Justices in Ohio are weighing arguments that will determine the fate of Ohio's newly drawn legislative map.
Lawyers sparring before the Ohio Supreme Court Tuesday disagreed over the constitutionality of the new lines and the process by which they were drawn.
The attorney for Democrats, who filed suit on behalf of a group of Ohio voters, said it's clear the maps favoring Republicans violated provisions against gerrymandering.
The litigation says the maps of 99 House and 33 Senate districts split cities, counties and other community units more than 250 times, seeking political advantage for GOP candidates.
An attorney for Republicans said the map is legal and Democrats aren't able to prove their allegations.
The court has said its decision will be timed not to impact the 2012 presidential race.
