A Michigan mother whose twins were conceived using in-vitro technology after their father died is asking the state Supreme Court to allow the children to get death benefits and inheritance rights.
Pam and Jeff Mattison had a daughter using in-vitro fertilization, and wanted more children.
But Jeff Mattison was ill, and died just before the procedure was performed again.
Pam Mattison had a twin boy and girl nine months after her husband died. She applied for Social Security benefits for the twins, but was denied.
