The Bethel Board of Selectmen has voted to hire a law firm to investigate Eversource’s response to last month’s tropical storm.  The firm Cohen and Wolf will counsel the town, which filed last week for intervener status in the Public Utilities Regulatory Authority’s investigation into Eversource.  First Selectman Matt Knickerbocker says not only will the municipalities be able to cross-examine witnesses, they could seek compensation for losses.  Newtown, Ridgefield and New Fairfield have all hired the same law firm.  Each town is expected to pay about 25-thousand dollars.  New Milford is also looking to investigate storm response.
