The federal due process standard governing the admissibility of eyewitness evidence is set forth in the U.S. Supreme Court case of "Manson v. Brathwaite". Under the federal standard, if an identification procedure is shown to be unnecessarily suggestive, the court must consider whether certain independent indicia of reliability are present, and if so, weigh those factors against the corrupting effect of the flawed police procedure. Within that framework, the court should determine whether, under the totality of the circumstances, the identification appears to be reliable. If not, the identification evidence must be excluded from evidence under controlling federal precedent.
