  We consider here the stationary Micropolar fluid equations which are a
particular generalization of the usual Navier-Stokes system where the
microrotations of the fluid particles must be taken into account. We thus
obtain two coupled equations: one based mainly in the velocity field u and the
other one based in the microrotation field $\omega$. We will study in this work
some problems related to the existence of weak solutions as well as some
regularity and uniqueness properties. Our main result establish, under some
suitable decay at infinity conditions for the velocity field only, the
uniqueness of the trivial solution.
