The Missouri Veterinary Medical Board filed a lawsuit seeking to enjoin Brooke Gray from filing down sharp enamel points on horses' teeth, which the Board argues constitutes the practice of veterinary medicine. Gray denied the Board's allegations and raised a number of state and federal constitutional affirmative defenses including some based on substantive due process, procedural due process, free speech, and equal protection of the laws. The MVMB filed a Motion for Partial Judgment on the Pleadings in regard to all of the defendants' affirmative defenses, to which the defendants filed a response. After a February 15th hearing on this motion, the Court granted the Board the opportunity to file a Reply to the defendants' response and also allowed the defendants to file this sur-reply.
