Can a power of attorney be used for criminal matters? Can a layman with a power of attorney lawfully represent someone else in criminal matters?
Not in jurisdictions I am familiar with. A "Power of attorney" is a power to act as an attorney-in-fact, not to act as an attorney-at-law. A layperson practicing law for someone other than herself is usually the unauthorized practice of law and is illegal in most jurisdictions. It would be permissible if a jurisdiction carved out an exception for a particular kind of case, but they generally don't and are very unlikely to do so in a criminal case. For example, in Washington State "Limited Practice Officers" can assist people with one of a very limited set of civil legal forms that do not need modification. There may be some exceptions, but they would be more likely to occur before a matter becomes criminal. For example, the accountant who represents a taxpayer before the IRS, or the agent who files a form containing perjury to a federal agency like the post office or homeland security on your behalf. So it is very unlikely, but if it is important to you you can ask someone familiar with your kind of case in your jurisdiction.
This is an amusing idea, but ultimately it seems frivolous: How does one establish the physical presence of a corporation in a car? Yes, corporations have some of the legal rights and liabilities of people, but they are not people. And there are plenty of rights a person has that a corporation does not. For example (at present) a corporation can't be a party to a marriage. The closest a corporation comes to any corporal presence is the address listed of their agents.
By my understanding you should not be held criminallly liable. In order to be held guilty of a crime the prosecution needs to show the elements of the crime are met. One of these elements is "mens rea" - ie guilty mind/intent. According to your question you lacked intent to commit the crime, so the prosecution can't prove it, so their case must fail. Note that in some places there are "crimes" which are strict liability - I'm ignoring these abominations here, as they are generally a grey area between criminal and civil law where freedom is not at stake and do not seem in the spirit of your question.
Every state requires at least two witnesses to a will unless it is entirely written in your own handwriting. A lawyer as a witness is fine. A spouse as a witness is not ideal as she would be an interested party if there was a dispute over whether it was executed. It may not be prohibited, but I would never do that in my practice ever. I discontinued a will signing just last week because we only had a lawyer and a spouse and not other witnesses. I would be somewhat concerned.
A problem with the question is that it uses the loaded term "victim". If you change the question to "Are there actions that you can perform involving another person, which are crimes even if the other person consents to participating in the action", then there are very many. Selling alcohol to a minor; selling heroin to anyone; selling sex in most US jurisdictions; selling firearms to a convicted felon. Also, for a physician to assist a person in suicide, in most states. Formerly in the US, various forms of sexual intercourse were acts that consent did not make legal. Whether or not the person is a "victim" in these cases is open to debate. In the case of physician-assisted suicide in Washington, the doctor is allowed to prescribe (oral) drugs that the person ingests: only a doctor is permitted to do this, both under the DWD Act and as a consequence that only a doctor can prescribe the drugs. There seems to be a belief that it is a crime to assist a person in committing suicide, which is probably correct if the assistance is shooting the person in the head, or in general directly causing the death (thus, "I give you permission to shoot me in the head" doesn't cut it). But from what I can tell, it is not generally against the law in Washington to help a person who commits suicide (e.g. supplying the means of self-dispatching). In some countries, suicide and helping with suicide is illegal, e.g. in Kenya Penal Code 225 says Any person who (a) procures another to kill himself; or (b) counsels another to kill himself and thereby induces him to do so; or (c) aids another in killing himself, is guilty of a felony and is liable to imprisonment for life. No exception is created if the person consents to being aided to kill himself.
