ABORTION rights groups are flooding state courts with lawsuits seeking to stop the enforcement of bans that began taking effect after the U.S. Supreme Court overturned the 1973 Roe v. Wade case that legalized abortion nationwide.

Meanwhile, Democratic-led states are trying to pass legislation that would strengthen protections for abortion providers and patients, anticipating an influx of women seeking to terminate pregnancies from abortion-hostile states.

Here are the latest legal and legislative developments in the shifting U.S. abortion landscape:

* In Ohio, Planned Parenthood and the Center for Reproductive Rights on Wednesday sued to block the state from enforcing a ban on abortions past six weeks of pregnancy. The ban went into effect on Friday when a federal judge lifted an order that had blocked the law for three years on the grounds that it was unconstitutional.

The case will be heard by the Ohio Supreme Court, where four of the seven justices are Republican. The Ohio Supreme Court in a brief order directed the state to respond on Thursday.

Judges in Texas, Utah and Louisiana have granted temporary injunctions on abortion bans in those states since the U.S. Supreme Court's abortion ruling on Friday. 

* The Massachusetts House of Representatives on Wednesday voted 136 to 17 to protect healthcare workers who provide abortions and gender-affirming care in a bill that would also bar state agencies from complying with federal or other states' attempts to prosecute Massachusetts abortion providers. The bill now goes to the Senate, where the Democrats hold an advantage of 37 to 3.

* In Kentucky, Jefferson Circuit Judge Mitch Perry heard abortion rights advocates make their case that the state constitution protects the right to end a pregnancy. He will decide whether to block enforcement of the state's six-week ban and trigger law, which shut down abortion services last Friday after the high court's ruling.

* In Florida, the Second Judicial Circuit Court scheduled a hearing for Thursday in Planned Parenthood's case to block the state from enforcing a ban on abortions past 15 weeks. The law is due to take effect on Friday.

* In West Virginia, the state's only abortion clinic and its staff filed a lawsuit in state court to block the enforcement of a pre-Roe abortion ban, which has forced the clinic to cease abortion services since Roe was overturned.

* The Supreme Court as soon as Thursday morning could act on three cases that were on hold pending its decision to overturn Roe v. Wade.

In one, Arizona wants to implement a law that bans abortions when the decision is based on genetic abnormalities. Arkansas has a similar appeal pending seeking to revive a law that bans abortions performed due to fetal evidence of Down syndrome. In the third case, Indiana is a seeking to expand the scope of a law that requires parents of minors seeking abortions to be notified.
