What is the test for an individual who alleges that they have been denied access to the courts by the courts?

An individual alleging a lack of access to the courts must allege an actual injury. See Lewis, 518 U.S. at 349. "Actual injury" is prejudice with respect to contemplated or existing litigation, such as the inability to meet a filing deadline or present a non-frivolous claim. See id.; see also Phillips v. Hust, 477 F.3d 1070, 1075 (9th Cir. 2007). Delays in providing legal materials or assistance which result in prejudice are "not of constitutional significance" if the delay is reasonably related to legitimate penological purposes. Lewis, 518 U.S. at 362.
