purpose

3. Right of self defense should not be construed narrowly
