Civil Rights — 42 U.S.C. Sec. 1983 Claim— - Fourth Amendment Claim — Malicious Prosecution is a claim made against a government official, such as a police officer, prosecutor, or judge, for violating a person's civil rights. Specifically, it alleges that the government official maliciously and without probable cause initiated and continued a criminal prosecution against the plaintiff. There are two types of malicious prosecution claims: a Fourth Amendment claim and a 42 U.S.C. § 1983 claim. A Fourth Amendment claim alleges that the individual's right to be free from unreasonable searches and seizures was violated when the government official initiated the criminal prosecution. The plaintiff must prove that the criminal proceedings were initiated without probable cause and that the action was motivated by malice or improper purpose. A 42 U.S.C. § 1983 claim alleges that the government official was acting under the color of law and deprived the plaintiff of his or her civil rights. The plaintiff must prove that the defendant deprived the plaintiff of a Constitutional right, such as the right to be free from unreasonable searches and seizures, without due process of law. The plaintiff must also prove that the defendant acted with the specific intent to violate the plaintiff's civil rights.
