  In a recent paper[1], it has been shown that, there cannot be any rotating
(Kerr) Black Hole (BH) with finite mass in order that the generic properties
associated with the symmetries of stationary axisymmetric Einstein equations
are obeyed, i.e, in order to have m\ge 0, we must have $a=0$. In other words,
all observed chargeless BHs with finite masses must be non-rotating
Schwarzschild BHs. Here, by comparing the invariant 4 volume associated with
original Kerr metric [2] with the Boyer-Lindquist version of the same [3], we
further find that, stationary axisymmetric {\em vacuum} Einstein solutions
actually correspond to m=0 in addition to a=0! This means that if the Kerr
solution is a unique one, the Schwarzschild BHs too correspond to only m=0 and
therefore the observed BH candidates (BHs) with m >0 are not BHs at all. This
is in agreement some detailed analysis of recent observations[4-7] which
suggest the the BHCs have strong intrinsic magnetic moment rather than any
Event Horizon. If one would derive the Boyer-Lindquist metric in a
straightforward manner by using the Backlund transformation, it would follow
that a= m sin phi, where phi is the azimuth angle. This relationship directly
confirms the result that for a supposed rotating BH, actually, both a=m=0.
