Sometimes you call a spade a spade

Assuming the GP was for embargoed cc, aside from what has already been mentioned, an illegal contract (e.g. agreement to purchase illegal goods) is unenforceable. Therefore, the agreement itself is likely null and void. I'm not saying that he couldn't be criminally liable for fraud or theft (I don't practice criminal law), but any action would likely open up a can of worms that would be detrimental to the community as a whole. Caveat Emptor (buyer beware)! Some people (even friends and family) just suck!
