Is the prohibition of narcotics mandated by an international treaty? Possession of narcotics is of course illegal in many jurisdictions. Recently there has been talk of relaxing or eliminating prohibitions on the sale and possession of drugs. Are there any international treaties or supranational legislation that would be breached if, say, the United Kingdom legalised narcotics? If so, which countries are similarly bound?
Yes, there are international treaties that the UK would breach if they legalised narcotics. Those are: The Single Convention on Narcotic Drugs, 1961 The Convention on Psychotropic Substances, 1971, and The United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, 1988 The majority of UN members are bound by these treaties: 185 of 193 for the 1961 and 1971 treaties, and 189 of 193 for the 1988 treaty. For a full list of signatories and of parties to the treaties, click 'Status of Treaty Adherence' under each treaty. As to what specific breach the UK would commit if narcotics were legalised, the answer can be found in one of the articles of the 1961 convention: Article 4. General obligations The parties shall take such legislative and administrative measures as may be necessary: (a) To give effect to and carry out the provisions of this Convention within their own territories; (b) To co-operate with other States in the execution of the provisions of this Convention; and (c) Subject to the provisions of this Convention, to limit exclusively to medical and scientific purposes the production, manufacture, export, import, distribution of, trade in, use and possession of drugs. In other words, we are bound by this treaty to enact legislation to ensure that the use and possession of drugs is limited only to medical and scientific use.
To pick up on your comment 'Does this mean if I wish to build a chair for personal use, then since trade of chairs exists between states, Congress has the authority to outlaw possession or manufacturing of chairs?': Yes. For example, the US Congress can legislate to prohibit a farmer from growing wheat for use on his own farm, on the basis that there is interstate trade in wheat and therefore the Commerce Clause permits Congress to regulate the growing of wheat: Wickard v Filburn (1942) 317 US 111. If you grow marijuana, or build a chair, or whatever, you conceivably affect the number of marijuanas, chairs, etc that are traded between states. Therefore you affect interstate commerce. Therefore the US Congress can regulate you. The fact that your marijuana or your chair or your what is trivial in the scheme of the national economy is irrelevant if the aggregation of all regulated marijuana, chairs or wheat is significant: 317 US 111, 127-128. If the law didn't prohibit possession of marijuana absolutely but instead prohibited, say, the carrying of marijuana in schools, then the US Congress might have trouble relying on the Commerce Clause: see United States v Lopez (1995) 514 US 549 and replace 'marijuana' with 'handguns' (OK the marijuana/handgun analogy is bad but hopefully this illustrates that there are at least some limits on Congress' power -- it's not just 'any physical object that relates whatsoever to interstate trade therefore unfettered federal legislative power').
It is not correct to say that drugs are, for example, broadly illegal in many western countries Some specific drugs, or specific categories of drugs, are illegal in certain circumstances, by specific statutes. Which ones vary by jurisdiction. So the analogy breaks down. As for the main question, if by &quot;software cracking&quot; is meant creating a modified version of the software that operates differently, for example by-passes authentication, or allows unlimited &quot;lives&quot;, that would most probably be creatign a derivative work of the software. Creating a derivative work, even if it is never distributed, is copyright infringement under US law: 17 USC 106 (2) lists as one of the exclusive rights of the copyright holder the right to prepare derivative works based upon the copyrighted work; This also covers the right to authorize preparation such works. So merely creating a &quot;cracked&quot; version of the software is technically infringement. However, infringement (of this sort) is not a crime, and no border officer or other government official will care about it in the slightest. It is up to the copyright owner to take legal action, normally by filing suit. If the modified software is never distributed nor advertised, it seems unlikely that the owner will ever even learn of it, and less likely that the owner will sue if s/he does learn of it. Damages in such a case, if the owner brought one, would probably be small, indeed not enough to make it worth the owner's time and trouble. If the cracker starts with an instance of the unmodified original software,m and edits it in place, never making a new copy, s/he is still preparing a derivative work, and (unless permission was obtained, or the work constitutes a fair use) it is still, copyright infringement If the modified software were posted online, the owner could send a takedown notice to the hosting site. If it were being sold, then a suit would be more likely. If what the cracker creates is not a modified version of the software, but instructions for modifying it, it is less clear that that would even be infringement. If the instructions are for evading an access control mechanism, that might be unlawful under 17 USC 1201 the anti-circumvention provisions of the DMCA. But again it would be up to the owner to take legal action, the government will not care until and unless the owner takes action. (a) The subject matter of copyright as specified by section 102 includes compilations and derivative works, but protection for a work employing preexisting material in which copyright subsists does not extend to any part of the work in which such material has been used unlawfully. (b) The copyright in a compilation or derivative work extends only to the material contributed by the author of such work, as distinguished from the preexisting material employed in the work, and does not imply any exclusive right in the preexisting material. The copyright in such work is independent of, and does not affect or enlarge the scope, duration, ownership, or subsistence of, any copyright protection in the preexisting material. The above answer is specific to the united-states but on this point the laws of other North American and European countries are, i believe, similar, as is the Berne Copyright Convention, at least on the matter of derivative works.
