State election officials are expected to decide by the end of the month whether a campaign against the law has collected enough signatures to qualify for the November ballot. If enough signatures were collected, the year-old law would be suspended until the public vote was held.

The law has sparked opposition from labor unions because emergency managers are allowed to modify union contracts.
