Abuse of process

Abuse of process is a common law intentional tort. It is to be distinguished from malicious prosecution, another type of tort that involves misuse of the public right of access to the courts.

The elements of a valid cause of action for abuse of process in most common law jurisdictions are as follows: (1) the existence of an ulterior purpose or motive underlying the use of process, and (2) some act in the use of the legal process not proper in the regular prosecution of the proceedings. Abuse of process can be distinguished from malicious prosecution, in that abuse of process typically does not require proof of malice, lack of probable cause in procuring issuance of the process, or a termination favorable to the plaintiff, all of which are essential to a claim of malicious prosecution. "Process," as used in this context, includes not only the "service of process," i.e. an official summons or other notice issued from a court, but means any method used to acquire jurisdiction over a person or specific property that is issued under the official seal of a court. Typically, the person who abuses process is interested only in accomplishing some improper purpose that is collateral to the proper object of the process and that offends justice, such as an unjustified arrest or an unfounded criminal prosecution. Subpoenas to testify, attachments of property, executions on property, garnishments, and other provisional remedies are among the types of "process" considered to be capable of abuse.

Principle
The principles which lead to a finding of an abuse of process in the UK were stated in Johnson v. Gore Wood & Co by Lord Bingham.

“The underlying public interest is … that there should be finality in litigation and that a party should not be twice vexed in the same matter. This public interest is reinforced by the current emphasis on efficiency and economy in the conduct of litigation, in the interests of the parties and the public as a whole. The bringing of a claim or the raising of a defence in later proceedings may, without more, amount to abuse if the court is satisfied (the onus being on the party alleging abuse) that the claim or defence should have been raised in the earlier proceedings if it was to be raised at all. I would not accept that it is necessary, before abuse may be found, to identify any additional element such as a collateral attack on a previous decision or some dishonesty, but where those elements are present the later proceedings will be much more obviously abusive, and there will rarely be a finding of abuse unless the later proceeding involves what the court regards as unjust harassment of a party. It is, however, wrong to hold that because a matter could have been raised in earlier proceedings it should have been, so as to render the raising of it in later proceedings necessarily abusive. That is to adopt too dogmatic an approach to what should in my opinion be a broad, merits-based judgment which takes account of the public and private interests involved and also takes account of all the facts of the case, focusing attention on the crucial question whether, in all the circumstances, a party is misusing or abusing the process of the court by seeking to raise before it the issue which could have been raised before. As one cannot comprehensively list all possible forms of abuse, so one cannot formulate any hard and fast rule to determine whether, on given facts, abuse is to be found or not … Properly applied, and whatever the legitimacy of its descent, the rule has in my view a valuable part to play in protecting the interests of justice.”

Distinguished from Malicious Prosecution
A cause of action for abuse of process is similar to the action for malicious prosecution in that both actions are based on and involve the improper use of the courts and legal systems. The primary difference between the two legal actions is that malicious prosecution concerns the malicious or wrongful commencement of an action, while, on the other hand, abuse of process concerns the improper use of the legal process after process has already been issued and a suit has commenced. While technically, the service of process itself--in the form of a summons--could be considered abuse of process under the right circumstances, e.g. fraudulent or malicious manipulation of the process itself. In malicious prosecution, the wrongful act is the actual filing of the law suit for improper and malicious reasons, whereas in abuse of the process, the legal process is misused for some purpose which is considered improper under the law. As noted above, the three requirements of malice, lack of probable cause in the issuance of the process, and a termination of the prior proceeding favorable to the plaintiff, are essential elements for malicious prosecution. Most jurisdictions to not require any of these three elements in order to make out a prima facie case for abuse of process.

Illustration
A cause of action for abuse of process may lie in situations where a criminal proceeding is brought against a defendant for improper motives. For example, in Lader v. Benkowitz,, a pleading was held to state a good cause of action for abuse of process when it alleged that defendant hotel owner had threatened to have the plaintiff arrested on a warrant issued at the behest of the defendant on a charge of disorderly conduct. The allegedly improper motive was the hotel owner's underlying purpose of compelling plaintiff to pay a bill owed for plaintiff's alleged rental of a room in defendant's hotel. It was claimed that through the unlawful use of the warrant and threat of arrest, the defendant was able to obtain the sum of money allegedly owed by plaintiff. In denying defendant's motion to dismiss, the court admonished that it was sufficient to show that regularly issued process had been used to accomplishment an improper purpose in order to set forth a cause of action for abuse of process. The fact that the plaintiff had yielded to defendant's threat to have her arrested under the warrant did not diminish the cause of action, because it was clear that the plaintiff actually been arrested for the purpose of compelling her to pay the cost of the room.
