This ban is stricter than the 15-week ban that was passed in 2022. However, pro-choice groups will likely seek to get an initiative that would overturn the ban on the ballot in November.

This market resolves based on whether there is such an initiative on the ballot, and on whether it passes. To count for this market, the initiative only needs to be enough to repeal/nullify the 1864 law, not the newer 2022 law.
