HALIFAX - Premier Darrell Dexter of Nova Scotia is dismissing a threat of a legal challenge over his government's proposal to redraw the province's electoral map.

Dexter responded Tuesday just as the Acadian Federation of Nova Scotia said it intends to challenge legislation that would merge the protected Acadian ridings of Clare, Argyle and Richmond with other ridings.

"I don't know how it could be illegitimate," Dexter said.

"We brought forward a fair process, one that seeks to balance the question of minority rights with the right of all people to feel that their votes count equally and that balance is something that the commission had to deal with. It did."

The federation issued a statement saying it feels betrayed by the NDP government, accusing it of interfering in the work of the independent commission that was tasked with updating the boundaries.

In September, the Electoral Boundaries Commission recommended four minority ridings — including a riding that has a large black population — should be merged with neighbouring ridings to ensure relatively equal representation.

Premier Darrell Dexter says the commission's terms of reference provided for a balance between minority rights and equal representation.

Dexter says the legislation should withstand a legal challenge.
