Section 121(3A) Child Marriage: Custody Generally Inevitable Where a Person of Authority Conducts the Ceremony

A) Precedents and materials cited (and their influence)

This was the first section 121(3A) case to reach the Court of Appeal, so the decision is notable for proceeding without prior appellate authority on sentence for this amended offence. The court’s reasoning was therefore built primarily on:

• The general Sentencing Council guideline (no offence-specific guideline existed). The sentencing judge (and the Court of Appeal) treated the general guideline as the appropriate framework for assessing culpability, harm, and the custody threshold.
• The “FGM guideline” analogy (considered but not applied directly): the sentencing judge was invited to use the FGM guideline as an analogy but declined, and the Court of Appeal endorsed that approach because FGM involves immediate physical trauma and enduring consequences that do not map neatly onto all section 121(3A) scenarios.
• Marriage and Civil Partnership (Minimum Age) Act 2022 (in force 27 February 2023): the court treated Parliament’s removal of all exceptions (including parental consent) as a clear policy decision that child marriage requires firm deterrence and child-protection-oriented sentencing.
• Explanatory Notes to the Marriage and Civil Partnership (Minimum Age) Bill and the UN Committee on the Rights of the Child recommendations: used to explain the safeguarding rationale for the 18 minimum age and to underline the evidence base about adverse impacts—especially on girls.

The absence of prior case-law shaped the judgment’s most practically significant feature: the court articulated structured (but non-exhaustive) factors for assessing culpability and harm under section 121, effectively offering a proto-guideline for future sentencing exercises.

B) Legal reasoning

1. The statutory context: a broad offence aimed at safeguarding

The court emphasised that section 121, as amended, captures a wide spectrum—from forced overseas marriages involving coercion, deception, and violence, to domestic religious ceremonies involving willing older teenagers. That breadth required a principled sentencing approach that can differentiate between very different factual scenarios while remaining faithful to Parliament’s protective purpose.

2. A structured approach to culpability and harm (non-exhaustive factors)

To guide sentencing across the spectrum, the court endorsed (with credit to counsel) two lists of relevant factors. These lists are not exhaustive, but they are likely to be treated as a key starting point in future section 121(3A) cases:

Culpability factors (as identified by the court):

• Use of coercion, pressure, deception, threats of, or actual, violence
• Whether the offender is in a position of authority (e.g., parent, family elder, religious leader)
• Whether the offender knew or suspected the child’s age
• Whether conduct was one-off/spontaneous or deliberate/planned/repeated
• Whether conduct was open/transparent or secretive
• Steps taken to avoid detection/safeguarding/school/police/immigration controls
• Whether conduct involved taking or sending the child abroad
• Improper advantage (financial, sexual, immigration, “honour”, reputational, etc.)

Harm factors (as identified by the court):

• Whether a marriage ceremony took place
• The age of the child
• Whether removed from education
• Physical/psychological harm (fear, trauma, isolation, loss of autonomy)
• Increased risk of unwanted sexual activity or sexual exploitation
• Impact on future prospects and life chances
• Whether consummation or cohabitation followed
• Whether the child remained under family/community pressure
• Whether there was more than one child/victim

Applying those factors, the court agreed with the sentencing judge that culpability was “medium to low” and harm “low”. The children approached the mosque; there was no coercion or pressure; and the sentencing judge found no immediate harm. However, culpability was not “low” because the applicant was a religious leader responsible for conducting marriages and should have been aware of: (i) the February 2023 legal change; and (ii) even under the previous law, the need for parental/guardian consent for 16–17 year-olds.

3. The custody threshold: why it was crossed despite low harm and strong mitigation

The decisive reasoning concerned the custody threshold. The court accepted the substantial mitigation: good character, early guilty plea, admissions, low risk of reoffending, and immediate safeguarding changes at the mosque. But it held that the offence nevertheless carried “significant seriousness” because Parliament’s aim was to protect children even from their own (or their parents’) decisions about marriage, reflecting evidence-based harms associated with child marriage.

The court then articulated a strong general proposition for future cases: facilitation of under-18 marriage is “overwhelmingly likely” to attract custody. It contemplated a narrow category of “margin” cases—where involvement is fleeting or incidental, by someone with little influence—where a community sentence might be appropriate. The applicant’s conduct did not fall into that category because he was a figure of authority who conducted and completed the ceremony.

4. Religion, age of consent, and compliance with the law

The court acknowledged a practical tension: the age of consent is 16, while many religions prohibit sex outside marriage. Nonetheless, it held that a desire to prevent “sin” cannot justify non-compliance with the statutory scheme protecting children from marriage under 18. This is an important statement for cases involving religious-only unions (including where the parties may view the ceremony as morally obligatory even if not a civil marriage).

C) Impact

• First appellate guidance on section 121(3A) sentence: the decision will be treated as the leading starting point until a Sentencing Council offence-specific guideline emerges.
• Proto-guideline factors: the culpability and harm factor lists provide a structured checklist that will likely be adopted in sentencing remarks, prosecution submissions, and defence mitigation.
• Custody as the norm, especially for authority figures: the court’s language (“overwhelmingly likely”; “inevitable” for authority figures who conduct the ceremony) meaningfully raises the bar for arguments that a fine or community order is sufficient, even where the child is a willing participant.
• Safeguarding-driven deterrence: general deterrence is explicitly endorsed, signalling that sentence is not only about individual harm proved in a specific case but also about reinforcing the protective purpose of the minimum-age reform.
• Operational consequences for religious institutions: the judgment implicitly incentivises robust age-verification and safeguarding processes for religious marriage ceremonies, because “ignorance of the law” by those responsible for conducting marriages will carry limited weight.
