What is a plaintiff's due process right to pursue a civil action without active interference?

Amendment due process right to pursue legal redress by filing civil actions that have a reasonable basis in law or fact. See Silva, 658 F.3d at 1102. To state a claim for a violation of the right to litigate without active interference, the plaintiff must allege that he has suffered an actual injury, such as the dismissal of his pending action. See id. at 1103-04. Additionally, the "underlying cause of action, whether anticipated or lost, is an element that must be described in the complaint, just as much as allegations must describe the official acts frustrating the litigation." Christopher v. Harbury, 536 U.S. 403, 415 (2002).
