Which witness fails the competence test in section 124 of the Bharatiya Sakshya Adhiniyam, 2023?

Inability to speak does not make a person incompetent. Section 125 permits intelligible communication such as writing, subject to its procedural requirements.

Deafness alone does not disqualify a person who can understand questions and give rational answers.

A child can testify if the court finds they can understand the questions and respond rationally.

The statutory competence test requires the ability to understand questions and give rational answers. Failure to understand prevents competent testimony.
