BOSTON — A ruling ordering Massachusetts prison officials to provide sex-reassignment surgery to an inmate is being praised by advocates as important recognition that the surgery is a legitimate treatment for gender-identity disorder, even as critics including Sen. Scott Brown call it "an outrageous abuse of taxpayer dollars."

U.S. District Judge Mark Wolf ruled Tuesday in the case of Michelle Kosilek, a transgender inmate serving life in prison for murder. Wolf said the Department of Correction must provide the taxpayer-funded surgery because it is the only way to treat Kosilek's "serious medical need."

Kosilek was born male but has received hormone treatments and now lives as a woman in an all-male prison. Kosilek was named Robert when married to Cheryl Kosilek and convicted of murdering her in 1990.
