Answer:
informed consent
Explanation:
According to my research on experiment legal procedures, I can say that based on the information provided within the question all studies involving human subjects must include informed consent. This term is defined as permission granted in full knowledge of the possible consequences. If a researcher does not have this, then the researcher cannot legally use the subject for his studies, since in the eyes of the law it may be considered torture or kidnapping since you do not have proof of the subjects consent.
