Opponents of Maryland s recently passed gun-control measure say they will seek to overturn it in court, not on the ballot.
Delegate Neil Parrott, a Washington County Republican, made the announcement Wednesday evening in Jessup.
Representatives from gun-rights groups said they support going to court instead of trying to petition it to the ballot.
They say they are confident the measure is unconstitutional.
The measure, proposed by Democratic Gov. Martin O'Malley, makes the state's already-strong gun laws among the toughest in the nation.
Under the bill, Maryland would become the first state in nearly 20 years to require people who buy a handgun to submit fingerprints to state police. The measure also bans 45 types of assault weapons, although people who own them now will be able to keep them.
