New laws banning abortion are are scheduled to take effect Thursday in four states – Idaho, Oklahoma, Tennessee and Texas – two months after the U.S. Supreme Court overturned the 1973 landmark Roe v. Wade ruling that established a constitutional right to abortion. 

A ban in another state, North Dakota, was scheduled to take effect Friday, but a state judge Thursday delayed that until a legal challenge to the ban could be considered.

What is happening and why? All but the Oklahoma legislation are the result of so-called “trigger” laws, bills approved in the past to ban abortion that would take effect – i.e., be triggered – only if the Supreme Court overturned Roe and gave states the power to severely limit or even outlaw the procedure. 

How many states have bans? Are more bans coming? Thirteen states have trigger bans that have taken effect, are scheduled to or are being reviewed by the courts. They already have taken effect in Arkansas, Kentucky, Louisiana, Mississippi, Missouri and South Dakota. Without Roe, some project as many as 26 states will restrict or ban abortion at some point short of viability.

What states are banning abortion and when?

The laws going into effect this week basically amount to a near-total ban on abortion. 

The Texas law, passed in 2019, bans the procedure after fertilization except in cases of life-threatening or severe health conditions.

Tennessee’s trigger ban was also approved in 2019. It similarly would ban all abortions, except in the case of severe or life-threatening health conditions for the patient.

Idaho’s legislation, passed in 2020, bans abortion and makes anyone who performs an abortion subject to a felony punishable by two-to-five years in prison. Much of the law will take effect Thursday, but a U.S. district court judge Wednesday stopped the state from prosecuting anyone performing an abortion in a medical emergency until a legal challenge is decided.

In North Dakota, a judge Thursday temporarily stopped an abortion ban from taking effect Friday, according to the Associated Press. Burleigh County District Judge Bruce Romanick said he wanted more time to make a proper judgment in a egal challenge to the ban, enacted in 2007, by Red River Women’s Clinic. That clinic had been North Dakota’s sole abortion provider until it moved across the state border to Minnesota earlier this month.
