BOSTON — Massachusetts car manufacturers and independent repair shop owners are gearing up for what could be another major battle at the ballot box.

The Massachusetts Right to Repair Coalition on Tuesday filed a petition with Attorney General Maura Healey’s office for a ballot initiative to update the state’s 2012 Right to Repair law.

“It has to be updated to cover new technologies and new vehicles so consumers can get the car repair of their choice,” said Tommy Hickey, director of the coalition, which includes independent repair shops, parts stores and consumer groups.

But a newly formed coalition that includes auto manufacturers says the original law already covers any information needed to fix a car. “This goes far beyond what is needed to diagnose and repair a vehicle,” said Conor Yunits, a spokesman for that coalition.

The right to repair battle is already shaping up as a contentious and potentially expensive ballot fight, a repeat of the ballot question that led to the state’s 2012 law. It is one of 13 ballot questions that have been proposed for the 2020 ballot.

Wednesday was the deadline for organizations to submit proposed 2020 ballot questions to Healey’s office. According to Healey, 14 groups proposed 16 initiative petitions. Of these, 13 are for 2020 ballot questions and three are for constitutional amendments, which could not go on the ballot until 2022.

Healey has until Sept. 4 to certify whether the proposed questions are constitutional. Question proponents will then have until Dec. 4 to gather at least 80,239 signatures. The Legislature will have a chance to act on the proposals. If lawmakers do not act by May 2020, proponents must gather another round of signatures to get on the ballot.

The right to repair battle is a technical one, involving whether the current law should be updated to include telematics — wireless information that vehicles collect and send to the manufacturer. This information goes beyond what is generally used for repairing a car today, and includes real-time information that can identify, for example, when a car’s brakes are wearing out.

Several petitions relate to election laws.

One would establish ranked-choice voting, in which voters rank candidates in order of preference.

Voter Choice Massachusetts Executive Director Adam Friedman told The Republican/MassLive.com last year that ranked-choice voting changes politics from “a zero-sum game where various factions battle it out” to one that can be more unifying and inclusive, since politicians have to get support from a broader base of voters. Friedman said it eliminates the idea of “spoiler” candidates, in which a third-party candidate is blamed for allowing a less favored candidate to win.

Emily Fitzmaurice, a spokeswoman for the group, said Wednesday, “Bringing Ranked Choice Voting to Massachusetts is a commonsense way to re-energize and empower voters across the Commonwealth at this critical time in our democracy.”

Another petition would change the way primary elections are conducted so that the top two vote-getters advance to the general election, regardless of party.

Petitions seek to limit the campaign finance rights of corporations and limit political donations by out-of-state residents.

A proposed constitutional amendment would restore the right to vote to convicted felons.

Several petitions deal with hot button issues, including gun control, immigration and abortion.

One initiative petition would require all gun owners to store their guns in a certified gun safe. It would hold gun owners liable for any crimes committed with their guns if the guns are unsecured.

A petition would prevent Massachusetts from becoming a “sanctuary state,” by explicitly authorizing local law enforcement to cooperate with federal immigration authorities.

A proposed constitutional amendment would ban public funding of abortion. A similar amendment was introduced and failed to make the ballot in previous years. Today, MassHealth, the state Medicaid program, does cover abortion services.

“The annihilation of babies in the womb should not be paid for by Massachusetts taxpayers,” said ballot committee Chairman Thomas Harvey in a statement. “Instead of trying to make abortion quick, cavalier, and free, we as a society owe it to women to help them choose life instead.”

With state nursing homes facing increasing financial struggles, one petition would change the way the state sets its reimbursement rates for nursing homes.

Two petitions aim to protect people with disabilities by barring, among other things, administering an electric shock to a person with a disability in order to change their behavior.

Other initiative petitions deal with safe whale fishing, reducing the risks of technology, expanding the ability of food stores to obtain licenses to sell beer and wine, and limiting sick leave payouts for state employees who leave their jobs.