If a defendant has committed a crime, they would choose to self-represent to ensure that no one else would know about the circumstances of their crime. Although lawyers are ethically bound to not disclose information that would not be in the interest of their client, the decision to breach this duty would be up to the sole discretion of the individual in question. In cases where the exchanged information may used to provide evidence against the client, the lawyer is compelled to disclose the truth to the courts/law enforcement. This is deeply misguided. Criminal defense lawyers usually represent people who are guilty and there is no ethical problem with doing so, nor does this mean that the lawyer will disclose privileged information that is prejudicial to the defendant in the course of the representation. The notion that a lawyer would be compelled to testify against his client to the courts/law enforcement is simply not how the system works. It is true that a lawyer cannot ethically put you on the stand to offer testimony when the lawyer knows that your testimony to the court will be an outright flat lie, and that this lie is your strategy to prevail in your defense, but that is the sole meaningful limitation on what a lawyer can do for you. However, I can't think of a single instance, in which a desire to defend yourself at trial with a lie has caused someone to represent themselves. Usually, someone with that kind of motive will simply lie to their lawyer as well. It never makes sense to represent yourself if you are innocent and want to be acquitted of the charges against you. But, keep in mind that this is a small subset of all criminal defendants. Criminal defendants are overwhelmingly guilty of something. Usually, a criminal defense lawyer works to either exploit prosecution mistakes or lack of knowledge that prevent the prosecution from proving that guilt, or work to make sure that the defendant is not convicted of a more serious crime than the one committed, and/or work to see to it that their client does not receive an unnecessarily harsh sentence when alternatives are available. In real life, people represent usually themselves, either because they are denied access to counsel (which can be done in a criminal cases where the prosecutor waives the right to seek incarceration as a sentence), or because they are "crazy". Many people who represent themselves in a criminal cases do so because they want to proudly claim that they committed the crime as a means of obtaining of forum for public recognition of what they believe was righteous action even if this could lead to their death. Many terrorists, domestic and foreign, fall into this category. For example, the fellow committed a massacre at a Colorado abortion clinic tried to do this (if I recall correctly, he was later found incompetent to face a trial and has been committed to a mental institution until he becomes competent, if ever). Other people represent themselves out of a strongly felt guilt that they feel a moral duty to confess to, even if this means that they will face severe punishment for doing so. One subset of this group of people are people known as "death penalty volunteers" who try to get sentenced to death and try to waive all appeals and post-trial review. Sometimes they also plead guilty in the belief (often, but not always, inaccurate) that their swift guilty plea when they aren't actually guilty will protect someone else whom they know to be actually guilty. Other people represent themselves because they have deeply held, but paranoid and inaccurate views about the legal system such as members of the "Sovereign Citizens Movement" who think that if they say the "magic words" that they cannot be convicted and that lawyers are a part of a conspiracy designed to prevent them from doing so. Another situation that comes up is when an affluent person who is not entitled to a public defender as a result, chooses to represent themselves, usually with respect to a fairly minor charge like a traffic violation that carries a risk for a short term of incarceration, to save money. But, this is rarely a wise choice. But, unless you plan on pleading guilty or being found guilty at trial, self-representation does not make sense, and even if you plan on pleading guilty, a lawyer is usually worth it. For example, even if the direct consequence of a guilty plea is minor, the collateral consequences of that conviction (e.g. loss of eligibility to work in certain jobs and/or deportation and/or loss of a right to own a firearm) may be consequential and something that a non-lawyer would not realize was happening. Or, maybe you think you are guilty of crime X so there is no point in fighting the charges, but actually, the language of that statute has been defined in a manner that means you are really only guilty of less serious crime Y.
The most apparent potential offences would be under 18 U.S.C. § 1030, but these require the mens rea of &quot;knowingly&quot; or &quot;intentionally&quot; doing things without authorization, or doing so &quot;with intent to defraud&quot;, etc. See also the Department of Justice's manual entry on this family of offences. Particularly relevant is this quote: As part of proving that the defendant acted knowingly or intentionally, the attorney for the government must be prepared to prove that the defendant was aware of the facts that made the defendant’s access unauthorized at the time of the defendant’s conduct. Given your stipulation that the person has unintentionally viewed or downloaded the material without authorization, this would not be a violation of 18 U.S.C. § 1030.
Yes. This is legal and it is done routinely. It is called executing a document in counterparts. To be clear, however, as the language of the question is ambiguous on this point, each signature would have to be contemporaneously notarized by the person notarizing that particular signature. In each case that a notarization took place outside the country where the Power of Attorney is to be utilized, normally, it would be necessary to also obtain an apostille for that notarization. An apostille is an official declaration of a designated official in the country of notarization that the notary of the signature in question was, in fact, a notary in good standing at the time that the notarization was done.
