The Uruguay Senate (Camara de Senadores) on Wednesday agreed to postpone a vote on a gay marriage bill.

According to the AFP, the Senate, which is currently in parliamentary recess, held a special session to discuss a dozen bills, including one which states that “marriage is the permanent union between two persons of the same or opposite sex.”

The “Marriage Equality Law” seeks to modify some 20 articles of the Civil Code, including whose surname goes first when children are named.

Opponents asked for the bill's vote to be postponed until the Senate's first meeting in April to allow more time to study the proposal. The request received unanimous approval.

The bill has already received an initial nod in the Senate and it cleared the nation's lower house earlier this month. President Jose Mujica has said he'll sign the bill into law.

Uruguay currently recognizes gay couples with civil unions. After a couple has lived in a “stable relationship” for 5 years, they may petition the government for the recognition.

If the marriage law is approved, Uruguay would become only the second South American country after Argentina to legalize marriage equality.
