Brian Edwards and Tom Privitere, along with a photographer, have filed a lawsuit against Public Advocate of the United States. The lawsuit came to be after a photo of the openly gay couple was used by Public Advocate in one of the organization’s fliers to spread anti-gay messages.

Privitere and Edwards were photographed in front of the Brooklyn Bridge in 2010. The couple’s engagement photo was then used by Public Advocate in two of its fliers. The pair claim that the organization did not seek their permission to use the image, therefore violating copyright laws.

They are seeking an award for damages and related court costs.

Christine Sun, attorney for the couple, has called the use of the image “wholly gratuitous.” Public Advocate’s president, Eugene Delgaudio, told NBC News that he was looking into the matter of how the photograph was obtained, but refused to comment further.
