Final answer:
A defendant requires standing to challenge the admissibility of evidence under the Fourth Amendment, which is essential for invoking the exclusionary rule that prevents evidence obtained from an illegal search or seizure from being used in court.
Explanation:
A defendant must have standing to legally challenge the admissibility of evidence under the Fourth Amendment. The term 'standing' refers to the requirement that an individual has a sufficient connection to and harm from the law or action challenged to support that person's participation in the case. If a defendant does not have standing, they cannot challenge the evidence supposedly obtained in violation of their Fourth Amendment rights.
The Fourth Amendment largely pertains to investigations conducted before someone has been charged with a crime and protects individuals from unreasonable searches and seizures. The exclusionary rule pertaining to the Fourth Amendment prevents evidence from an illegal search or seizure from being introduced against a defendant in court. Therefore, standing is essential for a defendant who wishes to invoke this rule.
