how to prove perjury? How is perjury proved in a rental arbitration hearing? The testimony is sworn. Of course, people make mistakes, mis-speak etc. But if verbal sworn evidence is self-contradicting does rise to the level of proof to show that not only does the narrative not fit but that the story was fabricated? This is strictly a "he-said, she-said" type scenario. Arguably, one story makes sense, the other does not. How can that be taken to the point of showing fraud through perjury? Without a recording or transcript, of course. Just to make it that much harder. This is related: perjury is "the offence of willfully telling an untruth or making a misrepresentation under oath".
Laws criminalizing perjury are not about being mistaken or less believable in your testimony. The crime is, very narrowly, stating something which you do not believe to be true, while under oath. If you make a statement that happens to be untrue but you believe it is true (you are mistaken), that is not perjury. In the US, moreover, you have to assert something literally untrue, not simply say something that could be interpreted as being untrue. Rental arbitration hearings are nothing special, except that witnesses may or may not be sworn under the particular state's laws. If a witness is sworn and unambiguously asserts "Jones gave Smith $1,000 at that time", and another sworn witness asserts "Jones did not give Smith any money at that time", that might suggest that one witness testified as to something that they did not believe to be true. It might also show that they were standing in different places. Even if the circumstances show that the two witnesses observed the same facts, you would have to prove beyond a reasonable doubt that one party knew at the time that their statement was false. It is also possible that one witness made mis-remembered or misinterpreted what they saw. They might say or write something else (under oath, or elsewhere) that establishes that they knew better. An example is US v. DeZarn, which clearly established that the defendant could not have believed the statement that he testified to. With no official record of what a party testified to, it may not possible to establish beyond a reasonable doubt that a party committed perjury, since it can be reasonable to doubt claims of what he actually testified to. The defendant's attorney may, however, have to create such a doubt. Some answers could be perjurous if the question and answer are short enough, for example "Did you cash the check?" "No", if witnesses to the hearing testify convincingly that this exchange took place.
The burden of proof is always on the plaintiff (except for counterclaims brought by the defendant against the plaintiff). In your example, the businessman has to prove that he did not rape her.
In closing arguments, an attorney should only refer to evidence that was admitted at trial. In opening arguments, an attorney may refer to evidence that the attorney reasonably believes will be admitted at trial, and if the attorney has grounds to admit the transcript as an exhibit, could do so. If not, the attorney could still reasonable state: the evidence will show that an arresting officer described Mr. Jones as &quot;crazy&quot; without showing a transcript or explaining where it comes from (on the theory that the officer will either testify to that effect at trial or will be impeached at trial with the transcript for testifying in a contrary manner). Usually the transcript can usually be admitted only for impeachment, so usually it wouldn't be admissible absent contrary testimony at trial. But there are exceptions that apply to that rule which could make it admissible and hence proper to reference or show in opening arguments.
In general, signing means you cannot deny the accuracy of the information in the future In general, there is no prohibition on knowingly stating falsehoods under the law. That is, it is not illegal to lie. Exceptions include when you are under penalty of perjury (e.g. on oath in court), when you are making certain declarations to government (e.g. your tax return), you are acting dishonestly to cause gain or harm others (e.g. fraud), etc. However, by signing the document, you may create a legal fact that is independent of the real-world facts. For example, if you sign a receipt for $1,000 then you create a legal presumption that you received $1,000 even if there was actually only $500 in the envelope. You would need some pretty spectacular evidence to overcome that presumption. Now, I don’t know what you are signing that has factual errors in it but, if they are material errors, don’t. Just don’t.
