Right to Biological Parentage Trumps Social-Psychological Ties in Annulment of Legal Paternity

The appellate court upheld the lower court's decision to retroactively annul the legal parent-child relationship between the plaintiff and the first defendant (a child born in 2002), reasoning that the child's fundamental right to know their biological parentage supersedes maintaining concealed family situations, in line with evolving national and international legal principles emphasizing the "material truth" of parentage over merely establishing a provider through social-psychological ties. The court found that the child's interest in knowing their true biological origins was paramount, even over the established social-psychological connection with the legal father, especially given the child's young age and lack of current contact with the plaintiff.
