Change of sex on birth certificate — sufficiency of evidence — “Michael” v Registrar-General of Births, Deaths and Marriages (2008) 27 FRNZ 58 — DAC v Registrar-General of Births, Deaths and Marriages [2013] NZFC 1998 — Crowley v Registrar-General of Births, Deaths and Marriages [2015] NZFC 3401 — Births, Deaths, Marriages and Relationships Registration Act 1995, s 28. The applicant applied to change his sex from female to male on his birth certificate. Under s 28(3)(c)(i) the Court must be satisfied on the basis of medical evidence that the applicant: has assumed the gender identity sought to be recorded on the birth certificate; has undergone medical treatment "as is usually regarded by medical experts as desirable" to conform with that gender identity; will, as a result of medical treatment undertaken, maintain that gender identity in the future. The Judge determined that the applicant had provided sufficient expert evidence for the purposes of s 28(3)(c)(i). It was noted that while the case of "Michael" required affidavit evidence from health professionals, in subsequent cases courts have been willing to accept reports and letters from professionals without requiring sworn affidavits or appearances in person. The result was that the application was set down for a formal proof hearing, and evidence could be given from Australia where the applicant was living via video link.
