  Contrary to the usual belief, by carefully examining the operation of parity
transformation on the $(1,0)\oplus(0,1)$ mesons in the generalized canonical
representation, we establish that the $(j,0)\oplus(0,j)$ meson-antimeson pair
have {\it opposite} intrinsic parity. This opens up the possibility that while
the particles without an internal structure may utilize one representation of
the Lorentz group, phenomenologies of composite particles may exploit a
different representation. As such (perhaps, only some of) the meson structures
beyond the standard $q\,\overline {Q}$ may exploit the $(j,0)\oplus(0,j)$
generalized canonical representation of the Lorentz group -- this would result
in a meson and the associated antimeson to manifest themselves in {\it
different} partial waves.
