A federal judge announced today that he would suspend a taxpayer-funded sex change operation for a man convicted of killing his wife.

US District Judge Mark Wolf, who ordered earlier this year that Michelle Kosilek must be allowed the surgery, said he would suspend his order until an ­appeal of his ruling by the ­Patrick administration.

Wolf, who has called his ruling on the surgery “unpopular and misunderstood,” also rejected a request for electrolysis treatment for Kosilek, saying that would have to come as part of a new case.
