If you commit a crime in an airport, are you tried under maritime law? Airports occupy an interesting legal grounds, wherein they are not technically a part of the country they are in (hence tax-free purchases in duty-free), and yet still must obey some set of laws. By international agreement (though the exact name of the treaty or treaties escape me), any land (or water for that matter) that is not occupied or claimed by some sovereign nation, and is therefore not under the jurisdiction of any sovereign nation — such as space, unclaimed islands and the middle of the Pacific — is under maritime law. Does maritime law therefore apply to crimes committed in airports? Even more interesting, can someone who commits a crime in an airport physically located within a country he or she is not allowed to be in (no visa for example) be removed from that airport (and therefore allowed into the country) to stand trial? Update: After some additional research, it seems international airports, embassies and certain war-risk areas (i.e. the Green Zone in Iraq, also known as the International Zone of Baghdad) contain specified areas defined as international zones. These zones are not so much unclaimed as designated independent of the country they're in largely for purposes of diplomacy. Because of the, ahem, fuzziness of the law governing them, I'd be very much interested in an answer to the question, even if the wording on the question may have been a bit confusing to the first few people to see it.
For purposes of criminal law, in practice, airports in the United States are treated as part of the territory of the state (or district or territory) that they are a part of and of the United States. The scope of maritime criminal jurisdiction is defined at 18 USC 7. It states: The term “special maritime and territorial jurisdiction of the United States”, as used in this title, includes: (1) The high seas, any other waters within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State, and any vessel belonging in whole or in part to the United States or any citizen thereof, or to any corporation created by or under the laws of the United States, or of any State, Territory, District, or possession thereof, when such vessel is within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State. (2) Any vessel registered, licensed, or enrolled under the laws of the United States, and being on a voyage upon the waters of any of the Great Lakes, or any of the waters connecting them, or upon the Saint Lawrence River where the same constitutes the International Boundary Line. (3) Any lands reserved or acquired for the use of the United States, and under the exclusive or concurrent jurisdiction thereof, or any place purchased or otherwise acquired by the United States by consent of the legislature of the State in which the same shall be, for the erection of a fort, magazine, arsenal, dockyard, or other needful building. (4) Any island, rock, or key containing deposits of guano, which may, at the discretion of the President, be considered as appertaining to the United States. (5) Any aircraft belonging in whole or in part to the United States, or any citizen thereof, or to any corporation created by or under the laws of the United States, or any State, Territory, district, or possession thereof, while such aircraft is in flight over the high seas, or over any other waters within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State. (6) Any vehicle used or designed for flight or navigation in space and on the registry of the United States pursuant to the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies and the Convention on Registration of Objects Launched into Outer Space, while that vehicle is in flight, which is from the moment when all external doors are closed on Earth following embarkation until the moment when one such door is opened on Earth for disembarkation or in the case of a forced landing, until the competent authorities take over the responsibility for the vehicle and for persons and property aboard. (7) Any place outside the jurisdiction of any nation with respect to an offense by or against a national of the United States. (8) To the extent permitted by international law, any foreign vessel during a voyage having a scheduled departure from or arrival in the United States with respect to an offense committed by or against a national of the United States. (9) With respect to offenses committed by or against a national of the United States as that term is used in section 101 of the Immigration and Nationality Act— (A) the premises of United States diplomatic, consular, military or other United States Government missions or entities in foreign States, including the buildings, parts of buildings, and land appurtenant or ancillary thereto or used for purposes of those missions or entities, irrespective of ownership; and (B) residences in foreign States and the land appurtenant or ancillary thereto, irrespective of ownership, used for purposes of those missions or entities or used by United States personnel assigned to those missions or entities. Nothing in this paragraph shall be deemed to supersede any treaty or international agreement with which this paragraph conflicts. This paragraph does not apply with respect to an offense committed by a person described in section 3261(a) of this title. Often, law enforcement at an international airport is provided by a county sheriff or municipal police department in addition to the TSA (including air marshalls) which has narrower jurisdiction, in contrast to places like Indian Reservations and federal parks, which while within a state are outside state and local law enforcement jurisdiction (although the assimilative crimes act applies state law in many such circumstances). They are definitely not subject to maritime jurisdiction in the United States. Duty free status usually arises from a definition particular to tax treaty and not a global sovereignty definition.
