In CSX Transportation v. S.C. Department of Revenue, the Fourth Circuit held that South Carolina failed to justify its exclusion of railroads from a state law that caps the amount that appraisal values on commercial and industrial properties can increase, in a five-year period, at 15%.

In District of Columbia v. Trump, the Fourth Circuit held that the District Court of Maryland did not yet make a final decision on the President’s motion to dismiss Plaintiffs’ individual capacity claims on the grounds of absolute immunity. Therefore, the court held that it does not have jurisdiction to issue an interlocutory order.
