Every day in Family Court the story was the same: 75 percent of the people before Judge Nicolette M. Pach '70 were addicted to drugs or alcohol. She'd order treatment, they'd come out of a program and go right back and do it again. Their children were born addicted or were neglected, Pach says. The kids were suffering.     In December 1997, Pach launched the Family Drug Treatment Court two afternoons a week in her courtroom in New York's Suffolk County. By last fall, 25 people, most of them women addicted to drugs or alcohol after experiencing sexual abuse or domestic violence, were in the program. Pach, who called on her knowledge of criminal drug courts "and went from there," aims to protect the children from harm, keep their families together and rehabilitate addicted parents.     Child protection and other social service agencies form a steering committee and petition the judge to help when somebody misuses drugs or alcohol. Pach sees the offender once a week: Did you take the baby to the doctor for immunization? Are children's issues being met? A case manager oversees what's going on, including drug testing in the courthouse when the parent comes in. An expanded team working with the family includes the child's attorney, court attorney and child protection officer. "It's very closely monitored," said Pach.     By coming to court, staying drug free, attending group therapy, getting jobs, people in the program take on more and more responsibility--and begin to feel good about themselves, says Pach, who claims that she "always had a bit of a social work bent." She went directly from her Colby government major to Boston College Law School but looked into doing a social work degree at the same time. Her first job was legal aide on the defense side. "I've always been interested in juvenile issues. They moved me," she said.     She's presented her thinking at a Health and Human Services workshop in Cincinnati, and other courts emulating hers have started up around the country, but a lot of work remains, Pach says, such as getting drug and child services working together. A 12- to 18-month drug program isn't acceptable if a newborn's mother will be absent all that time, seriously impairing the child's proper development. "My focus is on providing a stable home within a year," she said.      Her success so far has been "pretty good, but it's easier to have the idea than to do the idea," she said. "What keeps me sane is my husband, Stephen Kunken, and my boys, nine and fifteen. It's a busy and healthy family. When I leave here, I go home to sanity."     It's also rewarding when everybody comes to court "clean." One woman had custody restored; another, beaming from ear to ear, carried in her baby. Pach directs each person to bring a picture of the child. "This," the judge reminds them, holding up the photo, "is why we're doing this."     When one young mother who went off on a bender finally appeared back in court on an outstanding warrant, Pach said to her, "I have been so worried about you!" Pach says the woman, who was astonished that anybody cared, voluntarily went straight into a 28-day program.