Edits added below to outline Florida's laws based on OP's comment Jurisdiction does matter but here is a general answer regarding "stand your ground" laws. States that have so-called "stand your ground laws" each have their own language concerning the law. "Stand your ground laws" are often misunderstood but, generally, just mean that a person has no duty to retreat when using deadly physical force for purposes of self-defense or the defense of others. Your examples are more akin to "castle doctrine" laws which I touch on below. Note that all of these laws vary by jurisdiction. I've provided partial examples from Arizona, New York and California. Using deadly physical force for purposes of self-defense or defense of others is complex law and even a complete example from any particular jurisdiction will not be able to cover all circumstances. Each case will be determined by a judge or jury based on the facts of that particular case. Arizona's "stand your ground" statute, as an example, states: B. A person has no duty to retreat before threatening or using deadly physical force pursuant to this section if the person is in a place where the person may legally be and is not engaged in an unlawful act. "Stand your ground" simply means that a person doesn't have to first attempt to retreat before resorting to the use of deadly force. Arizona's statute regarding justification for self-defense states (emphasis mine): A. Except as provided in subsection B of this section, a person is justified in threatening or using physical force against another when and to the extent a reasonable person would believe that physical force is immediately necessary to protect himself against the other's use or attempted use of unlawful physical force. B. The threat or use of physical force against another is not justified: In response to verbal provocation alone; or To resist an arrest that the person knows or should know is being made by a peace officer or by a person acting in a peace officer's presence and at his direction, whether the arrest is lawful or unlawful, unless the physical force used by the peace officer exceeds that allowed by law; or If the person provoked the other's use or attempted use of unlawful physical force, unless: (a) The person withdraws from the encounter or clearly communicates to the other his intent to do so reasonably believing he cannot safely withdraw from the encounter; and (b) The other nevertheless continues or attempts to use unlawful physical force against the person. Note the phrase, "extent a reasonable person." This means that the actions of a person using deadly force will be measured against what a "reasonable person" would do in similar circumstances. Some states have a duty to retreat, particularly when in a public place, before using deadly force. New York, as an example, has a "duty to retreat" before using deadly force except in specific circumstances (emphasis mine): A person may not use deadly physical force upon another person under circumstances specified in subdivision one unless: (a) The actor reasonably believes that such other person is using or about to use deadly physical force. Even in such case, however, the actor may not use deadly physical force if he or she knows that with complete personal safety, to oneself and others he or she may avoid the necessity of so doing by retreating; except that the actor is under no duty to retreat if he or she is: (i) in his or her dwelling and not the initial aggressor; or (ii) a police officer or peace officer or a person assisting a police officer or a peace officer at the latter`s direction, acting pursuant to section 35.30; or (b) He or she reasonably believes that such other person is committing or attempting to commit a kidnapping, forcible rape, forcible criminal sexual act or robbery; or (c) He or she reasonably believes that such other person is committing or attempting to commit a burglary, and the circumstances are such that the use of deadly physical force is authorized by subdivision three of section 35.20. Castle Doctrine Laws typically refer to what one may do in their own home when it comes to the use of deadly force. Some states have extended the "castle doctrine" to include personal automobiles as well. California's "castle doctrine" statute, as an example, states that if one is in their own home and someone "unlawfully and forcibly" enters the home one can presume that the person in his or her residence "held a reasonable fear of imminent peril of death or great bodily injury": Any person using force intended or likely to cause death or great bodily injury within his or her residence shall be presumed to have held a reasonable fear of imminent peril of death or great bodily injury to self, family, or a member of the household when that force is used against another person, not a member of the family or household, who unlawfully and forcibly enters or has unlawfully and forcibly entered the residence and the person using the force knew or had reason to believe that an unlawful and forcible entry occurred. As used in this section, great bodily injury means a significant or substantial physical injury. In California's statute both the resident and the person using force to gain entry have to know or have reason to believe that an unlawful and forcible entry occurred. If a person simply entered an unlocked home then the resident would have to have some other reasonable reason to believe that they were in imminent peril of death or great bodily injury. Wikipedia has a reasonable entry on the adoption of "stand your ground" and "castle doctrine" statutes and gives a state-by-state breakdown of both. Note that these laws have seen a lot of change recently and any particular entry for a state may not be accurate. Florida's self-defense laws Florida's "Use or threatened use of force in defense of person" states: 776.012 Use or threatened use of force in defense of person.— (1) A person is justified in using or threatening to use force, except deadly force, against another when and to the extent that the person reasonably believes that such conduct is necessary to defend himself or herself or another against the other’s imminent use of unlawful force. A person who uses or threatens to use force in accordance with this subsection does not have a duty to retreat before using or threatening to use such force. (2) A person is justified in using or threatening to use deadly force if he or she reasonably believes that using or threatening to use such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony. A person who uses or threatens to use deadly force in accordance with this subsection does not have a duty to retreat and has the right to stand his or her ground if the person using or threatening to use the deadly force is not engaged in a criminal activity and is in a place where he or she has a right to be. Florida outlines the cases where use, or threatened use, of force is justified. Notice that in the law Florida specifically states that the person threatened does not have a duty to retreat. Florida also specifically states that a person has a "right to stand his or her ground" if the person is in a place where he or she has a right to be and is not engaged in criminal activity. Florida statute also specifically outlines the right to use self-defense within one's home and vehicle. Florida has a "castle doctrine" similar to what was outlined above and similar in nature to New York's and California's laws: The person against whom the defensive force was used was in the process of unlawfully and forcefully entering, or had unlawfully and forcibly entered, a dwelling, residence, or occupied vehicle, or if that person had removed or was attempting to remove another against that person’s will from the dwelling, residence, or occupied vehicle; Florida has a longer list of exemptions related to who may have used force to enter a home including ownership interest in the property or vehicle, children and grandchildren, the person who engaged defensive force was involved in criminal activity and law enforcement officers. Florida's Justifiable Use Of Force is chapter 776 discusses when force can be used. There was an attempt by the Florida legislature in 2019 to change the standard by which use of force could be justified from "reasonably believes" force is necessary to "a reasonably cautious and prudent person in the same circumstances would objectively believe" force was necessary. The bill was withdrawn in May, 2019.
