Is it illegal to make a puppy fur jacket? I watched 101 Dalmatians for the first time and wander: Can dogs or cats be raised like farm animals for the purpose of food or fur? What species of animal is not allowed for product other than endangered species?
USA: 19 USC §1308 prohibits the import, export, or interstate sale of cat or dog fur: (1) In general It shall be unlawful for any person to— (A) import into, or export from, the United States any dog or cat fur product; or (B) introduce into interstate commerce, manufacture for introduction into interstate commerce, sell, trade, or advertise in interstate commerce, offer to sell, or transport or distribute in interstate commerce in the United States, any dog or cat fur product. A brief summary of state laws can be found this article at the Animal Legal &amp; Historical Center: A handful of states have laws concerning dog and cat fur. Alabama, Delaware, New Jersey, New York, Pennsylvania, and Virginia prohibit trade in domestic dog or cat fur. Virginia also prohibits killing a dog or cat for its fur, while Florida prohibits killing a dog or cat with the “sole” intention of either selling or giving away the pelt of the animal. In Oregon, a person cannot buy or sell dog or cat fur that is obtained from “a process that kills or maims the cat or dog.” UK: In the UK, the trade in cat &amp; dog fur was banned by the The Cat and Dog Fur (Control of Import, Export and Placing on the Market) Regulations 2008, which were in turn passed to follow EU Regulation #1523/2007: The placing on the market and the import to, or export from, the Community of cat and dog fur, and products containing such fur shall be prohibited. More information about the legal consequences and enforcement of this law can be found at this review article. Finally, note that Cruella de Vil's actions did not involve trade in dog or cat fur; she acquired most of the puppies via legal means, and was planning to kill and skin them for her own personal use, not to sell the resulting articles to other parties. As such, I believe that her planned course of action would have been legal in the UK and in all US states except Virginia. The only unquestionably illegal act she undertook was directing Jasper &amp; Horace to steal Pongo's and Perdita's puppies.
It isn't clear that the example you give is illegal police action, but let's assume that it is for the sake of this question, since it doesn't affect the analysis. If possession is not compelled, then it is voluntary.
You have misread the DMLP page. In Pennsylvania, it is illegal to record a conversation if you are a party and if the other party does not consent. The fact that federal law doesn't ban something doesn't mean that states can't ban it. There is generally a presumption that when both the feds and the states can legitimately regulate something, the feds weren't trying to preempt all state laws on the topic. While people often say "federal law takes precedence over state law," the normal rule is that both laws apply; the federal law only blocks the state law if the feds wanted to block said state laws. So far as I can tell, the federal law has never been held to preempt two-party consent laws; the point of the federal law was to restrict recording, not extend it. It's like how federal law doesn't prohibit taking hostages inside the US to coerce a private company into doing what you want (anti-terrorism laws might, I guess, but the federal hostage-taking law doesn't); while the federal law excludes most hostage-taking in the US, that doesn't mean that it's legal to take hostages. Congress sometimes wants to establish nationwide standards for something, but the presumption is that they didn't.
It's questionable, because if you design your own visual interpretation of the T-Shirt then it isn't necessarily the one from the book and thus your art has it's own copyright. However, if the current Copyright Holder and Possible Trademark owner is selling the shirt it could be an issue because yours is not official but being sold as one. If you're making it for non-sale and just cosplay, than you have a better arguement.
I think the Washington law and order is fairly clear: you must stay home unless you are engaged in certain allowed activities. The underlying law, RCW 43.06.220(h) empowers issuing an order prohibiting "Such other activities as he or she reasonably believes should be prohibited to help preserve and maintain life, health, property or the public peace". Therefore I can walk my dog. When I do, there are a lot of people also out walking their dogs, so that provides a letter-of-the-law permitted exception to the stay-at-home order. Nothing in the order specifically addresses the situation where you pause your dog-walk to talk to a neighbor (the "appropriate social distancing" sub-rule only applies to recreational departures from your home). It is well-established that the central legal issue is what the "compelling government interest" is, and whether these restrictions fail on grounds of narrow-tailoring or least-restrictiveness. The failure to include "go to your brother's place for lunch, provided you follow appropriate social distancing guidelines" as a permitted activity is a candidate for not being least-restrictive. The problem is that the courts will not engage in an infinite regress of second-guessings about whether certain measures are "truly necessary". There is a SCOTUS challenge where the Pennsylvania Supreme Court upheld that's state's order, but a SCOTUS order requires the state to reply to a petition by Monday. The "status quo" is that these orders are legal, until someone constructs a compelling argument that they are not, and that matter is then resolved in favor of petitioner by SCOTUS (which has not happened). So far, governors have prevailed at the state level.
