Laws about being asked to pay for something somebody else organised without your consent?
There's this one girl at my school who keeps organising gifts for all our teachers and goes on to buy them. The thing is, she then expects all of us to pitch in and cover the cost. Honestly, I can't afford to give $10 for every teacher I have. I don't want to take legal action or anything, I just want to know if there are any legitimate laws I can cite to get her off my case.
You are under no legal obligation to participate in this organized brown nosing. When she comes around to collect money, tell her that you did not agree to pay for anything, can't afford to, and that you're not obligated. There isn't a law that supports this. It's common sense.
You are under no obligation whatsoever to contribute. And, she has no right whatsoever to harass you to contribute. She took it upon herself to buy the item. She gets only what people are "willing" to contribute. Tell her your allowance does not cover spending that much money and if she does not stop harassing you about it, you will report her to the principal and to the police.
This is more of an etiquette and social question than a legal one- all you have to do is say no. She went and bought somebody else a gift without checking this out with you, and you quite reasonably don't want to pay for them. That's simple common sense and bad manners on her part.
I don't know if there's any specific laws on this- there hasn't really ever been a need to make it illegal to ask someone for money for something that isn't related to you. I suppose if you had to come up with a law to throw at her, you could use the Consumer Protection Act, which does make it illegal to pay for "unsolicited goods" - e.g. if you send some goods to someone and then demand payment, that's actually a crime under US law, and that's probably the closest you'd get legally.
That being said, if you need to cite federal laws with this situation, rather than to simply tell her that what she's doing just isn't cool, that's itself a problem.
Look up the word "no" in the dictionary. Get a good grasp on what it means. Then use it.
