 The person has the right to refuse to give consent, and except in limited cases may revoke consent at any point during the search.In addition, the prosecution in any trial using the search results as evidence is required to prove that the consent was voluntary and not a result of coercion.In contrast to Miranda rights, officers conducting a consent search are not required to warn people of their right to withhold consent in order for consent to be valid, as determined by the U.S. Supreme Court in "Schneckloth v. Bustamonte".
