LANSING (AP) — A broad ballot proposal that would change the makeup of state courts and the Legislature appears to have enough voter signatures to make the November ballot, state election officials said Tuesday.

That likely means the ballot eligibility of the Reform Michigan Government Now proposal will be decided in court. A coalition called Citizens Protecting Michigan’s Constitution has sued to try to keep the proposal off the ballot.

The group, which includes the Michigan Chamber of Commerce, on Tuesday told the Michigan Court of Appeals the measure is too broad to be covered in a single ballot proposal. Opponents say the sweeping changes should be proposed either in a convention to rewrite the constitution or in a series of separate measures.

‘‘What voters are being asked to do is take all 36-plus changes and vote them up or down in one proposal,’’ said Peter Ellsworth, an attorney for the proposal’s opponents.
