The lawyer for a methadone clinic that wants to move into Warren is threatening to sue the community over a decision to put a halt to the move. The selectboard approved a six-month moratorium against methadone clinics last month. It came shortly after a developer signed a deal to buy the former elementary school. Then word got out he planned to open a methadone clinic there, sparking a public outcry.The lawyer for C-R-C Health Group, which wants to run the clinic, says the moratorium violates the Americans With Disabilities Act.James Green says the decision discriminates against recovering opiate addicts.The lawyer for Warren says C-R-C has no legal standing to sue. The town manager says selectmen are moving forward with the issue and a new committee to address methadone clinics and medical marijuana facilities in Warren meets for the first time next week.
