“I have determined that final certification ... is warranted at this time,” State Elections Administrator Linda H. Lamone said in a letter to Derek McCoy, executive director of the Maryland Marriage Alliance.

As a result, voters statewide will determine whether to uphold the gay nuptials law signed by Gov. Martin O’Malley (D) in March.

A total of 55,736 signatures were required to force the public vote. As of June 21, elections officials had verified 109,313 signatures that were submitted by McCoy’s group at the end of May.

Lamone’s letter informed McCoy that officials did not even bother to examine a second batch of 39,743 signatures submitted toward the end of last month.

Both sides have been gearing up for months for the expected ballot measure.
