Three Puerto Rico lawmakers said Monday that they plan to sue Governor Alejandro Garcia Padilla, a Democrat, over his decision to no longer defend in court the territory's ban on gay marriage.

The decision paves the way for Puerto Rico, a U.S. territory, to legalize gay nuptials.

Senator Angel “Chayanne” Martinez and Representatives Maria Milagros Charbonier and Carlos Johny Mendez Nuñez, all members of the Partido Nuevo Progresista (PNP), said they will seek to declare unconstitutional Padilla's decision without first going through a democratic process.

“We believe it is totally contrary to the law, contrary to the constitution of Puerto Rico and contrary to the democratic foundations of our system of government for our governor to have taken a position on same-sex marriage,” Charbonier told reporters during a press conference.

In previous comments, Charbonier called the decision “a slap in the face.”

The reversal has also angered religious leaders, with the Catholic Church calling for a referendum on the issue.
