***Dictionary coverage of 'terminate' and 'with prejudice'*** 

The phrase "with prejudice" is a legal term of long standing. *Black's Law Dictionary*, fourth edition (1968): offers this entry for it:

>**WITH PREJUDICE.** The term, as applied to judgment of dismissal is as conclusive of rights of parties as if action had been prosecuted to final adjudication adverse to the plaintiff. [Case citation:] Fenton v. Thompson, 352 Mo. 199, 176 S.W.2d 456, 460 [1943]. 

A dismissal of a case "with prejudice" means that even though the judge did not permit the case to proceed to full adjudication on its merits, the plaintiff is barred from amending his or her suit to satisfy some shortcoming of the original filing; in effect, the judge has ruled that the suit is incapable of being corrected to the point where it meets a threshold of justiciability. In plain English, "dismissal with prejudice" means "Case dismissed—and don't come back."

*Merriam-Webster's Eleventh Collegiate Dictionary* (2003) offers these definitions of *terminate* as a transitive verb:

>**terminate** ... *vt* **1 a :** to bring to an end : CLOSE {*terminate* a marriage by divorce} {*terminate* a transmission line} **b :** to form the conclusion of {review questions *terminate* each chapter} **c :** to discontinue the employment of {workers *terminated* because of slow business} **2 :** to serve as an ending, limit, or boundary of **3 :** ASSASSINATE, KILL

Definition 1(c) of *terminate* above may be the source of definition 3 (which doesn't appear in the Tenth Collegiate [1993] or any previous edition of the Collegiate Dictionary). In any event the phrase "termination of employment" has a particular legal meaning, according to *Black's Law Dictionary*:

>**TERMINATION OF EMPLOYMENT.** Within policies providing that insurance shall cease immediately upon termination of employment, means a complete severance of relationship of employer and employee. [Citations omitted.]

The fact that *terminate* can mean "assassinate" without the additional wording "with extreme prejudice" suggests that the those last three words are invoking the legal notion that the authorities have already handed down a verdict (in this case, a death sentence) and that no considerations of due process stand in the way of execution of the sentence. I don't mean to argue that such judgments are valid as a matter of law—merely that the wording cloaks the judgment in a legal expression that implies that the decision is binding as a matter of law.

***Early instances of 'terminate with prejudice' and 'terminate with extreme prejudice'***

Instances of the phrase "terminate[d] with prejudice" appear in Google Books search results going back to at least 1941. From [*Institute in Personnel Administration*](https://books.google.com/books?id=5XTRAAAAMAAJ&q=%22terminated+with+prejudice%22&dq=%22terminated+with+prejudice%22&hl=en&sa=X&ved=0ahUKEwjyx9n55fDMAhVSOFIKHVtbBTQQ6AEIPjAH) (1941) [combined snippets]:

>Since many persons who are not eligible for retirement and who must be separated for mental illness are permitted to resign, are terminated for "ill health," or are even **terminated "with prejudice,"** it is impossible to estimate the total number actually leaving the service for this reason.

>An accurate key to the psychopathic personality will be revealed in a scrutiny of the employment and work record of the particular individual. Employment will normally be found to be rather sporadic, with various periods of unemployment, and with various periods of time between jobs. A close look at the individual periods of employment will usually reveal excessive absenteeism for little to no real reason; and termination usually effected either through being fired or otherwise **terminated with prejudice**. 

And from [*Commonwealth ex rel. Montgomery v. Myers*](https://books.google.com/books?id=E0NOAQAAIAAJ&q=%22terminate+with+prejudice%22&dq=%22terminate+with+prejudice%22&hl=en&sa=X&ved=0ahUKEwjR6uLo6_DMAhUIOFIKHRuFBVsQ6AEIIjAB), 422 Pa. 180, 220 A.2d 859 (1966), reprinted in *Pennsylvania State Reports* (1967) [combined snippets]:

>Were the trial judge of the view that the prosecution intentionally sought to infect the proceedings in order to abort the trial, the court's decision to terminate with prejudice to the Commonwealth's right to reprosecute would be entitled to great weight in the event that the issue was presented on review. This, however, is not such a case and the policy of double jeopardy designed to guard against such oppression has no present application. 

Instances in which "terminated with prejudice" appears in court rulings where "with prejudice" has the meaning given in *Black's Law Dictionary* occur in books from [1958](https://books.google.com/books?id=bNwoAQAAMAAJ&q=%22terminated+with+prejudice%22&dq=%22terminated+with+prejudice%22&hl=en&sa=X&ved=0ahUKEwiUw9fj9_DMAhUJeFIKHd8kAwIQ6AEIKzAD) and [1960](https://books.google.com/books?id=Q661AAAAIAAJ&q=%22terminated+with+prejudice%22&dq=%22terminated+with+prejudice%22&hl=en&sa=X&ved=0ahUKEwiUw9fj9_DMAhUJeFIKHd8kAwIQ6AEIODAG).

The phrase "terminate with extreme prejudice" begins to appear as euphemisms for *assassinate* in 1969. In some of the earliest instances, the phrase arises in connection with assassination of double agents—that is, agents who were in some sense employees of the U.S. government or its branches (typically the CIA). From [*Newsweek*](https://books.google.com/books?id=plgTAQAAMAAJ&q=%22terminated+with+extreme+prejudice%22&dq=%22terminated+with+extreme+prejudice%22&hl=en&sa=X&ved=0ahUKEwjEuLK88vDMAhUCfVIKHdomDIMQ6AEIOjAG), volume 74 (1969):

>Over the next few days, the [Green] Berets contacted the CIA and asked for advice in dealing with Chuyen. According to the Berets' story, the CIA mission chief in Saigon refused to take a hand in the matter and the CIA strongly implied that Chuyen would have to be murdered—"**terminated with extreme prejudice**" was the alleged phrase. Thus on June 20, according to the U.S. Army specifications against the Berets, the suspected double agent was bundled into a 30-foot-long boat, drugged with morphine, shot in the head and dumped in a weighted sack into a shark-infested area of the South China Sea. The CIA steadfastly denies that any of it agents knew of the Berets' intention to commit the murder and claims that it had advised the Berets not to kill Chuyen.

