Can one be banned from TfL services? Btp are often keen to advise that station staff are entitled at their own discretion to refuse members of the public carriage or entry to the stations like any privately owned business and it becomes then a civil matter between the parties. But tfl is paid for by the public as an essential service with taxes. Other private businesses are able to permanently ban one from admission to their places of business. Can tfl do the same?
Yes. Here is a tally of bans from a four-year period. Here is one specific example.
The First Amendment forbids the government from abridging your freedom of speech. There is no (federal) law against your private employer doing so. A good summary is https://www.americanbar.org/publications/insights_on_law_andsociety/15/winter-2015/chill-around-the-water-cooler.html
Say I build myself a faraday cage/wave screen around my house, potentially resulting in poor nework coverage for my neighbours. Questions about land property and constructing permits apart, can I be sued for that? By the network operator? by the neighbours? In most countries, the use of the radio spectrum is regulated (who may send what on which frequency, at which power, etc.). As part of these regulations it is usually forbidden to interfere with the reception of radio waves. So if what you do causes your neighbours to have reception problems, then yes, that will most likely be illegal. In France, the government agency responsible for these problems is ARCEP (Autorité de Régulation des Communications Électroniques et des Postes). If someone notices reception problems, they can complain to ARCEP, as explained for example on the page Le traitement des plaintes en brouillage ("Handling of complaints about jamming"). While you will probably not go to prision for jamming reception, you could have to pay a significant fine. This article on cell phone jamming mentions a penalty of "up to six months in prison or a 30,000 € fine" for "selling or installing" a cell phone jammer. In addition to that, anyone harmed by the reception problems could sue you in civil court and try to collect financial damages (how much that would be will be up to a judge to decide). That said, note that a faraday cage around your house should not hinder reception outside your house. A faraday cage only influences reception inside the cage, not outside. However, that is off-topic here :-).
Under 42 USC 2000a(a): All persons shall be entitled to the full and equal enjoyment of the goods, services, facilities, privileges, advantages, and accommodations of any place of public accommodation, as defined in this section, without discrimination or segregation on the ground of race, color, religion, or national origin. So a business may be generally prohibited from discriminating against you on the basis of your religion, but I don't know of any law that requires stores to accommodate whatever aversion or hostility you may feel toward gay people or their allies. On the contrary, such businesses have a First Amendment right to display such decor. So legislation that required them to stop speaking out in support of nice gay people would be struck down as unconstitutional.
You can basically take pictures of anything from your property if it is "public" (i.e. easily visible from your property). People on the road are in public, and have no reasonable expectation of privacy. The basic restrictions on photography are (1) you cannot trespass (you aren't), and (2) you cannot take pictures of certain government operations (e.g. airport border crossing – certain aspects of government prohibition may require lawsuit to rein in government policy that is at odds with the 1st Amendment; also secret military installations, for which there is specific law, 18 USC 795). Commercial exploitation of people who you photograph is strongly protected in California, and that is it.
A business has the right to refuse service, except in the case of unlawful discrimination. &quot;Sued us&quot; is not a protected characteristic. Unless part of the settlement was that the business must serve that customer in future, there is no way this could be considered contempt.
You are right, the entry and exit photos are only evidence that you were there. This is something they need to prove so the photos may only be for that. Their statement that you didn’t display a valid ticket/permit is, at present an unevidenced assertion. If you contest this, they will provide evidence that you didn’t (e.g. the actual records they refer to) and you would provide evidence that you did and, if it goes to court, the judge will decide what evidence they prefer. As this is not a criminal matter, they need to prove the offence on the balance of probabilities. However, there are almost certainly administrative remedies which will allow you to contest the fine without going to court. This would involve you sending them a copy of the permit and them assessing whether their belief that you didn’t display it is justified or not.
No. Just because some building is "owned by the public" or State, doesn't mean it's public property. A state's national guard installation comes to mind immediately. State workers' offices are not public places. Airport hangars/buildings/runways. You can't just go hang out in the DPW garages.
