*Adoption services: Catholic Charities of Boston refused to place children with same-sex couples as required by Massachusetts law. The group withdrew from the adoption business in 2006.
*Housing: In New York City, Yeshiva University’s Albert Einstein College of Medicine, a school under Orthodox Jewish auspices, banned same-sex couples from its married dormitory. In 2001, the state’s highest court ruled Yeshiva violated New York City’s ban on sexual orientation discrimination and the school now lets same-sex couples live in the dorm.
*Medical services: On religious grounds, a Christian gynecologist in California refused to give his patient in vitro fertilization treatment because she is in a lesbian relationship. (He referred the patient to a partner in his practice group, who agreed to provide the treatment.) The woman sued and the case is pending before the California Supreme Court, which is expected to rule in favor of the lesbian.
*Civil servants: A clerk in Vermont refused to perform a civil union ceremony. In 2001, in a decision that side-stepped the religious liberties issue, the Vermont Supreme Court ruled that he did not need to perform the ceremony because there were other civil servants who would. However, the court did indicate that religious beliefs do not allow employees to discriminate against same-sex couples.
Wedding services: A same sex couple in Albuquerque asked a photographer to shoot their commitment ceremony. The photographer declined, saying her Christian beliefs prevented her from sanctioning same-sex unions. The couple sued, and the New Mexico Human Rights Commission found the photographer guilty of discrimination and ordered her to pay the couple’s legal fees. The photographer is appealing.
Wedding facilities: Ocean Grove Camp Meeting Association of New Jersey, a Methodist organization, refused to rent its boardwalk pavilion to a lesbian couple for their civil union ceremony. The couple filed a complaint with the state civil rights commission. The commission ruled that the property was open for public use and therefore the Methodist group could not discriminate against gay couples using it. The case is ongoing.
