Under what condition can a confession be lost in court?

A confession can be lost in court if it was made involuntarily because the legal principle behind this is rooted in the protection against self-incrimination and the right to fair treatment under the law. When a confession is involuntary, it typically means that it was obtained through coercion, force, threats, or deceptive practices, which compromise its reliability. Courts prioritize the integrity of the legal process and the rights of the defendant; therefore, any confession that does not stem from free will is deemed inadmissible, as it may not accurately reflect the truth and is considered a violation of constitutional rights.

The other conditions mentioned, such as whether the confession was made in front of a witness, recorded, or not signed, do not impact the admissibility of the confession in court in the same significant way as involuntariness. A confession can still be valid and admissible even if it is not witnessed, not recorded, or not formally signed, provided it was made willingly and with the necessary understanding of its implications.
