Cases considering section 6 21

R v Thomas Lunn

[2026] EWCA Crim 934 · 7 July 2026

The court treated the assault by penetration as additional criminality capable of aggravating the lead count or being reflected through totality, and considered an upward adjustment of about one year appropriate (see paras [22]; [24]).

BDZ v R (Indictment misstating age of child victim of sexual offences)

[2026] EWCA Crim 10 · 16 January 2026

The court treated the under-13 element as requiring proof of the victim’s age and contrasted it with the general penetration offence. That distinction explained why the date error affected the analysis differently across the counts (see paras [12], [23]).

R v Clive Lloyd

[2023] EWCA Crim 1038 · 30 August 2023

The section 6 category 2A guideline comparator, with an 11-year starting point, was treated as a reference requiring adjustment for historic offending rather than a mechanically determinative sentence. (see paras [14], [16], [20])

Explanatory note

15.Section 6 makes it an offence for a person intentionally to penetrate sexually the vagina or anus of a child under the age of 13 with a part of his body, such as a finger, or with anything else, such as bottle or other object. The penetration must be sexual, as defined in section 78. Whether or not the child consented to the act is irrelevant.
