1 U.S. perjury law
At common law, perjury has been described as âthe willful giving, under oath, in a judicial proceeding or course of justice, of false testimony material to the issue or the point of inquiryâ (J. Bishop, 2 Commentaries on the Criminal Law § 860, 1858). The âcourse of justiceâ refers to a proceeding, such as a creditorâs examination of a debtor or during a grand jury inquiry.
Other general understandings of perjury are specified in state and federal statutes and in the Courtâs explanations of previous cases. The federal statutory definition in 18 United States Code Section §1621 declares:
Whoever â having taken an oath before a competent tribunal, officer, or person, in any case in which a law of the United States authorizes an oath to be administered, that he will testify, declare, depose, or certify truly, or that any written testimony, declaration, deposition, or certificate by him subscribed, is true, willfully and contrary to such oath states or subscribes any material matter which he does not believe to be true; or in any declaration, certificate, verification, or statement under penalty of perjury as permitted under section 1746 of title 28, United States Code, willfully subscribes as true any material matter which he does not believe to be true: is guilty of perjury and shall, except as otherwise expressly provided by law, be fined under this title or imprisoned not more than five years, or both. This section is applicable whether the statement or subscription is made within or without the United States.
Linguists will notice that Section §1621 says, âdoes not believe to be trueâ rather than âknows not to be trueâ or âknows to be false.â To believe something is true or false is not the same as to know it is true or false, a semantic distinction that was apparently not conveyed in this US statute. Searle (1979, 12) observes that belief is a determinable rather than a determinate and asks, âWhen does the report of a manâs belief entail that the belief is true?â (159). Green (1989, 3) writes, âbelief is what makes the difference (obviously) between a lie and a mistake. When people say something false that they believe to be false, they are lying, but if they say something that is false but they happen to believe it to be true, they are merely mistaken.â The United Kingdomâs Perjury Act of 1911 includes both of the words, âknow,â and âbelieve,â in its definition of perjury: âIf any person lawfully sworn as a witness or as an interpreter in a judicial proceeding willfully makes a statement material in that proceeding, which he knows to be false or does not believe to be true, he shall be guilty of perjury âŚâ
It seems that both the US and UK perjury statutes permit peopleâs belief that something is true or false as sufficient to protect them from being charged with perjury. The question is how we can determine their intentions. If concrete evidence of this can be found in other communications by the witness, this evidence can be used to support their intended meanings. Lacking such evidence, Nunberg (1978, 94â97) suggests two context conditions that aid interpretation: (1) when a communityâs normal belief about the meaning of that word is consistently used, and (2) when that word refers to things that are not normally represented by it. It would appear that legal communities in both the US and UK rely on statutes that consistently and normally state that when witnesses state that they believe something is either true or false such statements are at least somewhat equivalent to knowing that thet are either true or false. This also is consistent with Blackâs Law Dictionaryâs definition of believe as 1. âto feel certain about the truth of; to accept as true; 2. to think or suppose,â and knowing is â1. having or showing awareness or understanding: well informed. 2. deliberate; conscious.â
1.1 False statements about material matters under oath
Under §1621(1), the following is required to prove that persons have committed perjury: a speaker under oath before a judicial proceeding makes an oral statement relating to a material matter that the speaker knows to be false.
Perjury is not just any misstatement made while under oath. The Supreme Court of the United States has explained:
A witness testifying under oath or affirmation violates this section if she gives false testimony concerning a material matter with the willful intent to provide false testimony, rather than the result of confusion, mistake, or faulty memory.
(United States v. Dunnigan, 507 U.S. 87, 94 (1993))
Here a âmaterial matterâ refers to false statements that have the potential of influencing the outcome of a trial or other official proceedings. But some false statements are not material to trial outcomes. False statements are different from simply making a mistake, because the law requires that any perjurious statements be made intentionally. These are considered different from evasion or half-truth because the perjury must be about some matter that the witness believes to be false and while doing so creates a misleading impression through indirection. While this may be dishonest, the law does not always consider this perjury.
1.2 Possible errors
The possibilities of errors in judging whether or not perjury has taken place appear in several contexts that are not relevant to the application of linguistic analysis. For example, there is a requirement that the witness be under oath. On rare occasions there have been times in which a witness testified without first being sworn. Another type of error happens when the person giving the oath is not qualified to do so. This arises more frequently in out-of-court proceedings, as in depositions and in those âcourses of justiceâ referred to in the common law definitions of perjury. Obviously, these are issues for attorneys to address rather than linguists.
1.3 Perjury vs. false statements
There is a difference between perjury and false statements, because perjury connotes corruption and recalcitrance, while false swearing, usually made in a written statement while not under oath, connotes mere falsehood without moral judgment (Garner 1995). This difference is recognized in some jurisdictions but not in others.
In the U.S. federal jurisdictions, some false statements given while not under oath can be as damning as perjury (18 U.S.C. § 1001). In fact, if persons falsely deny that they committed a crime during their interviews with federal officers and give an exculpatory ânoâ or a mere âI didnât do it,â they can be imprisoned for five years and be fined $10,000 (Brogan v. United States, 552 U.S. 398, 1998). For example, this was the 2004 stock trading crime for which the famous television personality, Martha Stewart, was convicted.
1.4 Linguistics and perjury
Linguistic analysis fits into this picture because the determination of perjury rests on the language used by both the questioner and the person who responds, which language in turn has to be assessed by the jury or by the judge in bench trials. Their task is how to determine whether perjury actually took place, whether it was mi...