There is no law against feeding birds, in Chicago or elsewhere in Illinois. The city does have a law against keeping pigeons whereby It shall be unlawful for any person to import, sell, own, keep or otherwise possess any live pigeon within any area designated as a residence district under the Chicago Zoning Ordinance. but this does not extend to feeding pigeons. Rumors may have gotten started because the DNR had recommended removing bird feeders for (bird) health reasons, but that is not a legal prohibition and anyhow has since expired.
It is the terms of the lease that govern what you may and may not do, so if pets are not disallowed, they are allowed. You are not a party to the contract between the landlord and the agent, so whatever the landlord may have told the agent is technically irrelevant to you. However, this may be an indication that the landlord plans to change policy; it might also mean that the agent misunderstood something. That is where you stand legally.
You can write anything you want (basic First Amendment protections): the question is whether one would be liable for damage that arises from what you're written, or whether you can distribute what you've written. Distribution may be restricted, thanks to the Commerce Clause (hence FDA regulations, which figure prominently in the analysis). Most software writers are not medical practitioners, and vice versa, and what the software writer does is implement something described by a competent medical practitioner. It is logically possible that a med. practitioner might also try to write software (no problem) and distribute it (possibly a problem); or, a software writer might read up on something on Wikipedia and try to implement it (again, no problem) or distribute it (possible problem). Damages can be sorted into two categories, implementation errors and scientific errors, and having ruled out deliberate sabotage, we are left with negligence. If the software writer failed to use suitable care in writing code that sums a set of numbers, the software writer has been negligent. If the person purporting to have the qualified scientific knowledge mis-states the formula, that person has been negligent. It is possible for many parties to be negligent (the programmer failed to be diligent in understanding the software requirements; the medical professional failed to adequately explain what was required of the program). The FDA does regulate medical devices, and "device" is construed pretty broadly (condoms are non-exempt class 2 medical devices). There is FDA guidance on medical software which makes it clear that the device manufacturer shoulders the regulatory burden. Anytime you manufacture a tangible thing (which is within the scope of FDA regulation for medical devices), you have to have the thing approved. Many (most?) medical devices implement software, and are thus within the scope of FDA scrutiny. It is not illegal to write software that ends up being implemented in an unapproved medical device, but the unapproved medical device itself is illegal. It is reasonably likely that purported medical software (not a gadget with software build in) would be held to be a non-exempt device. To know if something is exempt, you would look at the exemptions list, and determine that your program (or thing) is not on or implied by anything on that list. The visual acuity eye chart is a class 1 exempt item, as is the manual toothbrush. There is no way to specifically look for things that are only software, or that contain software, so the search through the list would have to be guided by knowledge of the subject area. Canada is helpful in explaining when software is a regulated medical device. This is non-probative w.r.t. US law but gives you an idea what is likely to be considered a "device". Under Canadian law, the software would be clearly a regulated medical device. The FDA has a power-point that attempts to say something about the matter which warns you that you are on your own and "You will need to go back to study and use the source regulatory documents" to make the determination. Eventually, slide 13, they hint that if you intend the software to be used in diagnosis, prevention, or treatment, then it is a device (so, yes, the aforementioned software would be a device, and probably not exempt from regulations). General purpose software (word processors, web browsers, communications software, etc.) are not indented to be used for a regulated purpose, although they can be so used, and thus they are probably not subject to FDA regulation. There is a murky relationship between regulatory approval and liability. Being approved by the government does not convey immunity to negligence suits (see Wyeth v. Levine), but being approved can have weight in determining whether a party was negligent, since regulatory scrutiny ostensibly filters out errors that could have been caught. Federal approval does not preempt state tort law, as the court ruled. Regulations pertaining to medical devices hold for anything that qualifies as a device, and is not defined (negatively) in terms of disclaimers. If you sell a medical device but label it saying "this is not a medical device, it is not created by a competent medical practitioner", that doesn't make it not a medical device. Unfortunately, what counts as a regulated device is based on intended use, and there is an obvious connection between disclaimers and intentions. Taking MS Word as an example, MS does not as far as I know say that "Word is not intended to be used as a medical device". It can certainly be used to diagnose, teat, and prevent medical conditions, but so too can a screw driver or pretty much anything else. The number of non-medical uses vastly outweigh the medical uses, so it would be deemed not to be a regulated device. A program which prescribed a set of prayers to be uttered in case of illness would be subject to First Amendment override of any FDA regulations. Quack medical devices are prohibited (that's why there is regulation of devices in the first place), but discerning the fine line between permitted actions based on nutty beliefs and forbidden actions is not easy. The FDA also has guidance on the distinction between "Complementary and Alternative Medicine", which does not clearly state that, for example, a software reading of your cakra-energies based on a computer program's questions is not a medical device. They do say of mind-body medicine (mentioning yoga, biofeedback and tai chi as examples) that "CAM practices in this domain would not be subject to our jurisdiction under the Act or the PHS Act", but then say "any equipment or other products used as part of the practice of mind-body medicine may be subject to FDA regulation, depending on the nature of the product and its intended use" (hence a yoga-enabling program may be subject to regulation).
