MYRTLE BEACH, S.C. - Voters in two subdivisions in Horry County thought they had agreed to join Myrtle Beach last week. But the annexation vote has been ruled invalid.

Voters agreed by more than 2-to-1 to have 600 acres including two subdivisions and more than a dozen businesses annexed into the city.

But Myrtle Beach City Attorney Tom Ellenburg says the vote was invalid.

That's because voters in the subdivisions went to their usual polling places to cast their ballots. But the polling places were not within the areas to be annexed where they must be under state law.

Officials say the process will have to start again with new polling places.
