informed consent n. agreement to do something or to allow something to happen only after all the relevant facts are known. In contracts, an agreement may be reached only if there has been full disclosure by both parties of everything each party knows which is significant to the agreement. A patient's consent to a medical procedure must be based on his/her having been told all the possible consequences, except in emergency cases when such consent cannot be obtained. A physician or dentist who does not tell all the possible bad news as well as the good, operates at his/her peril of a lawsuit if anything goes wrong. In criminal law, a person accused or even suspected of a crime cannot give up his/her legal rights such as remaining silent or having an attorney, unless he/she has been fully informed of his/her rights.