From [*December*](https://books.google.com/books?id=RsxPAAAAYAAJ&q=%22termination+with+extreme+prejudice%22&dq=%22termination+with+extreme+prejudice%22&hl=en&sa=X&ved=0ahUKEwiJjJ3-8PDMAhVNRFIKHT_1D6gQ6AEIIjAB), volumes 12–15 (1970[?]):

>During the Green Beret murder affair, the phrase "**termination with extreme prejudice**" had figured prominently in statements by a defense lawyer who claimed it was accepted military jargon for authorizing the murder of believed double agents.

From [*Congressional Record*](https://books.google.com/books?id=Gbs90iR0etYC&q=%22terminate+with+extreme+prejudice%22&dq=%22terminate+with+extreme+prejudice%22&hl=en&sa=X&ved=0ahUKEwij46rG9PDMAhUPE1IKHSXXDTcQ6AEIHTAA) (1971):

>MODERATOR: Does the term exterminate, to **terminate with extreme prejudice**—are you familiar with that term? 

>OSBORN. There are two ways—yes—there are two ways to terminate an agent. When you are through with the agent, that is, when he serves no more function to you, you can do one of two things. You can terminate him by paying him an amount of money, thanking him for his service, swearing him to secrecy, and simply letting him go—that's without prejudice. There is **termination with prejudice** where the agent constitutes a threat either to your operations, to you personally as a case officer, to whatever has determined the threat, and you **terminate him with prejudice** by either killing the individual or perhaps relocating him in the—I remember one incident of an agent up in Phuo By who was relocated as a prisoner of war into a Chieu Hoy camp and reoriented—I'm not really familiar with the details of that, but the main idea was to, of course, neutralize the individual. I got orders a couple of times to **terminate agents with prejudice** because of things they had done which were considered illegal or in bad taste or threatening—bad security—while I was there [in Vietnam].

Not long after the term became known, however, it appears to have become a euphemism for arbitrary execution without even a decision higher in the chain of command to justify it. From [*Far Eastern Economic Review*](https://books.google.com/books?id=jFtOAQAAIAAJ&q=%22terminate+with+extreme+prejudice%22&dq=%22terminate+with+extreme+prejudice%22&hl=en&sa=X&ved=0ahUKEwiZzbz3-PDMAhUNRVIKHShXCHE4ChDoAQgoMAM) (1969) [combined snippets]:

>His only defence was to play the part to the hilt, and one of his more endearing habits was to point a pistollike finger at anyone who incited his disapproval and to say loudly: “TWEP!” He explained drily: “Terminate With Extreme Prejudice."

An item in [*Verbatim*](https://books.google.com/books?id=DEdBAQAAIAAJ&q=%22terminate+with+extreme+prejudice%22&dq=%22terminate+with+extreme+prejudice%22&hl=en&sa=X&ved=0ahUKEwia0ebF-fDMAhUREVIKHWnBAx4Q6AEIHTAA), volume 8 (1982) [combined snippets] gives what I take to be the CIA side of the story:

>***terminate with extreme prejudice.*** This is now firmly planted in the public ethos as intelligence jargon for 'to murder,' again thanks to *Time*. I have terminated at least four agents with extreme prejudice myself, without ever infringing on the Sixth Commandment. To *terminate* simply means to 'sever contact' with an agent on friendly terms, usually because he is no longer needed or because he has lost his access to the target for which he was recruited. He is usually given contact instructions in case he ever needs to get in touch again, and his file is retired to Registry.

>*To **terminate with prejudice*** means that a not will be put in his file strongly recommending that no further contact be initiated (nor will he be given the means to establish it). He has been a handling headache, whether insecure, inaccurate (or worse) in his reporting, unreliable, cheating on his expense account, or found to be engaged in criminal activities on the side. 

>*To **terminate with extreme prejudice***, a *bum notice* is circulated to friendly liaison intelligence services, informing them that while he did indeed work for us, his conduct was so bad—outright fabrication of information or an attempt to perpetrate a major fraud—that we are warning them to have nothing to do with him if he appears on their doorstep, as he probably will.

Why the agency found it necessary to separate instances of "terminate with prejudice" (don't initiate contact because the guy is either corrupt or utterly unreliable) from instances of "terminate with extreme prejudice" (don't allow the guy to initiate contact with you because he is either corrupt or utterly unreliable) is not entirely clear from the unnamed gentleman's explanation. Nor does it indicate what term the agency would have used to indicate "assassinate this guy because we have determined that he's a dangerous double agent."

***Conclusions***

The expression "terminate with extreme prejudice" seems to have arisen during the Vietnam War as an instruction to assassinate an agent or other contact in the field. The idea underlying this euphemism may have come from *termination* in the sense of ending a person's employment, since the agents in question were working as spies or informers for the CIA or military intelligence. 

But the word also invokes the legal notion of "with prejudice"—meaning that though a full-fledged adjudication has not run to completion, the legal force of the judge's dismissal of the suit is final, and the insufficient or otherwise faulty plea of the plaintiff is not amendable to make it acceptable to the court. In terms of an assassination order, "terminate" would seem to mean "kill," and "with extreme prejudice" would seem to imply "with no right of appeal from this order."
