(Bloomberg) -- Pro-choice supporters don’t plan to let the weeks leading up to the Supreme Court’s official ruling in Dobbs v. Jackson Women’s Health Organization, expected this June, to pass by quietly: A coalition of more than 30 advocacy groups are organizing a nationwide day of protests on May 14.

Groups including Planned Parenthood, MoveOn, UltraViolet and Women’s March, have announced that “Bans Off Our Bodies” rallies will take place that day across the U.S., including so-called “anchor” events in Chicago, Los Angeles, New York and Washington, D.C. Protests are planned in at least 200 additional cities, from Anchorage to Wilmington, and a virtual event is slated to occur in tandem.

The opinion draft written by Justice Samuel Alito that was leaked last Monday would reverse the nearly 50-year precedent set by Roe v. Wade. But the text was only a draft, and justices may change their opinions and write new drafts up until the time of the case’s ruling. The call for protests is in part intended to create a groundswell of pressure that may influence that final decision.

“No one expects a protest or a rally to change things the next day. These are all about building longer-term power together,” said Sonja Spoo, the director of reproductive rights campaigns at UltraViolet, “although we certainly hope that the Supreme Court takes heed of the anger that they're seeing in the streets.” 

Organizers urged people to gather in front of their local city halls last Tuesday, and campus walkouts at colleges across the country added to the momentum on Thursday. This past weekend protestors also marched between Justice Brett Kavanaugh and Chief Justice John Roberts’ homes in Chevy Chase, Maryland, prompting criticism and a statement from White House Press Secretary Jen Psaki that judges “must be able to do their jobs without concern for their personal safety.”

The rallies build on decades of activism on behalf of abortion access and events including the nationwide Women’s March in January 2017, where millions of people rallied in cities nationwide, and years of Black Lives Matter protests that hit a critical mass in June 2020. Other groups are assembling events leading up to the court’s decision as well, such as The National Council of Jewish Women’s plan for a May 17 event.

“Abortions are already terribly inaccessible for too many people, and increased restrictions wrought by the leaked draft Dobbs opinion will disproportionately hurt people in poverty, people who can’t afford to travel to states where abortions may still be available,” said Anika Seth, an organizer with the student-led Reproductive Freedom Movement and a freshman at Yale University who intends to join the May 14 demonstrations. “They will disproportionately hurt trans and nonbinary people, who experience sexual violence at greater rates and are already ostracized by our healthcare system. Incarcerated people. People in detention centers. We have to do better for all of them, for all of us.”
