In a Riemann–Cartan space‐time U4 the minimally coupled massive spin‐S Dirac equations are subject to constraints for all S> 1/2 . One may seek to modify these equations by the inclusion of appropriate supplementary terms α̂, β̂ (indices suppressed) in such a way that the modified equations are unconstrained. This is done here explicitly in the case where the field spinors are ξν1⋅⋅⋅νn and ημ̇ν1⋅⋅⋅νn−1, with n=2S. The spin‐1 tensor equations, i.e., the minimally coupled Proca equations, are transcribed into spinorial form. The explicit expressions for α̂ and β̂ that so appear are in harmony with those already obtained. The freedom to choose α̂ to be a zero spinor is shown to be circumscribed. Finally, it is pointed out that whether the unconstrained (spin‐1) equations are minimally coupled or not depends on whether one chooses to write them as tensor or spinor equations.
