Three states including Idaho, Tennessee, and Texas are slated to have abortion trigger bans take effect by the end of August in the wake of the Supreme Court‘s June decision to overturn Roe v. Wade.

Although the Supreme Court’s ruling on Dobbs v. Jackson Women’s Health Organization came back in late June, the high court’s judgment did not go into effect until July 26. The three states are part of a group of 13 with laws designed to be “triggered” and take effect immediately without the need for further action once Roe was overturned — but some laws require 30 days for enforcement measures to go into effect or need certification from the state’s attorney general. This Wednesday marks 30 days.
