Fourth Amendment to the United States Constitution
Limitations

In Arizona v. Evans (1995) and Herring v. United States (2009), the Court ruled that the exclusionary rule does not apply to evidence found due to negligence regarding a government database, as long as the arresting police officer relied on that database in "good faith" and the negligence was not pervasive. In Davis v. United States (2011), the Court ruled that the exclusionary rule does not apply to a Fourth Amendment violation resulting from a reasonable reliance on binding appellate precedent. In Utah v. Strieff (2016), the Court ruled that evidence obtained from an unlawful police stop would not be excluded from court when the link between the stop and the evidence's discovery was "attenuated" by the discovery of an outstanding warrant during the stop.
