A state Superior Court judge has granted class certification for a lawsuit on behalf of more than 9,000 Metropolitan District Commission customers who claimed the nonprofit municipal corporation charged them an unlawful annual water surcharge.

The ruling allows the litigation to proceed on behalf of a class of consumers from East Granby, Farmington, Glastonbury and South Windsor, who were charged a $158 annual surcharge in 2012, then $423 the following year and $199 in 2014.

MDC argued it was within its rights to charge an annual fee, but the Connecticut Supreme Court ruled against it, finding the surcharge illegal.

And now Hartford Superior Court Judge Thomas Moukawsher concluded that one umbrella suit is a better option than multiple proceedings.

“The class action for thousands nicked for relatively small change makes sense,” Moukawsher ruled. “It is the only way wrongs of these types will ever be addressed.”

Representing MDC are Robinson & Cole attorneys Wystan Ackerman and Kevin Daly. Ackerman relayed the following emailed statement from Christopher Stone, assistant district counsel for the Metropolitan District Commission: “The Metropolitan District respectfully disagrees with the court’s ruling and intends to continue to vigorously defend this case. The non-member town surcharge dates back to 1942. The District does not believe it has any implied contract with its customers requiring it to refund charges after this charge had been accepted and paid by its customers unchallenged for many years. The court’s certification of a class on an implied contract claim appears to be unprecedented nationwide.”

Three Izard, Kindall & Raabe attorneys—lead counsel Craig Raabe, Christopher Barrett and Oren Faircloth—filed the class action on behalf of fellow attorney and MDC consumer William Paetzold and his wife Lori.

“The plaintiffs are very pleased with the court’s common-sense ruling,” Raabe said.

Here is a look at the attorneys in the case.
