In the midst of the discussion over marriage equality these days, let us ask this question: Should three people be allowed to marry each other? After all, they're all grown ups and what business does society have in regulating what they do in private?
That's the controversy surrounding the case of a three-person civil union in Brazil:
A notary in the Brazilian state of Sao Paulo has sparked controversy by accepting a civil union among three people.
Public Notary Claudia do Nascimento Domingues has said the man and two women should be entitled to family rights. She says there is nothing in law to prevent such an arrangement.
But the move has angered some religious groups, while one lawyer described it as "absurd and totally illegal".
The three individuals, who have declined to speak to the press, have lived in Rio de Janeiro together for three years and share bills and other expenses.
