Does fabricated evidence violate the Fourth Amendment?

Further, an officer's actions based on fabricated evidence violate the Fourth Amendment only if there is no probable cause without the fabrication. See Franks v. Delaware, 438 U.S. 154, 156 (1978). Thus, where a plaintiff makes a substantial showing that an officer included fabricated evidence in an affidavit, the court should grant summary judgment for a Fourth Amendment claim if the facts nevertheless state probable cause with the fabrication omitted. Hervey v. Estes, 65 F.3d 784, 789 (9th Cir. 1995).
