A Massachusetts citizens commission that will advocate for the regulation of corporate political donations, which was approved at the ballot in November, will be open for applications this January.

“The next step is making sure we get great civic-minded citizens around the commonwealth applying,” said Jeff Clements, president of American Promise, a Concord-based advocacy group that pushed for the ballot question.

Question 2, which passed with 71.4 percent of the vote, established a “citizens commission” to research and advocate for a constitutional amendment overturning the U.S. Supreme Court’s 2010 ruling in Citizens United.

The court decision allowed corporations to spend unlimited amounts of money supporting or opposing a candidate as long as they did not coordinate directly with the candidate.

Under the new state law, a 15-member commission will be appointed, with the governor, attorney general, secretary of state, Senate president and House speaker all getting three picks. The application process will be public, with every application available to the public on a website established by the governor’s office.

An aide to Gov. Charlie Baker confirmed that the governor’s office is in the process of developing the website, which will open in January to accept applications. The law establishes that the committee members should represent a range of geographic, political, and demographic backgrounds.

“It’s not one of these Beacon Hill-only appointments,” Clements said. “It’s really an open, transparent process everyone is welcome to participate in.”

The commission is charged with researching and reporting on the impact of political spending in Massachusetts; the limitations the U.S. Supreme Court imposed on the state in regulating political contributions; recommendations for constitutional amendments; analysis of constitutional amendments introduced in Congress; and recommendations for advancing proposed constitutional amendments.

The appointments are supposed to happen in the first quarter of 2019, with a meeting scheduled before May 1 and a report due by Dec. 31.

Although 19 states have passed resolutions calling for a constitutional amendment to overturn Citizens United, Massachusetts is the first to create a citizens commission. Clements said his organization will be watching Massachusetts and potentially advocating for other states to create similar commissions through ballot votes in 2020.

“Seventy-two percent of voters across the commonwealth approved of this constitutional amendment to get big money out of politics,” Clements said. “Now the job is to make it happen.”
