NEWTOWN – Voters will go to the polls in November with the unusual opportunity to eliminate an elected body of town government that leaders say has existed in error for 20 years.

“I don’t want to get into the whole history of it, but it was a mistake that we have a Board of Finance,” town attorney David Grogins said during a discussion last week of charter revision questions that will go to voters on Nov . 8. “It was clearly a mistake.”

Grogins was referring to the biggest change to Newtown’s charter that voters will decide at the polls — whether to disband the Board of Finance in the name of streamlining the annual budget process and ridding residents of a duplicative layer of government.

“We worked with it as an error for many years and the intent here I hope is to rectify the error,” Grogins said at an Aug. 17 meetings of the Legislative Council, a 12-member elected body that by law is the fiscal authority in Newtown. “Few towns have legislative authorities and boards of finance like that.”

If leaders have their way, Newtown will not be one of those towns after the November election.

The only question is whether the voters will understand from the limited description on the ballot what it will mean for Newtown to eliminate its six-member Board of Finance, one of the four major elected governing bodies in town, along with the Board of Selectmen, the Board of Education and the Legislative Council.
