Doctors refusing treatments on medical grouns

Although we are usually concerned with issues arising out of a patient's refusal of medical treatment (abortion, transfusions, euthanasia, etc.), some Doctors have been getting into hot water after refusing treatment due to their religious convictions.

USA Today reports:

When does the freedom to practice religion become discrimination?
The California Supreme Court is being asked to answer that question when it hears a legal dispute between a lesbian mom and two doctors who refused to artificially
inseminate her for religious reasons.
...
The dispute arose in 2000 after San Diego-area doctors Christine Brody and Douglas Fenton refused to artificially inseminate Benitez, a lesbian who lives with her partner, Joanne Clark, in Oceanside, north of San Diego.
...
In 2001, Benitez sued the doctors, claiming that they violated California's anti-discrimination laws that protect gays and lesbians.

Apparently, over 40 differents groups have filed with the court to be heard over the matter, both on the side of Doctor's religious rights and the opposing side.