When it comes to the obligation to tell the truth, there isn't all that much difference between a lawyer's obligations and those of a pro se litigant -- at least as far objective truth. But not every question has a single truthful answer. Professionalism rules impose some higher standards on lawyers in cases that are a bit murkier than just asking, &quot;Were you at the Capitol on January 6?&quot; In the United States, the analogous rule lays out some bright-line rules. Rule 3.3: Candor Toward the Tribunal (a) A lawyer shall not knowingly: make a false statement of fact or law to a tribunal or fail to correct a false statement of material fact or law previously made to the tribunal by the lawyer; fail to disclose to the tribunal legal authority in the controlling jurisdiction known to the lawyer to be directly adverse to the position of the client and not disclosed by opposing counsel; or offer evidence that the lawyer knows to be false. If a lawyer, the lawyer’s client, or a witness called by the lawyer, has offered material evidence and the lawyer comes to know of its falsity, the lawyer shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal. A lawyer may refuse to offer evidence, other than the testimony of a defendant in a criminal matter, that the lawyer reasonably believes is false. (b) A lawyer who represents a client in an adjudicative proceeding and who knows that a person intends to engage, is engaging or has engaged in criminal or fraudulent conduct related to the proceeding shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal. (c) The duties stated in paragraphs (a) and (b) continue to the conclusion of the proceeding, and apply even if compliance requires disclosure of information otherwise protected by Rule 1.6. (d) In an ex parte proceeding, a lawyer shall inform the tribunal of all material facts known to the lawyer that will enable the tribunal to make an informed decision, whether or not the facts are adverse. Subsection (a)(1) gives a good example of where the duties of honesty diverge for lawyers and pro se parties. If a plaintiff tells the court honestly -- but mistakenly -- that he lost $1 million in profits, but later discovers that he only lost $100,000, his lawyer has a clear obligation to correct that statement for the court; the pro se plaintiff's obligation is not clear. Similarly, if a plaintiff tells the court that he is entitled to those lost profits if he can prove elements A, B, C, and D, but later learns that the Supreme Court has also imposed a requirement that he prove E, the lawyer has an obligation to notify the court of this development; the pro se plaintiff does not. On the &quot;overriding&quot; language: I don't read it as generally having any effect on a lawyer's duty to be honest to his client. Instead, it means that the lawyer's duty to the court overrides the lawyer's duty to the client. In either of the above hypotheticals, for example, the lawyer acted honestly and ethically in presenting his evidence and argument, even though his statements turned out to be false. Correcting the record on either point would reduce or possibly eliminate his client's likely recovery and be against his client's best interests. Once the lawyer discovers the error, he is therefore faced with a conflict of interest: he has a duty to act in his client's best interest, but he also has a duty of honesty to the court. Chapter 13 says that his duty to the court overrides his duty to his client.
Unless you received an order from the court prohibiting contact, it might be legal; but it's probably not the best idea. Let the lawyers handle it Attorneys have far better, more effective means of dealing with this situation than the course of action you describe. Lawyers have productive tools to accomplish the job and they know how to use them. For example, assume the best-case-scenario results from your idea and you get the other side to admit their affidavit is fallacious in some way. "Aha!" you shout. "Success! Daylight!" But then what? It's not on record. You can't testify to the admission because that's hearsay. Now imagine they next share this information about your little conversation with the counterparty that had them sign the affidavit in the first place. After first being alerted of your concerns, they both now act in concert to shore up their stories and you never see that "daylight" again. Contrast that outcome with one where your guy or gal's attorney deposes the witness under oath, gets them to concede to your version of the facts then introduces the deposition as favorable evidence at trial. That's a much better outcome for "your side." Wouldn't you agree? Be wary of unintended consequences Generally speaking, such direct contact between the parties is often problematic and rarely helpful. (Except, in some cases, when direct contact between the parties leads to a negotiated settlement. Which happens far less often than the direct contact going sideways making the situation even more intractable.) Before you launch off on your own and do something that might be counterproductive. First, identify the areas of the affidavit that you think are inaccurate. Give that information to the party you support, then have them run it by their attorney to figure out the best way to handle the situation.
You don’t need to hire an attorney If you like, you can represent yourself. Just like you can build your own house, repair your own car or amputate your own limb. You only need to be a lawyer if you are representing someone else. However, there is a saying that goes: A person representing themselves has a fool for a client. Your lawyer is a professional, you aren’t. They know what to do when the other side says “Objection, facts not in evidence” or how to correctly fill out, file and serve a pleading; do you?
Based on the question, this was not perjury; if the officer did not review the footage, the fact that his testimony was in error indicates a mistake, nothing more. To even consider a perjury charge, the prosecuting authorities would need evidence that the officer knew the testimony was wrong when he gave it. You do not indicate the jurisdiction, so nobody can say whether an appeal would lie (since new evidence has come to light), whether the conviction could be quashed for procedural failure (if multiple requests for evidence were really not received) or whether a complaint could be made against the prosecutor, the defence lawyer, or even the judge. But no case has ever been strengthened by brandishing about words like 'perjury' without being able to substantiate them.
