Overview
- The Court of Appeal ruled that current evidence cannot identify which identical twin fathered the child known as P.
- Standard DNA tests confirmed one twin is the biological father but cannot distinguish between the brothers, leaving a 50% chance the registered twin is correct.
- Judge Madeleine Reardon previously found both men had sex with the mother within a four‑day window during the month of conception, making either man equally likely to be the father.
- The panel said the twin on the birth certificate was not entitled to be registered as father, so his parental responsibility ceases for now as the case continues.
- Judges noted future genomic techniques might separate the twins’ DNA at very high cost, reported around £90,000, yet results may still not be definitive under today’s science.
