Mexico federal prosecutors have filed an appeal with the Mexican Supreme Court in an effort to void Mexico City's marriage equality law before it goes into effect in March:
"The federal Attorney General's Office said in a statement that it believes the law 'violates the principle of legality, because it strays from the constitutional principle of protecting the family.'
It cited an article in Mexico's constitution that suggests – but does not state – that the framers envisioned families constituted by men, women and children. The article states: 'Men and women are equal before the law. This protects the organization and development of the family.'"
They said it also "strays from the responsibility of the government to place a priority on
safeguarding the interests of children."
The law was passed in December by a vote of 39-20.
