Doctrine of Rectification
Case Details:
Re Human Fertilisation and Embryology Act 2008 (Case G) [2016] EWHC 729 (Fam)
Background
The case involved a same-sex couple, X and Y, who underwent IVF treatment at a licensed clinic. Y, the gestational mother, gave birth to twins conceived using X’s biological eggs. Under the Human Fertilisation and Embryology Act (HFEA) 2008, for X to be recognized as a legal parent, specific forms must be signed: the gestational mother must sign Form WP (consenting to her partner being a parent), and the partner must sign Form PP (consenting to be a parent).
Due to administrative errors by the clinic, the partners accidentally swapped roles: Y signed Form PP and X signed Form WP. Additionally, Y was in a civil partnership with another woman (CP), though they were separated. Under Section 42 of the HFEA 2008, a civil partner is presumed to be the legal parent unless it is shown they did not consent to the treatment.
Contentions of the Parties
- The Applicant (X): Supported by Y and the children’s guardian, X sought a declaration of parentage under Section 55A of the Family Law Act 1986. The primary legal question was whether the court could “fix” the swapped forms through legal construction (interpreting the existing words) or rectification (formally amending the documents).
- The Civil Partner (CP): Provided a witness statement clarifying that she had no involvement in the treatment plans, did not consent to be a legal parent, and fully supported X’s application.
- The Clinic: Acknowledged the error occurred but initially offered only a £1,000 “ex gratia” payment as a final settlement, a gesture the parents found “insulting” and “crass”.
The Judge’s Decision
Sir James Munby, President of the Family Division, granted the declaration of parentage for X. He ruled that the swapped forms should be corrected through the doctrine of rectification. Furthermore, he found that the statutory presumption of the civil partner’s parentage had been successfully rebutted.
Reasoning of the Judgment
The court’s reasoning focused on the equitable power to correct obvious mistakes and the factual nature of consent:
- Doctrine of Rectification: Applying the Supreme Court precedent in Marley v Rawlings, the judge held that the court has the power to rectify documents where a clear mistake has been made. He ordered the wholesale transposition of the text of the two forms, effectively swapping the printed content so the signatures matched the correct statutory requirements.
- Rebutting the Presumption of Consent: The judge clarified that Section 42 creates a rebuttable presumption of parentage for a civil partner, not an absolute rule. Because CP explicitly stated she did not consent, and there was no evidence to the contrary, the “obstacle” of the civil partnership was removed.
- Intent and Good Faith: The judge found as a fact that both X and Y acted in complete good faith, always intended for X to be a legal parent, and were only alerted to the error by the clinic much later.
- Criticism of Administrative Failure: The President was highly critical of the clinic’s “incompetence” and the “insensitive” response of their solicitors, emphasizing that parentage is a matter of “transcendental importance” that should not be jeopardized by clerical errors.
Conclusion
Re Case G reinforces the principle that substance and parental intent take precedence over administrative form in fertility law. By utilizing the power of rectification, the court ensured that a biological mother was not deprived of her legal status as a parent simply because a clinic provided the wrong paperwork to sign.
