Spain’s Constitutional Court is expected to rule on an appeal against the country’s equal marriage law, seven years after the legislation was approved.

The conservative Popular Party filed the appeal in 2005, arguing that marriage in the Spanish constitution meant the union of a man and a woman.

According to the Associated Press, a court spokesman said it would meet later on Tuesday to study the appeal and is expected to vote.

Euro Weekly News is reporting that the court is likely to reject the appeal this evening.

Spain’s Parliament passed the country’s equal marriage bill in June 2005 when it was Socialist-controlled.

The Popular Party, who opposed the measure, has since come to power.

The law angered the Spanish Catholic Church but opinion surveys showed most Spaniards backed it.

Prime Minister Mariano Rajoy has previously said he supports civil unions for same-sex couples, but does not think they should be called marriages.

Spain was the world’s third country to give full legal recognition to same-sex marriages after the Netherlands and Belgium and seventeen days ahead of Canada.

On Wednesday, French President Francois Holland’s government will officially unveil his country’s proposed draft equal marriage bill, after it is presented to the cabinet.
