In case of a rotational motion (Rigid body Dynamics), we can always apply Newtan's laws of motion about an axis passing through the Center of Mass of body. Why? Why can't we always apply Newtans' laws of motion about an axis about which the rigid body happens to be in pure rotation?

For a body in rotation the center of mass is the only point which remains in transient motion, rest others are in rotation.

For translation motion net force about centre of mass should be non zero. If a body has non zero net force along any direction passing through c.m will experience acceleration.

it is because the whole mass of the body is supposed to be concentrated at the centre of mass and the force at the centre of mass cause an acceleration of the rigid body.so we need to apply the newton's law about an axis passing through centre of mass. if we apply newton's law about an axis...

1) newtons laws of motion are valid only in inertial frame of reference,i.e, a frame in which there is zero acceleration(though velocity may have non-zero but constant value) . 2) the whole mass of the body can be assumed to be at its centre of mass and the object can then be treated as a point object...