In general this is protected by the first amendment. It is not in general a problem describing how one can one can do something illegal. But there are special cases to be careful with. You might want to do some research into the limits on free speech. It would be hard to provide an answer that fully covers all your different cases and you would need to be more specific about what illegal activity you want to describe. In describing how to do something illegal, you might accidentally share information that you are not allowed to share. When you post things online, this can be considered as publishing or exporting. Therefore certain export restrictions might apply. Also, It is illegal to publish bomb making manuals, with the knowledge or intent that this information be used to commit a federal crime of violence. See https://www.law.cornell.edu/uscode/text/18/842. There are restrictions on publishing material relating to cryptography without having an export license. Granted, this isn't necessarily related to publishing things that are illegal, but just to give an idea about how publishing/exporting knowledge can causes problems. See https://en.wikipedia.org/wiki/Export_of_cryptography_from_the_United_States ITAR (International Traffic in Arms Regulations) sets restrictions on what you can publish about arms. What you publish can't be “directed to inciting or producing imminent lawless action.” See for example https://en.wikipedia.org/wiki/Brandenburg_v._Ohio. One might imagine that you could get into trouble if someone interprets what you do as inciting or producing a lawless action. It might sound obvious, but you want to make sure that you have the right to share the information that you have. The information that you are providing might be copyrighted in some way.
Might depend on where you are. I think it's illegal in North Korea. In the US, it is legally encouraged, by the Commercial Space Launch Act of 1984, especially the part that says "Congress declares that the general welfare of the United States requires that the Administration seek and encourage, to the maximum extent possible, the fullest commercial use of space". Previously, Congress passed the Communications Satellite Act of 1962, which first expressed an interest in allowing commercial flights, but there was substantial opposition to non-government entities in space. There are a number of legal private space adventures from numerous countries. As Nate Eldridge points out, you still need government (FAA) permission. So it's legal to blast yourself into space in the same sense that it's legal to drive or to open a business.
In Germany, nuclear weapons are considered weapons of war, which are heavily regulated. In particular, under § 17 KrWaffKontrG, it is prohibited to develop or produce nuclear weapons or trade in them or acquire them from or leave them to another person or import or export them or transport them through the territory of the Federal Republic or in any other way take them into or out of the territory of the Federal Republic or in any other way exercise the actual control over them (my translation). Exceptions apply only to nuclear weapons controlled by the governments of NATO members, not to individuals. If you happen to come into the possession of a nuclear weapon without breaking the law yourself (e.g. if you inherit it from someone who illegally built it), it can and certainly will be confiscated under § 24 KrWaffKontrG.
Of course Unless you waived your right to go to court in the contract. For example, if the contract contains an arbitration clause, disputes must be arbitrated, you cannot use the courts. It is also possible that an English court may not have jurisdiction. For example, if the contract had a choice of forum clause requiring disputes to be resolved in the courts of the UAE, then an English court would possibly defer to that and refuse to hear the case. Whether you will succeed depends on the terms of the contract and whether the airline had a duty to provide you with accurate information. It is quite likely that the contract contains disclaimers as to the accuracy of information given. These may succeed in defeating your suit.
The private organizations, in difference to international organizations (the organizations, members thereof are the countries) or the countries are not subjects of international law. They are also not a subject of criminal laws, so they technically can't break the law. The people can. If the actions of such organizations will break some laws, the people staying behind that organization will be made responsible. Either it will be single individuals, or the whole organization might be declared criminal (such as mafia or a gang) and there everyone, including stakeholders or casual employees/contractors might be subjects to interrogation, arrest and sentence. As for the problem you describe, when the organization made something illegal under one jurisdiction, and the stakeholders are sitting in other country, where such actions are not illegal, they might only partially be safe. They might be arrested not only in the country where the legal actions are taken, but also in third countries, that have extradition agreements with that country.
International Humanitarian Law applies to all armed conflicts The Geneva Conventions are a part of the overarching body of this law. It applies to all armed conflicts, not just declared wars. An armed invasion by R of U is a conflict to which IHL applies irrespective of if it is a declared war or not. BTW, declared wars outside Africa and South America are virtually unknown since WWII
