tion predicated on the Fourth Amendment. DiBella and McLaughlin now appeal.
Chief Wagner and Officer Zupa cross-appeal based on: (1) qualified immunity; and (2) probable cause to issue the summons. They also appeal the jury verdict on the ground that there was insufficient malice to support an award of punitive damages and the punitive damages were excessive.
II. JURISDICTION AND STANDARD OF REVIEW
The District Court had federal question jurisdiction over plaintiffs’ civil rights claim asserted under 42 U.S.C. § 1983. We have jurisdiction of this appeal of the District Court’s final judgment under 28 U.S.C. § 1291, and exercise plenary review over the grant of a Rule 50(b) motion for judgment as a matter of law. Lightning Lube, Inc. v. Witco Corp., 4 F.3d 1153, 1166 (3d Cir.1993) (citing Wittekamp v. Gulf & Western, Inc., 991 F.2d 1137, 1141 (3d Cir.), cert. denied, 510 U.S. 917, 114 S.Ct. 309, 126 L.Ed.2d 256 (1993)).
III. Discussion
Title 42 U.S.C. § 1983 is not a source of substantive rights but a vehicle for vindicating rights conferred by the U.S. Constitution or by federal statute. See Baker v. McCollan, 443 U.S. 137, 145 n. 3, 99 S.Ct. 2689, 61 L.Ed.2d 433 (1979). DiBella and McLaughlin assert a Section 1983 malicious prosecution action for violation of the Fourth Amendment. They contend having to attend their trials for defiant trespass and for violation of N.J.S.A. 2C:33-2a(2) constituted an unreasonable seizure.
To prevail in a Section 1983 action malicious prosecution action, a plaintiff must show:
(1) the defendants initiated a criminal proceeding;
(2) the criminal proceeding ended in the plaintiffs favor;
(3) the proceeding was initiated without probable cause;
(4) the defendants acted maliciously or for a purpose other than bringing the plaintiff to justice; and
(5) the plaintiff suffered a deprivation of liberty consistent with the concept of seizure as a consequence of a legal proceeding.
Estate of Smith v. Marasco, 318 F.3d 497, 521 (3d Cir.2003).
The state initiated criminal proceedings against DiBella and McLaughlin; the criminal proceedings ended in their favor when dismissed on appeal. In the subsequent malicious prosecution trial, the jury found Officer Zupa had no probable cause to issue the defiant trespass summons, and Chief Wagner and Officer Zupa had acted for a purpose other than bringing the plaintiffs to justice. The trial judge vacated the jury verdict by ruling that issuing a summons requiring a criminal defendant to appear in court did not constitute a Fourth Amendment seizure as a matter of law.
Albright v. Oliver, 510 U.S. 266, 114 S.Ct. 807, 127 L.Ed.2d 114 (1994), sets the framework for Section 1983 malicious prosecution jurisprudence. Albright was arrested for the sale of a substance which looked like an illegal drug; he was released after posting bond; and the case was dismissed because the charge did not state an offense under state law. Albright asserted a substantive due process violation but did not claim a Fourth Amendment violation.
The Supreme Court rejected Albright’s Section 1983 malicious prosecution claim based on the Fourteenth Amendment’s Due Process Clause because his surrender to the State “constituted a seizure for the purposes of the Fourth Amendment” id.,
