Voluntary Consent and Legal Status - While voluntary consent is a key requirement, even if an accused voluntarily undergoes narco-analysis, the resulting statements are not legally admissible.

Legal Position on Deception Detection Tests - Tests like polygraph, brain mapping, and narco-analysis are considered investigatory tools, but their scientific reliability remains under debate.
