Opponents of the effort to call a referendum on Michigan's emergency manager law plan to file a challenge today to the petitions turned in last month.
The group Michigan Forward turned in almost 237,000 petition signatures to state elections officials last month. The group wants to get a question on the November ballot asking voters to overturn the state's local emergency manager law.
Michigan Forward opted not to get its petition pre-approved by state elections officials.
And now opponents of the referendum drive say they've found what they're calling a "fatal error" on the petitions.