You could almost define a country as, "an entity that can defend itself against invasions." Non-sovereign entities are indeed generally prohibited from deploying lethal autonomous defense systems like booby-traps. But governments and state-like actors, as a matter of practice, choose their own rules. laws-of-war and international-law are not like "regular" law: When it comes down to it, states only follow international conventions and treaties to the extent that they consider it to be in their own interest to do so. If you start mining your property, you will probably be forced to stop by local law enforcement. If a warlord starts mining his borders, he's going to get away with it until someone with more power convinces or forces him to stop. Was it "illegal" for Turkey to shoot down a Russian military aircraft? One could cite all sorts of laws and conventions to answer that question. But in practice the consequences of that act are limited to whatever Turkey allows, or to what Russia and its allies can impose on Turkey.
But even then, to my understanding, a contract can't prohibit a party from seeking legal remedies. You are mistaken. A contract settling a bona fide dispute regarding people's legal rights can mutually (or unilaterally for that matter) release or waive their legal rights. In fact, a waiver or release of rights is routinely a part of a settlement agreement. Hundreds of thousands, if not millions, of such agreements are entered into every year and they are almost always enforced. Sometimes, but not always, a settlement agreement will also call for a dismissal of a case with prejudice, which (roughly) means a dismissal that prohibits refiling a case involving the same subject matter.
The legal hook is reported to be §129 of the Code of Criminal Procedure, which authorizes use of force to disperse an illegal assembly, which this sort of is. No statute that I can find states that police can smack lawbreakers who are forced to disperse, but as is common in common law countries, the laws of India are not fully explicit on that which is allowed or forbidden for police to do. As this article indicates, systematic limits on police use of force remain to be developed.
It is definitely illegal in Russia as well, but the police will do nothing. Previous activity of this group included forcefully attacking people who tried to speak to a girl who disliked it and handling over such people to police to get fined "for hooliganism". Usual practice in Russia is to beat the people whom the random girls around dislike. This group stepped a bit further, involving police. They use illegal or questionable methods, definitely. But they use them in a manner that people would be unlikely to complain to police because they themselves either did something illegal or public opinion is not on their side. The police usually will do nothing even with much more serious violations, like beating somebody.
The US has jurisdiction because you committed a crime in the US. Canada has jurisdiction because you committed a crime in Canada. As added complications, if you are a Mexican citizen then Mexico has jurisdiction and if your victim is Chinese then China has jurisdiction. If you get arrested on an Interpol warrant in Spain then Spain has jurisdiction. And so on ... Your implicit assumption is that jurisdiction is exclusive, it isn't. Any country (or sub-national jurisdiction) that claims jurisdiction has jurisdiction, at least to the extent of testing that claim. Whether any given polity has jurisdiction depends on the particular law involved, some laws are only applicable within that countries borders others are extra-territorial, some are applicable to citizens but not non-citizens or vice-versa, etc.
