No forensic evidence. No third-party witness. Conviction upheld.

The father, the nine-year-old, and the testimony that held

Stephen was the father of a nine-year-old girl. On the evening of 9 August 2013, when her mother was at work, he sexually assaulted his daughter by penetrating her mouth with his penis. He then threatened to kill her if she spoke. When the mother returned home that night, the child was visibly upset. She disclosed the assault. The next morning, the mother walked into Venjaramoodu Police Station in Thiruvananthapuram and lodged a complaint. That complaint set in motion a legal journey that would end, sixteen years later, in a Division Bench of the High Court of Kerala at Ernakulam — with the father's life sentence upheld, and a crucial legal standard reaffirmed for every trial court in the country.

What the child told the court

The trial was held before the Additional District Court & Sessions Court (Atrocities & Sexual Violence Against Women & Children), Thiruvananthapuram. The prosecution examined the child as PW2. She was the sole eyewitness to the assault. There was no forensic evidence, no third-party witness, no CCTV footage. The entire case rested on her testimony.

And she testified. In categoric terms. She described what her father did. She described the threat. She described telling her mother. Her account was consistent with the FIR that her mother had lodged the very next day. Under cross-examination, the defence tried to shake her. Nothing was elicited that cast doubt on her veracity. The trial court believed her. On 26 July 2016, Stephen was convicted under Section 5(n) read with Section 6 of the Protection of Children from Sexual Offences Act, 2012 — aggravated penetrative sexual assault by a relative — and sentenced to life imprisonment with a fine. He was also convicted under Section 9(n) read with Section 10 POCSO (aggravated sexual assault, five years rigorous imprisonment) and Section 506 Part 2 of the Indian Penal Code (criminal intimidation with threat of death, one year rigorous imprisonment).

The appeal: what the father argued

Stephen appealed to the High Court of Kerala. His counsel raised two principal arguments. First, that the child's testimony was unreliable — that a conviction could not rest solely on her word without corroboration. Second, that even if the conviction stood, the life sentence was disproportionate. For the sentencing argument, the appellant's counsel cited Narayanan v. State of Kerala (2021 KHC 564), which, according to the submission, had held that a sentence in a similar case was excessive.

The State of Kerala, through the Public Prosecutor, defended the conviction and sentence. The victim's testimony, the State argued, was of sterling quality. The father-daughter relationship made the offence particularly grave. The life sentence was neither harsh nor disproportionate.

The witness rule the Supreme Court applied

The Division Bench — Justice P.B. Suresh Kumar (author) and Justice Johnson John (concurring) — turned first to the law on sole testimony. They drew from Rai Sandeep v. State (NCT of Delhi), (2012) 8 SCC 21, which defined the "sterling witness" standard. A sterling witness, the Supreme Court held, is one whose version is unassailable, natural, and consistent from the initial statement to the court testimony; who withstands cross-examination without giving room for doubt; and whose account correlates with all supporting materials.

The High Court applied that standard to the nine-year-old's evidence. It found that her testimony met every element. She was consistent from the FIR to the witness box. She was not shaken in cross-examination. Her prompt disclosure to her mother — and the mother's immediate action — provided corroboration. The Bench observed that the child's evidence was of "very high quality and calibre." The conviction could, and did, rest on her word alone.

THE PLAY: When a child victim's testimony is consistent from first disclosure to court deposition, withstands cross-examination without doubt, and is corroborated by prompt complaint, it meets the sterling witness standard — and a conviction can stand on that testimony alone, without forensic or third-party corroboration.

Why the life sentence stayed

On the sentencing question, the High Court was blunt. The accused was the biological father of a nine-year-old child. The offence was aggravated penetrative sexual assault under Section 5(n) POCSO — specifically because the perpetrator was a relative. The minimum sentence under Section 6 is rigorous imprisonment for twenty years, extendable to life. The trial court had imposed life imprisonment. The High Court found nothing disproportionate about it. The Bench distinguished Narayanan v. State of Kerala on its facts, without elaborating. The sentence was affirmed.

There was one loose thread. The accused had also been convicted under Section 9(n) read with Section 10 POCSO for the same act — aggravated sexual assault. The High Court noted that the accused had already undergone that sentence (five years RI) by the time of the appeal. It chose not to examine whether a conviction under both provisions for the same conduct was sustainable. That question — whether dual conviction under Sections 5(n)/6 and 9(n)/10 for the same act constitutes impermissible double conviction — was left open. It may well be raised in a future case.

What this means for practitioners

For advocates handling POCSO appeals, this judgment is a clean restatement of the sterling witness standard in the context of child testimony. The key takeaway is procedural: the court examined the victim's evidence not in isolation, but against the framework of Rai Sandeep. The consistency between the FIR, the deposition, and the cross-examination was the decisive factor. If you are defending a POCSO conviction based on sole testimony, your attack must target that consistency — not merely argue that corroboration is required.

For prosecutors, the judgment reinforces that a child victim's testimony, if it meets the sterling standard, is sufficient to sustain a life sentence. The promptness of the complaint — the mother went to the police the very next day — was treated as corroborative. Delay in disclosure, or inconsistency between versions, would be the vulnerabilities to watch for.

For founders and CFOs who may serve on company boards or manage organisations that deal with children, the judgment is a reminder that the legal system treats child sexual abuse by a relative with the utmost severity. The POCSO Act mandates a minimum of twenty years for aggravated penetrative sexual assault. Life imprisonment is not an outlier — it is the expected response when the perpetrator is a parent or guardian.

The bottom line

When a nine-year-old victim of sexual assault by her father testifies consistently, promptly, and without being shaken in cross-examination, her word alone is enough to convict — and a life sentence is not disproportionate.
