noun
A test originally formulated to evaluate whether a defendantÂ’s constitutional
rights were violated in the eliciting of a confession. It concentrates on
looking at all the circumstances surrounding the alleged violation rather than
only one or two aspects, as had been the case before. It had been used as a
measure of whether a defendantÂ’s privilege against self incrimination had been
violated, but since the advent of the Miranda
rule (1966), that use has become obsolete. It is now used to determine
whether a defendant consented to a warrantless search, and whether probable
cause exists for the issuing of a search warrant.
