Are &quot;exact change only&quot; policies legal? I parked in a garage that has an automated pay-to-park kiosk - you specify how many hours you wish to purchase, and then insert payment. For two hours of parking, the price was listed as $6. It was only after I inserted a $10 bill that I noticed the "exact change only" sign under the payment slot. So, I was effectively charged nearly twice what I should have been. It was only $4, but I felt like I had been scammed and I went to the main parking office to request my change. They told me I would have to contact the company that actually processes the payments. Am I legally entitled to my change? Or, did I "consent" to be ripped off because of the three words "exact change only"? My receipt even said that the total cost was $6, and that I paid $10.
You didn't consent to being ripped off. You did however fail to grasp the terms under which you were permitted to park on their property, and you failed to pursue an alternative (such as looking for change; using a credit card). It is possible that you should have known that this was a no-change-given machine, since one can often see that there is no mechanism on these machines whereby you can actually get change. However, if you have clear proof that you owed $6 and you paid $10, then 4 of those dollars are properly yours, and there is a reasonable chance that you could prevail in a suit against them. There is even a greater chance that they would refund the difference, just as a sensible business practice. "Exact change" is legal and can even be the law, especially in government-run transportation systems.
Your question isn't quite as simple as it sounds; some civil cases are tried before juries, and though a judge can give directions to a jury to give a particular verdict, they are not always required to obey; there are eighteenth-century English cases on the point that established that principle for most related jurisdictions. But your last sentence does have a simple answer: No. A judge usually takes an oath on assuming office, to administer the law without fear or favour. That means he will investigate the relevant law (with the assistance of the parties' lawyers), and enforce what it says. "This law would be unfair to the customer, so I will ignore it" would be just as bad as "The mechanic threatened to hit me with a wrench, so I find for him". Of course, most jurisdictions do have overriding principles of fairness; it may be that this contract term was not shown to the customer, so is not enforceable, or it may be that it is contrary to public policy to be uncertain what repairs will cost. But unless there is an explicit legal reason, the judge will have to find for the mechanic. It would be neither improper nor unusual for the judgment to include the sentence "This result is clearly unfair to the customer, and I urge the legislature to look at closing the loophole; nevertheless, the law is clear, and I find the customer must pay the increased price."
Bill and Jane are free to enter into a contract where, among other things, each provides valuable consideration; in this case Bill provides valuable lawn mowing services and Jane provides valuable money. In week No 1 they have negotiated the terms and the contract is complete when Bill mows the lawn and Jane pays the money. If Bill turns up next week without Jane's instruction then there is no contract and Jane does not have to pay anything; I don't think this is what you are asking but I include it for completeness. If it is understood that this arrangement continue week after week then either there is an ongoing contract or, more likely, a series of independent contracts. If there is an ongoing contract, then it can be renegotiated but it cannot be changed unilaterally by Bill. That is, he cannot unilaterally increase the price to $2. If there is a series of contracts then the terms of each of those contracts will be the same based on the course of dealing. Basically, the parties have accepted over a long period of time that the rate for a mow is $1 and Bill would have to get Jane to accept the revised rate before he mows the lawn. For your example, Jane owes Bill $1 but if she wants him back next week she will have to agree to Bill's rate.
Per GDPR Art 12(5), “any actions taken under Articles 15 to 22 and 34 shall be provided free of charge”. The right to rectification is Art 16 and reads in its entirety: The data subject shall have the right to obtain from the controller without undue delay the rectification of inaccurate personal data concerning him or her. Taking into account the purposes of the processing, the data subject shall have the right to have incomplete personal data completed, including by means of providing a supplementary statement. Thus, I think it would be invalid to charge a fee for an address change if that change was made in exercise of your data subject rights. If you didn't invoke this right, it's debatable whether charging a fee would be proper. On the one hand, they can charge whatever service they want (provided that this was part of the contract you entered). On the other hand, they have an obligation to assist you with your exercise of data subject rights. This includes recognising a data subject request even if you didn't explicitly invoke the specific GDPR article. For example, refusing a request for erasure just because you didn't invoke some magic GDPR words would be clearly noncompliant in my opinion. If the company offers multiple customer service options, charging for some of them may be all right. Typically, the lowest-cost solution for a company to deal with GDPR requests is to offer an online self-service option. An email to the data protection officer would typically also be free. Charging for phone support might be fine though. In an insurance context, there could also be a legitimate claim that updating your address is not a mere correction of your personal data, but a modification of the contract (depending on what you're insuring). Another possible counterpoint (which I think is not valid though) would be that the company never stored inaccurate data and therefore doesn't have to satisfy a rectification request.
This has very little legal effect. It means that someone forgot to update their annual registration and pay the fee and could be resolved in half an hour with a small late fee payment. It is a sign of slight sloppiness, but is only sometimes evidence of something more serious. For example, if a company moves to a new location without remembering to inform the Secretary of State, it might not get the annual report notice and thus fail to file. And, a company rarely has an occasion to double check that it is in good standing. Usually, the only legal consequence is that the company can't commence a lawsuit without bringing itself into good standing and that another company can steal its business name (if it can do so without violating a common law trademark arising from use of the name). It does not significantly change the rights of parties dealing with the company in terms of property ownership, contract rights, etc. This said, closer scrutiny than a company without that issue might be in order and the fact that you are checking at all means that there might have been other reasons apart from this fact to be concerned.
The price is not one of the terms and conditions of the CC-SA license. You may chose to attach a price to a derivative work (which you have the right to create under license section 3.b). But any person who receives the derivative work legitimately (from you or from someone who got it from you, directly or indirectly) must get it under the CC-SA license, and has the right to redistribute it, and may do so at no charge if that person so chooses. Also, you may not impose any copy protection or other technological measure that would prevent exercise of the reuser's rights. Whether selling a work that may be redistributed freely is good business is your decision.
Probably not “Air conditioning” is the process of changing the temperature and/or humidity of air. A “fan” is a device for moving air around. It’s almost certain the arbitrator would agree. However, the customer is unlikely to be entitled to a refund because there hasn’t been a “complete failure of consideration” - they contracted for an apartment with air conditioning, they got an apartment ergo Airbnb has provided some part of the consideration. They would be entitled to damages - perhaps the cost of hiring an air conditioner or if that’s not possible, a hotel room (which I realise may be more than the value of the letting but that’s how damages can work).
Dale has the right answer, but I'd like to elaborate on why it isn't lawful (as compared to why it would be unlawful). I know it doesn't work that way on line, but it's simpler to think of a credit card as a physical piece of plastic. The bank will have issued this to their customer. It will have a number and an expiry date. You have no way of knowing whether a replacement card has been issued. Even if one has, the customer has authorised you to charge a specific card - you do not have the customer's authorisation to charge a different card with a different expiry date. By guessing the expiry date, you would be making a representation to the bank that the customer has authorised you to charge that card (if it exists), when they have not.
