What is the primary purpose of the exclusion of evidence in legal contexts?

The primary purpose of excluding evidence in legal contexts is to protect individual rights. This principle is grounded in the idea that certain types of evidence may infringe upon a defendant's right to a fair trial or violate legal standards that safeguard personal freedoms. For example, evidence obtained in violation of constitutional rights, such as through unlawful searches or coercive interrogations, is typically excluded to ensure that the judicial process respects these rights.

Exclusion serves as a mechanism to uphold the integrity of the legal system, ensuring that only reliable and justly obtained evidence is presented in court. This is essential for maintaining public confidence in the criminal justice system, as it emphasizes the balance between the pursuit of truth and the protection of individual liberties.

While reducing the length of trials, increasing the number of witnesses, or eliminating jury bias can be positive outcomes, they are secondary to the overarching goal of upholding rights and sustaining the fairness of proceedings.
