    "abstract": "We study the effects of a barely perceivable violation of Lorentz invariance\non results computed using a relativistic constituent quark model wave function.\nThe model nucleon wave function of Gross {\\it et al.} is constructed such\nthatthere is no orbital angular momentum and that the spin-dependent density is\nspherical. This model wave function is claimed to be manifestly covariant, but\nwe show that this is not so. In particular,the seeming covariance of the matrix\nelements of the electromagnetic current arises from using the Breit frame.\nMatrix elements have a different appearance in any other frame.",
