The case is made on the example of $(3/2,0)\\oplus(0,3/2)$, for the sake of concreteness and without loss of generality. Namely, we use as a vehicle for the aforementioned covariant single spin-$3/2$ description the antisymmetric tensor of second rank with Dirac spinor components, $\\Psi_{[\\mu\\nu]}=B_{[\\mu\\nu]}\\otimes\\psi$. The $(3/2,0)\\oplus(0,3/2)$ sector of interest is tracked down in two steps.
