The Massachusetts Office of Campaign and Political Finance (OCPF) missed a self-imposed deadline this week to release updated regulations limiting political contributions from labor unions.

A spokesperson for the agency said it could take several more weeks to work out the details and release the new rules.

The push to update a labor union contribution loophole comes after a 2018 court ruling upholding the state’s ban on corporate contributions.

The ruling acknowledged the significant difference for labor unions.

The draft regulations released in March seek to reduce the amount of money a union can contribute to a candidate annually from $15,000 to $1,000.
