Advocates say the complaint filed with the state Division of Human Rights is among the first of its kind since New York legalized same-sex weddings last year.
Melisa Erwin and Jennie McCarthy, of Albany, say they filed the complaint Oct. 11 after Liberty Ridge Farm told them they could not use the site for their wedding next summer.
A spokesman for the owners of Liberty Ridge Farm says the couple acted in line with their values. Jason McGuire, of New Yorkers for Constitutional Freedoms, says the owners feel that their rights are being violated and that they will contest the complaint.
