Which condition can render a confession inadmissible in court?

A confession can be rendered inadmissible in court if it results from an illegal search and seizure. The principle behind this is rooted in the protection against unreasonable searches and the right to due process under the law. When evidence, including confessions, is obtained through means that violate a person's constitutional rights—such as obtaining it during an illegal search—this evidence may be deemed tainted and therefore inadmissible. This ensures that law enforcement agencies adhere to legal protocols, protecting individuals from unlawful actions that compromise their rights.

In contrast, a recorded confession or one made voluntarily does not typically disqualify it from being admissible. The presence of a witness during the confession does not inherently affect its admissibility either unless the witness can provide evidence of coercion or manipulation during the confession process.
