Facts

Several criminal matters involving different accused persons were placed before an eleven-judge Bench.
In the connected cases, investigating authorities had obtained or sought to use:
specimen handwriting;
specimen signatures;
thumb impressions;
palm impressions;
foot impressions;
identification measurements.
In one matter, a disputed handwritten document was compared with specimen writing obtained from the accused.
The accused argued that compelling them to provide such material violated Article 20(3).
Article 20(3) provides that no person accused of an offence shall be compelled to be a witness against himself.
They contended that:
specimen writing and fingerprints were evidence;
compelling production made the accused a witness against himself;
anything personally supplied by the accused was protected.
Questions also arose concerning information supplied by an accused in police custody which led to discovery under Section 27.
The Court reconsidered the broad language used in the earlier decision of M.P. Sharma v. Satish Chandra.

Whether giving specimen handwriting, signatures or fingerprints amounts to being “a witness” against oneself.
What is the distinction between testimonial evidence and physical evidence?
Whether Section 27 discovery information violates Article 20(3).

Article 20(3) applies when:
the person is formally accused of an offence;
there is compulsion;
the compulsion requires the accused to be a witness against himself.
“To be a witness” principally means imparting personal knowledge through testimonial or communicative acts.
The privilege protects compelled communication such as:
oral answers;
written statements conveying knowledge;
confessions;
explanations of facts.
It does not ordinarily protect compulsory production of physical characteristics such as:
fingerprints;
palm impressions;
footprints;
specimen handwriting;
specimen signatures;
photographs;
bodily measurements.
Such material is used for comparison and does not, by itself, communicate the accused’s personal knowledge of the offence.
Section 27 does not automatically violate Article 20(3).
A voluntarily supplied discovery statement may be admitted.
A statement actually obtained through unconstitutional compulsion cannot receive protection merely because it led to discovery.

The Court distinguished a statement conveying knowledge from a physical characteristic used for identification.
When an accused writes a specimen phrase:
he is not being asked to describe the crime;
he does not communicate whether he committed the offence;
the content of the words is ordinarily irrelevant.
The prosecution uses only physical features of the handwriting, such as:
formation;
slant;
pressure;
individual style.
Similarly, fingerprints exist independently of the accused’s will.
Their evidentiary value comes from comparison with marks found elsewhere.
The accused is therefore a source of physical evidence but not a testimonial witness.
The Court accepted that every act performed by an accused may ultimately assist the prosecution.
Article 20(3), however, does not prohibit all compelled assistance.
It prohibits compelled testimonial self-incrimination.
The distinction prevents the privilege from covering:
identification parades;
medical observation;
fingerprints;
bodily measurements.
On Section 27, the Court stated that custody does not itself prove compulsion.
Whether information was voluntarily given or extracted by pressure is a factual question.
If the information is voluntary, the discovery portion may be admitted.
If it is compelled in a constitutionally prohibited manner, Article 20(3) applies.
The Court narrowed the broader interpretation of testimonial compulsion suggested in M.P. Sharma.

The Supreme Court held that compelling an accused to provide:
specimen handwriting;
signatures;
fingerprints;
palm or foot impressions, does not ordinarily violate Article 20(3).
These are physical identification materials rather than testimonial communications.
Section 27 was also held constitutionally valid, provided the information was not obtained through prohibited compulsion.
The decision established the fundamental distinction between:
compelled personal testimony;
compulsory physical or identifying evidence.
