Experimenting without consent

what are the legal issues involved with experimenting on a subject without there consent..i.e stipulations, exceptions, rights, etc.

admin can move this to the proper category...didn't know which one to put it in.

Define "experimenting". Trying on clothes of different colors? Going to a wine tasting?

Define "subject"--a dog? a cat? a car?

Whose stipulations?

Bottom line: If the "subject" is a person and you do ANYTHING against their will (anything that is protected by the Constitution <<anything against the law>>) you are in violation of the law. Period. There ARE no stipulations or exceptions you can claim that over rule a persons personal right to say NO to you. Why in the world would you think otherwise?

If you would like to offer a more precise question, you may get a more precise answer.

ok say one had people, whom he has no idea who they are, running electrical currents through various parts of his body, among many other things. never agreeing to have this experiment done on him. plus i've read there were cases where experimenting without consent was allowed because of community consultation and public disclosure; just wondering what that means..includes?
