Study notes for United States v. Brewer: professor notes, cold call prep, exam angles, and memory aids.

The prosecution must establish a complete chain of custody for evidence to be admissible in court.
Professor Notes

In United States v. Brewer, the Ninth Circuit emphasized the critical nature of maintaining an unbroken chain of custody for evidence in criminal trials. The court raised concerns about the integrity of evidence when there are gaps in documentation and handling. This case serves as a fundamental example for law students of the stringent requirements that must be satisfied to ensure that physical evidence remains credible and admissible in court.

The ruling underscores not only the importance of procedural safeguards in the collection and presentation of evidence but also highlights the crucial role these protocols play in protecting the rights of defendants. In this case, Brewer's defense effectively leveraged the prosecution’s failure to prove a proper chain of custody in order to have the drug evidence excluded, illustrating how procedural missteps can lead to the reversal of convictions.
