Key takeaways

  • Manson v. Brathwaite belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Manson v. Brathwaite to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Manson v. Brathwaite from memory before moving on to harder problems.

Reference excerpt

Manson v. Brathwaite, 432 U.S. 98 (1977) was a case decided by the Supreme Court of the United States in 1977. The decision touched on the exclusionary rule in state criminal proceedings. The Supreme Court held that the identification procedures used against Brathwaite did not violate the Constitution of the United States.

Background On May 5, 1970, Jimmy Glover of the Connecticut State Police went to an apartment building in Hartford with an informant, Henry Brown. The two had planned to buy drugs from "Dickie Boy" Cicero. They completed the purchase and, in doing so, Glover saw the seller's face through the apartment doorway. The pair left, and Glover went back to his station, where he described the seller to two other officers, D'Onofrio and Gaffey. On hearing the description, D'Onofrio believed that the description matched Brathwaite. D'Onofrio sourced Brathwaite's picture from the police records and left it at Glover's office. Glover then viewed the picture alone and positively identified Brathwaite as the person that had sold him the drugs. Brathwaite was arrested on July 27, 1970. At his trial, the picture that Glover had used to make the positive identification was admitted into evidence without objection. The prosecution did not explain why the police did not use a photographic lineup to make the identification. Brathwaite testified in his own defense that he had been sick and stuck in his own apartment on May 5. His wife and doctor corroborated this testimony. Indeed, Brathwaite had surgery for a herniated disc. The jury found Brathwaite guilty, and he was sentenced to 6–9 years in prison. His conviction was affirmed by the Connecticut Supreme Court in 1973. Brathwaite sought and did not receive federal habeas corpus relief in the United States District Court for the District of Connecticut. He appealed the decision to the United States Court of Appeals for the Second Circuit which reversed, holding that the photograph should have been excluded. The Supreme Court granted certiorari in 1976 (425 U.S. 957).

Decision In a 7–2 decision, the Supreme Court reversed the decision of the Second Circuit. Justice Harry Blackmun wrote the majority and reasoned that the law should strive to balance evidentiary reliability, deterrence of overreaching by the police, and the efficiency of the justice system. In balancing these three, he placed emphasis on the importance of reliable evidence in criminal proceedings. As such, the majority ruled that the appropriate factors to consider were those set out in Neil v. Biggers:"These include the opportunity of the witness to view the criminal at the time of the crime, the witness' degree of attention, the accuracy of his prior description of the criminal, the level of certainty demonstrated at the confrontation, and the time between the crime and the confrontation. Against these factors is to be weighed the corrupting effect of the suggestive identification itself." – Justice Blackmun, Manson v. Brathwaite 432 U.S. 98, 114 (1977).Applying the factors, the Court determined that the probative value of the evidence likely outweighed any prejudicial effect from its admission. The majority found that there was no "substantial likelihood of irreparable misidentification."

Aftermath The Brathwaite test has been criticized as being out of step with scientific research into eyewitness reliability.

Worked examples

Example 1 — a first encounter with Manson v. Brathwaite

Start with the simplest possible case. Write down what Manson v. Brathwaite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Manson v. Brathwaite before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Manson v. Brathwaite ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Manson v. Brathwaite

In research
Manson v. Brathwaite appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Manson v. Brathwaite in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Manson v. Brathwaite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Evidence law, Eyewitness, United States Fourteenth Amendment case law, so understanding it makes those chapters shorter.
In everyday life
Look for Manson v. Brathwaite outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
