Abuse of court processes

An abuse of process is the unjustified or unreasonable use of legal proceedings or process to further a cause of action by an applicant or plaintiff in an action. It is a claim made by the respondent or defendant that the other party is misusing or perverting regularly issued court process (civil or criminal) not justified by the underlying legal action. In common law it is classified as an 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. Read more: Abuse of process.

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.[1] 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.[2] "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.[3] 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.

The principles which led to a finding of an abuse of process in the UK were stated in Johnson v Gore Wood & Co[4] 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." Read more: Abuse of process.
