Fears that a conservative U.S. Supreme Court would inspire a wave of anti-abortion legislation across the country appear to have been warranted, a study of state-level bills introduced this year suggests.

According to a report the Planned Parenthood Federation of America released Friday, legislation limiting abortion in 2021 has skyrocketed in comparison to a similar time frame in 2019. Compared to bills introduced from January through mid-March 2019, medication abortion restrictions and bans have tripled to 33, anti-abortion constitutional amendments have more than tripled to 14, and states have enacted 12 abortion restrictions this year, compared to just one by this point in 2019.

Overall, state legislatures have introduced 516 abortion restrictions, compared to 304 by mid-March 2019. Those pieces of legislation are clearly about power and control over our bodies, PPFA president and CEO Alexis McGill Johnson said, noting the bills disproportionately impact people of color, people with low incomes and LGBTQ+ people.

These policies are designed to make it harder for people to exist, she said.

Many of the bills have already faced swift legal challenges, preventing them from going into effect on schedule or at all. But proponents of the most restrictive legislation say thats all part of the plan to push legally dubious abortion legislation up to the Supreme Court, now firmly conservative with Donald Trump s three additions, with the goal of forcing the justices to revisit Roe v. Wade.
