There is no legal context lol. Its illegal for us to buy, its legal for them to sell. By law thats it. But if no buyer then there is no seller ...:/. Its not rocket science. Races/colors/weight/age has nothing to do with it.
I don't understand the legal context either. Hypothetical situation #1: an escort shows up at a client's hotel room. Upon the client opening the door, the escort observes that he is an Indian client, a group she doesn't service. She informs the client, bluntly, "sorry, but I do not service Indian clients." She then walks out, leaving the client holding his boner.
Can he sue for illegal discrimination? Of course not, because he was engaged in an illegal activity. There is no discrimination. Under the law, the transaction is "void ab initio"- void from inception due to illegality. Therefore, no illegal discrimination could occur. At most it was non--actionable prejudice against an ethnicity.
Hypothetical situation #2: an escort shows up at client's hotel room. She has advertised to the client her rate is $300 per hour. The client hands the escort $300. She says to the client, "thank you. I just need to go downstairs and pay the driver." She doesn't come back.
Let's assume the client knows the escort's full name and address. Can he bring a small claims lawsuit against her, for breach of contract?
Answer: No. This lawsuit would be dismissed by any Judge in any court of competent jurisdiction in the USA or Canada. Anyone who has studied law and taken a course in contracts knows that the consideration for a contract cannot be meretricious or for services not allowed under the law. There is no contract and the $300 may not be returned, nor the contract enforced, on a breach of contract theory.
Can the client pursue a misdemeanor theft charge with the police?
On these same facts in the USA, under no circumstances as you would be admitting to a misdemeanor in order to pursue a misdemeanor charge which, in all likelihood, would not be charged. More likely is that the client would be charged if he foolishly pursued this with the police.
On these same facts in Montreal, I suspect the same analysis would apply.
So bringing up laws and legal rights is all bullshit because none of it is enforceable in Court. If it's not enforceable in Court it's not only bullshit, but bullshit in its purest and most unadulterated form. It's Super Bullshit.
By the way, I have an actual law degree and I have passed the bar in 3 US jurisdictions. You would be surprised that questions like the ones I posted above make their way onto law school exams (contracts and criminal law) and in some form on bar exams as well. Law school professors try to trick you into allowing yourself to think like a civilian instead of a lawyer. That's what separates the lawyers from the civilians in the tested group.
