1. The institution of a criminal or civil proceeding for an improper purpose and without probable cause. * The tort requires proof of four elements:
(1) the initiation or continuation of a lawsuit;

(3) malice; and
(4) favorable termination of the original lawsuit. Restatement (Second) of Torts §§ 674-81B (1977).
2. The tort claim resulting from the institution of such a proceeding. * Once a wrongful prosecution has ended in the defendant’s favor, he or she may sue for tort damages. — aka (in the context of civil proceedings) malicious use of process; (archaically) malicious institution of civil proceedings.

1. A criminal prosecution or civil suit commenced maliciously and without probable cause. After the termination of such a prosecution or suit in the defendant’s favor, the defendant has the right to bring an action against the original plaintiff for the tort of “malicious prosecution.” 
Excerpt from Martin L. Newell’s A Treatise on the Law of Malicious Prosecution, False Imprisonment, and the Abuse of Legal Process (1892):
“Malicious prosecution — The action of, defined. — A judicial proceeding, instituted by one person against another from wrongful or improper motives, and without probable cause to sustain it. It is usually called a malicious prosecution; and an action for damages for being subjected to such a suit is called an action for malicious prosecution. In strictness, the prosecution might be malicious, that is, brought from unlawful motives, although founded on good cause. But it is well established that unless want of probable cause and malice concur no damages are recoverable. However blameworthy was the prosecutor’s motives, he cannot be cast in damages if there was probable cause for the complaint he made. Hence, the term usually imparts a causeless as well as an ill-intended prosecution. It commonly, but not necessarily, means a prosecution on some charge of crime.“ 
Excerpt from J.F. Lever’s “Means, Motives and interests in the Law of Torts,” in Oxford Essays in Jurisprudence (A.G. Guest ed., 1961):
“The mental element which is requisite to found liability for malicious prosecution is similar to that which is sufficient to destroy qualified privilege in libel: it amounts to an abuse of the right to prosecute which is based on the public interest in bringing criminals to book. The abuse here arises from the fact that the prosecution is animated by a desire to use the criminal law for some purpose for which it is not intended. It is particularly unfortunate that the word ‘malice’ was ever used in this context for it is quite possible for a prosecutor to have been inspired by personal dislike of the plaintiff and by a desire for vengeance against him and yet not be liable for malicious prosecution; and this may happen even where the proceedings were instituted without reasonable and probable cause, if the prosecutor honestly believed that he had a good case and that he could therefore satisfy his animosity against the plaintiff by obtaining his conviction.“ 
Excerpt from 52 Am. Jur. 2d Malicious Prosecution § 2, at 187 (1970):
“The distinction between an action for malicious prosecution and an action for abuse of process is that a malicious prosecution consists in maliciously causing process to be issued, whereas an abuse of process is the employment of legal process for some purpose other than that which it was intended by the law to effect the improper use oi a regularly issued process. For instance, the initiation of vexatious civil proceedings known to be groundless is not abuse of process, but is governed by substantially the same rules as the malicious prosecution of criminal proceedings.“ 
malicious use of process – In essence a form of malicious prosecution. The use of civil process without probable cause. Nix v Goodhil, 95 Iowa 282, 63 NW 701. 
1. The use of process for a purpose for which it was intended, but out of personal malice or some other unjustifiable motive (EXAMPLE: to extort money) and without probable cause. it is, in effect, a form of malicious prosecution.
