Confession is regarded as the strongest means of evidence, upon
which a judge is prompted to issue a particular verdict for
conviction.
Despite this, a confession given under duress or coercion, even
if it is factual, is not a valid confession and cannot legally be
relied upon. It is imperative that the confession, concerning the
accident in question, is clear and explicit, and is not subject to
interpretation.
Accordingly, a confession is considered invalid if it is the
result of invalid procedures, and there exists a causal link
between the invalid procedure and the confession (whether the
procedure was carried out prior to or simultaneous with the
confession). If however, the allegedly invalid procedure takes
place subsequent to, or independent of the confession, the
confession would be legally acceptable.
