sentences:  Prophylactic rule
  
  A prophylactic rule is a judicially crafted rule that overprotects a constitutional right, and gives more protection than such right might abstractly seem to require on its face, in order to safeguard that constitutional right or improve detection of violations of that right.An example is the case of "Miranda v. Arizona" which adopted a prophylactic rule ("Miranda warnings") to protect the Fifth Amendment right against self-incrimination.
