An abortion under this subsection may only be performed if the above-mentioned medical judgment of the physician who is to perform the abortion is first certified by the physician in writing, setting forth in detail the facts upon which the physician relies in making this judgment and if this judgment has been concurred in by two other licensed physicians who have examined the patient. The foregoing certification and concurrence is not required in the case of an emergency when the abortion is necessary to preserve the life of the patient.
