It has been shown by Starr that net absolute angular momentum cannot be advected by axisymmetric motions alone across a closed surface of constant absolute angular momentum. Hence it has been claimed that certain systems possessing differential rotation about a central axis must be non‐axisymmetric. The theorem is analysed in detail and such a conclusion is shown to be invalid.
